September is one of the best Algarve months: the sea is at its warmest and the school-holiday crowds have gone.
The coast is all cliffs, coves and steps, so pack shoes that grip as well as sandals.

Karen’s tipWeather changes fastLayer it up
Three thin layers from your capsule beat one thick coat in Algarve in September: add or peel them off as the day changes.
- Base · next to skin
- Vest
- Mid · warmth
- Shirt dress or linen shirt
- Outer · wind and rain
- Light knit
☀ When it warms up: Day: swimwear and shirt. After sunset: knit on.
🎒 Stash it: Knit in the beach bag.

Karen’s tip On the plane
- Wear your heaviest items on travel day: your bulkiest shoes and any layers. They’d take the most space and weight in your bag.
- Too hot for a jacket? Skip the jacket and take a neutral-colour wrap or pashmina. It keeps you warm on the plane and doubles as an evening wrap and as 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 tipChange 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.

What’s underfoot
The ground
- Sandstone cliff paths
- Long beach staircases
- Portuguese mosaic pavements (calçada), slippery when wet
- Cobbled old towns
12,000-18,000 stepseditorial estimate
Trouble spots
- Ponta da Piedade steps (about 180-200)
- Benagil cave: boat or guided kayak only, no landing on the beach
- Praia do Camilo land staircase reported closed (2026)
☀ Day shoes
Trainers with grip for cliff walks; strapped sandals for beaches.
☾ Evening shoes
Flat sandals with grippy soles.
✕ Leave at home
Smooth soles on calçada; flip-flops on cliff paths.
Season notes: Dry in September; calçada is slippery after the first autumn rains.
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.

The 10 kg cabin bag packing list
Your bag: 55 × 40 × 20 cm
Planned for 7 nights with a paid 10 kg cabin bag (55 × 40 × 20 cm, Ryanair’s size) plus the free under-seat bag. The rule that makes it work: wear your bulkiest items on the plane.
Wear on the plane worn
In the bag 11 items
Karen’s tipRoll, don’t fold. I roll my clothes, stuff socks and small bits inside my shoes, and keep socks in a clear bag that comes home full of dirty laundry or wet swimming costumes. How I pack →
Karen’s tipPack a bag in a bag.A foldable shopping bag that folds into its own little pouch, for shopping, dirty laundry and pool towels. It saves buying a bag abroad.Why, and where to get one →
- Big sun cream (buy at Continente)
- Heels (cobbles and cliffs)
Karen’s tipLeave the towel at home. “I use the towels in my room, and hotels usually offer pool towels too, sometimes for a small refundable deposit. Worst case, I buy a cheap towel locally and leave it behind.”
Liquids: going vs coming home
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.
- 100 mlFaro (FAO), 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: Faro 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 →
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
- Beach gear: umbrella, loungers
Here: Hotels usually have hairdryers; villas and apartments vary.
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 supermarkets: own-brand SPF50 is very cheap.
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).
Flying there on Ryanair, easyJet or Wizz?
- A week of beachwear fits in one 10 kg cabin bag (Jet2 and TUI include one; on Ryanair it’s Priority & 2 Cabin Bags, on easyJet a large cabin bag) plus a free under-seat bag.
- Couples: one 10 kg cabin bag each, and share one under-seat bag for sun cream, chargers and documents. Or book a single 15 kg hold bag between you and both travel with just the free bag: compare the prices for your dates.
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.
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.

Entry and practicalities
Entry requirements
Schengen 90/180; EES.
Share the load
- one 10 kg cabin bag each, and share one under-seat bag for sun cream, chargers and documents. Or book a single 15 kg hold bag between you and both travel with just the free bag: compare the prices for your dates.
- 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.
