What to wear in Lisbon in May, in a free under-seat bag

Seven hills and shiny stone pavements. Grippy trainers do all the work; a light jacket covers windy viewpoints.

22.1 °C (72 °F) avg high13.9 °C (57 °F) avg low Fits a 40 × 30 × 20 cm free bag Planned for 4 nights

May in Lisbon is warm, bright and not yet hot. Days are for climbing hills to viewpoints, evenings for Alfama and Bairro Alto.

Lisbon’s famous mosaic pavements (calçada portuguesa) are beautiful and polished smooth: your sole matters more than your heel.

Base · next to skin
Tee
Mid · warmth
Shirt or light knit

Karen’s tip

On the plane

  • Wear your heaviest items on travel day: coat, knit and your bulkiest shoes. They’d take the most space and weight in your bag.
  • Planes can be cold with the air con, so take a jacket on board.
  • Pack a neutral wrap or pashmina too: it doubles as an evening wrap and a shoulder cover for churches here.
  • An inflatable cushion that packs into its own small, discreet pouch: a head cushion on the flight and a pillow on beach sunbeds. You choose how much air goes in, so it’s as firm or soft as you like, which a foam neck pillow can’t do.

Karen’s tip

Change your hair, change the look

Swapping my hair from up in the day to down in the evening (or the other way round) gives the whole outfit a different look. Even one piece of jewellery I didn’t wear earlier does the same.

💡 It’s a free trick, and it saves packing extra outfits.

Terrain and footwear

What’s underfoot

The ground

  • Steep hills (seven of them)
  • Polished limestone mosaic pavements (calçada portuguesa), slippery when wet
  • Cobbles and stairs in Alfama

15,000-20,000 steps with lots of climbingeditorial estimate

Trouble spots

  • Alfama stairways
  • Wet calçada after rain
  • Steep Bairro Alto lanes

☀ Day shoes

Trainers with grippy rubber soles.

☾ Evening shoes

Rubber-soled loafers, flats or low block-heel boots.

✕ Leave at home

Stilettos, smooth leather soles.

Season notes: May showers make calçada slick.

Karen’s tipHeels and cobbles don’t mix. Check the ground before you pack heels: thin heels catch between cobbles, so a wedge or block heel is steadier for evenings.

One pair, day to night: The best space-savers are a sleek waterproof leather ankle boot (Paris, London, Vienna & Prague, Amsterdam, Rome in December), a clean minimalist leather trainer or slip-on loafer (Tokyo, London), and a low block-heel sandal (cruise). Travel day: wear the heavier pair (see On the plane). Break in shoes before the trip.

Liquids: going vs coming home

Going (from the UK)

UK airports vary. Heathrow, Gatwick, Birmingham, Bristol, Edinburgh, Belfast International, Belfast City, Bournemouth, Southend allow containers up to 2 litres; most others, including Manchester, Stansted and Luton, are still 100 ml.

Flying home from Lisbon
  • 100 mlLisbon (LIS), in a 1 L clear bag

Pack your liquids to 100 ml for the whole trip.

Pack every liquid in 100 ml bottles inside a 1 litre clear bag, so the same pouch works on both legs. Travelling as a couple, each of you gets your own 1 litre bag, so split the toiletries.

Karen’s tipWater bottle: keep it full through a 2-litre UK airport, or take it empty through a 100 ml one. Flying home: Lisbon is 100 ml, so empty it and refill airside.Check your airport →

Karen’s tipDecant, don’t buy mini. I decant sun tan lotion into clear 100 ml spray bottles, and my day cream, night cream and cleanser into one squashy three-section silicone pot for trips of up to 4–5 days (separate pots if longer). Far cheaper than minis. How to do it →

Liquids rules by airport, with sources →

Karen’s tip

Check your room first

Read the hotel, Airbnb or hostel listing, or message the host, and ask whether they provide:

  • Iron or steamer
  • Hairdryer
  • Toiletries: shampoo, shower gel (conditioner often isn’t supplied)
  • Towels, plus beach or pool towels
  • Washing machine or laundry service
  • Plug adapters or USB sockets
  • Kettle, tea and coffee
  • Slippers and a robe
  • A safe

Here: Hotels usually have a hairdryer; apartments vary. Kettles are uncommon.

Hostels often don’t provide towels or padlocks.

Karen’s tip Bring your own hair products. Most hotels supply shampoo but often not conditioner. Decant favourites into leak-proof travel bottles under 100 ml (fill them about ¾ full), or switch to solid bars, which don’t count as liquids. Amazon UK: Lericttor 100ml Silicone Travel Bottles ↗Check price · Amazon UK: Friendly Soap Travel Bar 95g (hair & body) ↗£4.72, price checked 20 Oct 2026

Every item they provide is one you don’t carry.

Karen’s tip

No-iron packing

Pick fabrics that don’t crease. Woven cotton and linen crease; knits, merino, jersey and most polyester blends barely do.

  • Hang creased clothes in the bathroom while you shower.
  • Pack a small crease-release spray under 100 ml (it counts as a liquid).
  • Roll clothes, and keep crease-prone pieces in a packing cube on top, not in a vacuum bag.
  • Check whether your hotel or Airbnb has an iron.

Karen’s tip

Buy it there?

Adding a checked bag typically costs around £60–80 return on a budget airline. So if your bag is full, buying bulky or liquid items when you arrive is often cheaper.

Think sun cream, full-size shampoo, insect repellent, a beach towel or flip-flops.

Yes, cheaper than the UK in this destination: Continente and Pingo Doce sell everyday toiletries at below UK prices.

More on buying it there →

Tick items off as you pack (your ticks aren’t saved). Liquids rules depend on your departure airport and change from time to time. Check your airport’s current security rules before you decant your toiletries (see liquids rules by airport).

Free baggage check

Flying there on Ryanair, easyJet or Wizz?

  • Free under-seat bag only (Ryanair, Wizz, Vueling, Jet2’s under-seat bag: 40 x 30 x 20 cm; easyJet 45 x 36 x 20 cm): this list fits a 24-28 L backpack if you wear the bulkiest pieces.
  • Couples on free bags only: one person carries the shared toiletries and chargers, the other the shoes. If one of you buys a 10 kg cabin bag, both of you can travel with a free under-seat bag each and share the big one.

Duty-free bag: Buying at the airport? On Ryanair, Wizz, Transavia, Norwegian and easyJet one shop bag can usually go on board on top of your bag; on Jet2, BA, Aer Lingus, Vueling and Lufthansa it has to fit inside your allowance. Gate staff decide, so keep it small. Duty free and your free baggage →

Sizes come from each airline’s official page (see our free baggage reference for links). Rules change, so check your booking before you fly.

Sized for free baggage

Baggage picks

The ticks compare each bag’s stated outer dimensions with each airline’s free-bag size. A struck-through name means the bag is too big for that airline. Soft bags squash a little; hard cases don’t. We haven’t tested these bags ourselves yet.

Travelling as a couple

Share the load

  • Couples on free bags only: one person carries the shared toiletries and chargers, the other the shoes. If one of you buys a 10 kg cabin bag, both of you can travel with a free under-seat bag each and share the big one.
  • Pack every liquid in 100 ml bottles inside a 1 litre clear bag, so the same pouch works on both legs. Travelling as a couple, each of you gets your own 1 litre bag, so split the toiletries.
  • Share one set of chargers, adaptor and toiletries; each of you still gets your own liquids bag allowance.
  • Split each person’s outfits across both bags, so a gate-checked bag doesn’t leave one of you with nothing.
