The non-negotiables: what you genuinely cannot skip
If you take nothing else from this guide, take this short list, because these are the items that make or break a Portugal trip. First, grippy and broken-in walking shoes, because you will spend whole days on steep calcada cobbles that turn lethally slick in the lightest rain. Second, a light rain shell, because Atlantic weather flips fast and an afternoon shower is common in every season. Third, a warm layer, even in July, because the sea breeze drops the temperature hard after dark. These three solve the most common discomforts I see in visitors, and not one of them is glamorous.
The other two non-negotiables are about protection rather than weather. Sun cover comes next: a high-factor sunscreen, a hat and sunglasses, because the light here is stronger than its mild temperatures suggest and people burn on overcast days near the coast. Last, a zipped crossbody bag, the quiet workhorse of a Portugal trip, which keeps your phone and wallet secure on the trams, in the markets and at the busy stations where opportunist pickpockets work. Get these five right, shoes, shell, layer, sun and bag, and almost everything else in your luggage is negotiable. My three days in Lisbon itinerary assumes you have all five.
Shoes first: surviving the calcada
I am going to spend a whole section on footwear because it matters more than anything else you pack, and it is the thing most visitors get wrong. Calcada portuguesa, the beautiful mosaic pavement of polished limestone that covers the historic centres, is worn smooth by centuries of feet and is genuinely treacherous when wet. Smooth-soled shoes, leather city boots, fashion trainers and most sandals will slide on it, especially downhill, especially in light rain. Every season I see at least one visitor take a real fall.
The fix is simple and unglamorous: shoes with a proper rubber grip, broken in before you travel so they do not blister you on the long days.
Beyond grip, prioritise comfort over style, because Portugal is walked rather than driven. A first-time visitor to Lisbon or Porto can easily cover ten kilometres a day across hills, and the cobbles tire feet that pavements never would. One good pair of cushioned walking shoes does ninety percent of a trip. Add a second lighter pair if you have room, sandals with grip for the Algarve or a smarter shoe for an evening out, but do not let either replace the workhorse pair. If you can only bring one thing on this entire list, bring the right shoes, and break them in at home first.
Packing by season: spring, summer, autumn, winter
Summer, June to September, is hot and dry inland and milder on the coast. Pack light breathable clothes, swimwear, strong sun protection, and yet still a warm layer and a light shell for the evenings and for the cooler Atlantic towns. Do not be the person shivering on a Tagus ferry in August because the forecast said 30 degrees. Spring and autumn, roughly March to May and October to November, are my favourite seasons to pack for, mild days and cool evenings, where layers do all the work. A t-shirt, a long sleeve, a warm mid-layer and a rain shell cover almost any day you will meet.
Winter, December to February, is the season people most underestimate. Portugal is mild rather than warm, with damp grey spells, real rain, and indoor heating that is often weak by northern European standards, so houses and small guesthouses can feel cold. Pack a proper warm layer, a waterproof, and clothes you can wear in bulk indoors. The exception at the other extreme is the Serra da Estrela mountains, where it genuinely snows and you need cold-weather gear. Whatever the season, the through-line is the same: Portugal asks for layers, not for a single thermostat setting, because the gap between midday and midnight is always wider than you expect.
What not to overpack
Just as important as what to bring is what to leave at home, because the classic Portugal mistake is packing for an imagined heatwave and arriving with a suitcase full of clothes you never wear. You do not need a different outfit for every day. Portugal is relaxed and casual, even in city restaurants, so a few mix-and-match basics in colours that work together beat a wardrobe of single-wear pieces. Most accommodation has laundry or there is a launderette nearby, so plan to wash mid-trip rather than packing two weeks of clothing for a two-week trip. This single shift is what gets most people down to carry-on.
Leave the heavy hairdryer, the full-size toiletries and the just-in-case gadgets. Guesthouses and hotels supply hairdryers, you can buy toiletries on arrival, and the gadget you packed for a hypothetical never gets used. Formal wear is rarely needed unless you have a specific event, since even smart Lisbon dinners lean smart-casual. And resist the urge to pack heavy beach gear; towels are usually provided or cheap to buy, and the Algarve sells everything a beach day needs. The goal is a bag light enough to carry up a flight of Alfama stairs without resentment, because at some point you will have to.
Electrics, SIM and staying connected
Portugal uses the Type F plug, the round two-pin Schuko socket, at 230 volts and 50 hertz, shared with most of continental Europe. Visitors from the UK need a simple adapter; visitors from the US and elsewhere need an adapter too, and should check that each device handles 230 volts, which phones, laptops and most modern chargers do but some hairdryers and small appliances do not. One multi-port USB plug adapter charges a whole family's devices from a single socket and saves you packing several. It is one of the highest-value small items in any Portugal bag.
For data, you have three good options. European visitors can roam at home rates under EU rules, which is the simplest path. Everyone else should consider an eSIM, bought and activated on your phone before you even land, or a physical Portuguese SIM from a network such as MEO, NOS or Vodafone, sold cheaply at the airport and in shops. Data is inexpensive here, and having it untethers you from hunting for wifi, lets you use maps on the back roads, and makes calling a Bolt or Uber effortless.
Sort connectivity before your first day rather than during it, especially if you are heading straight out to explore Porto or the coast.
Money, cards and transport passes
Portugal is firmly a card country now. Contactless payment works almost everywhere, from city restaurants to many market stalls, and you can tap your way through most of a trip without ever visiting a cash machine. Bring a contactless debit or credit card, ideally one with low foreign-transaction fees, and a backup card kept separately in case one is lost or blocked. That said, do carry some cash. Small village bakeries, a few old tascas, tips, church donations and the occasional rural cafe still prefer or only take coins and notes, and being caught cashless at a counter is an avoidable embarrassment.
For transport, do not buy single tickets one at a time. In Lisbon, pick up a rechargeable Viva Viagem card for a few cents at any Metro machine and load it with passes or pay-as-you-go zapping credit; it covers the Metro, trams, buses, funiculars and the suburban trains. Porto uses the equivalent Andante card on its Metro and buses. For longer hops between cities, the CP national rail network is comfortable and worth booking ahead online for the faster intercity trains. Sorting a transport card on arrival, before your first ride, saves money and the small daily friction of queuing for tickets.
The anti-pickpocket bag and staying safe
Portugal is a genuinely safe country with low rates of violent crime, and I want to be clear about that before talking about bags, because the risk here is petty theft, not danger. Opportunist pickpocketing happens in the predictable places: crowded trams, especially Lisbon's famous number 28, busy stations, packed miradouros and tourist markets. The defence is dull and effective. A crossbody bag worn across the front of your body, with a real zip, keeps your phone and wallet where you can feel them. A back pocket on a tram is an invitation, and a backpack worn on your back in a crowd is the easiest target there is.
Beyond the bag, the habits matter more than any gadget. Keep your phone in hand or zipped away rather than loose in a pocket, split your cash and cards between two places, and stay aware near the doors of a crowded tram, which is exactly where the lifting happens as people push on and off. Leave passports and spare cards in your accommodation safe and carry a photo of the passport on your phone. None of this should make you anxious. Portugal feels relaxed because it largely is, and these small precautions simply keep a wonderful trip free of the one common annoyance that can sour it.
Carry-on only: doing a week with one bag
Most Portugal trips can and should be done carry-on only, and once you have hauled a heavy case up a flight of cobbled Alfama steps you will understand why. A 40 litre bag, the largest most airlines allow in the cabin, comfortably holds a week of clothes if you pack in layers, plan to do a mid-trip wash, and choose pieces that mix and match. Roll rather than fold to save space, use a packing cube or two to stay organised, and wear your bulkiest items, the walking shoes and the warm layer, on the plane rather than packing them. The discipline pays off every single time you change towns.
Going carry-on also changes how you move through the country. You skip the baggage carousel, you can hop a CP train between Porto and Lisbon without wrestling a case down a narrow corridor, and you can walk the last few hundred metres to a guesthouse on a pedestrian street without resentment. For a longer or multi-region trip, the same principles still apply, just plan one more laundry stop. The point is not minimalism for its own sake; it is that Portugal is a country of stairs, cobbles, trams and tight old streets, and a light bag is the difference between gliding through them and fighting them.
Region by region: Algarve, Porto and the mountains
Different corners of Portugal ask for slightly different bags, so adjust at the margins once you know your route. The Algarve in the south is the closest thing to a conventional beach holiday: pack swimwear, sandals with grip for the rocky coves, the strongest sun protection you own, and light clothes, while still keeping one layer for the breezier evenings. The far west and the Costa Vicentina are windier and cooler than the sheltered central Algarve beaches, so a windproof layer earns its place even on a summer coast trip down there.
Porto and the north are greener and wetter, and that is no accident, because the rain is what feeds the Douro valley. A reliable waterproof and an extra warm layer matter more here than in the south, in any season. At the other extreme, the Serra da Estrela is mainland Portugal's high mountain range, where winters bring real snow and even summer nights are cold, so genuine cold-weather and waterproof gear is essential if your route climbs up there.
The lesson across all of it is the same one this guide keeps returning to: Portugal is not one climate but several stacked into a small country, so pack flexible layers and adjust for the specific corner you are heading to.
Why it matters
Why it matters: most disappointment on a Portugal trip is avoidable and traces back to the bag. Travellers who pack for an imagined heatwave end up cold on Atlantic evenings, soaked by a surprise shower, sliding on wet cobbles in the wrong shoes, or pickpocketed on a crowded tram. Getting the non-negotiables right, the grippy shoes, the layers, the sun cover, the zipped bag, and sorting the practical basics of plug, SIM, cash and transport card in advance, removes nearly every common friction point. Pack well for the coast and the cobbles, and the country itself does the rest of the work.
Practical tips
- Bring grippy, broken-in walking shoes above everything else; the calcada cobbles are slippery when wet and you will walk for hours.
- Pack a warm layer and a light rain shell in every season, because Atlantic evenings cool fast and showers arrive without warning.
- Carry a Type F plug adapter and a multi-port USB charger; the sockets are 230 volt Schuko, shared with most of Europe.
- Use a zipped crossbody bag worn at the front on trams and in markets, where opportunist pickpocketing is the main risk.
- Sort an eSIM or local SIM and pick up a Viva Viagem or Andante transport card on arrival, so your first day runs smoothly.
Local insight
Local insight: my packing rule for visitors is to pack as if every day will contain one hot hour, one cool hour and one wet hour, because in Portugal it usually does. That single mental image solves the layering problem on its own, and it stops people overpacking heat-only clothes they never wear. I also tell every friend to wear their walking shoes and warm layer on the plane, which frees up real space in a carry-on and means the two heaviest, most important items are already on their body if the bag goes missing. After thirteen years here, those two habits cover ninety percent of it.

Frequently Asked Questions
What should I pack for a trip to Portugal?
Lead with five non-negotiables: grippy, broken-in walking shoes for the slippery calcada cobbles, a light rain shell, a warm layer for cool Atlantic evenings, strong sun protection, and a zipped crossbody bag against pickpockets. Add a Type F plug adapter for the 230 volt sockets and sort a SIM or eSIM for data. Beyond that, pack flexible layers rather than heat-only clothes, keep outfits mix-and-match, and plan a mid-trip laundry so you can travel light. Adjust at the margins for your route, more sun gear for the Algarve, more waterproofs for Porto and the north.
What kind of plug and voltage does Portugal use?
Portugal uses the Type F plug, the round two-pin Schuko socket, at 230 volts and 50 hertz, the same standard as most of continental Europe. UK visitors need a simple adapter, and US and other non-European visitors need an adapter plus a check that each device handles 230 volts. Phones, laptops and most modern chargers are dual-voltage and fine; some hairdryers and small appliances are not, so check the label. A single multi-port USB plug adapter charges several devices at once and is one of the most useful small things to pack.
Do I need cash or are cards enough in Portugal?
Cards are enough for most of a trip. Contactless payment works almost everywhere, including many market stalls, so bring a contactless card with low foreign-transaction fees plus a backup card stored separately. That said, carry some cash too. Small village bakeries, a few traditional tascas, tips, church donations and the occasional rural cafe still prefer or only accept coins and notes. A modest amount of cash for the small and the rural, with cards for everything else, is the right balance and saves you being caught short at a counter.
How do I get a SIM card or data in Portugal?
You have three options. European visitors can roam at home rates under EU rules, which needs no action at all. Everyone else should consider an eSIM, which you buy and activate on your phone before you land, or a physical Portuguese SIM from MEO, NOS or Vodafone, sold cheaply at the airport and in phone shops. Data is inexpensive here. Having it from day one lets you use maps on rural roads, call a Bolt or Uber, and skip hunting for wifi, so sort connectivity before your first day rather than during it.
Can I do Portugal with just carry-on luggage?
Yes, and you should. A 40 litre cabin bag holds a week of clothes if you pack in layers, do a mid-trip wash, and choose mix-and-match pieces. Roll your clothes, use a packing cube, and wear your bulkiest items, the walking shoes and warm layer, on the plane. Going carry-on lets you hop trains between cities easily, skip the baggage carousel, and walk the last stretch to a guesthouse on a pedestrian street without dragging a heavy case. Given Portugal is a country of stairs and cobbles, a light bag is a genuine quality-of-life upgrade.
What shoes are best for walking in Portugal?
Grippy, broken-in walking shoes are the single most important thing you pack. The historic centres are paved in calcada portuguesa, polished limestone cobbles worn smooth over centuries that become genuinely slippery in even light rain, especially downhill. Smooth-soled city boots, fashion trainers and most sandals slide on it, and falls are common. Choose shoes with a real rubber grip and break them in at home so they do not blister you on the long days, since you can easily cover ten kilometres a day across hills in Lisbon or Porto. Comfort beats style here every time.
How do I avoid pickpockets in Portugal?
Portugal is a safe country, so the realistic risk is petty theft rather than danger. Opportunist pickpocketing concentrates in crowded trams, especially Lisbon's number 28, busy stations, packed viewpoints and tourist markets. The best defence is a zipped crossbody bag worn across the front of your body, keeping phone and wallet where you can feel them. Avoid back pockets, do not wear a backpack on your back in a crowd, split your cash and cards between two places, and stay alert near tram doors where the pushing happens. These small habits keep the one common annoyance from ever touching your trip.
