A week of warm Atlantic light, cliffs the colour of ginger biscuits and a supermarket trolley full of custard tarts — the Algarve is still one of the cheapest places in Europe to take children to the sea. The trick is knowing which weeks to fly, which resorts to skip, and where the free stuff is.
The short version: what "under £500" actually buys
Let's be precise, because "family holiday for under £500" gets thrown around loosely. For a family of four travelling in shoulder season (late April to mid-June, or the second half of September into October), the two big-ticket items — flights and a self-catering base — can genuinely land under £500 combined.
- Budget airline flight from London to Faro (return): from £28 per person
- Budget airline flight from Manchester to Faro (return): from £21 per person
- Self-catering apartment in Albufeira (7 nights): estimated £280–£450 (estimate — not verified against live prices)
- Family-friendly apartment in Lagos (7 nights): estimated £300–£480 (estimate — not verified against live prices)
Four Manchester fares at the low end plus a mid-range Albufeira apartment gets you a holiday shell for roughly £364 before you've eaten a single grilled sardine. From London the maths still works. What it will not cover is August, a sea-view balcony, a hire car for seven days and three restaurant dinners. Those are choices, and this guide is about which ones to make.
Timing: the single decision that saves the most money
Algarve pricing is brutally seasonal. The same apartment that costs a few hundred pounds in early May can quadruple in the second week of August. School holidays are non-negotiable for many families, but there is nuance worth exploiting:
- Late May half-term is warm enough to swim (the Atlantic hovers around 18–19°C — bracing, but children barely notice) and prices sit well below July.
- The last week of the summer holidays is usually cheaper than the first two, because the market has already emptied.
- October half-term is the underrated one: still 22–24°C in the afternoons, half-empty beaches, and accommodation at spring rates. Pack a fleece for the evenings.
- Tuesday and Wednesday departures from UK regional airports routinely undercut Friday and Saturday by a meaningful margin.
On booking windows: budget airline fares to Faro tend to be at their lowest roughly eight to twelve weeks out for shoulder season, and much earlier — six to nine months — for peak summer. Apartments behave differently. Owners in Albufeira, Alvor and Lagos often drop rates three to four weeks before an unsold week, so if you have flexible dates and a free-cancellation reservation held as insurance, late looking pays.

For accommodation, the free-cancellation trick is the whole strategy: reserve a refundable apartment early to lock in a ceiling, then re-check the same dates monthly and rebook if the price falls. Compare Algarve apartments and free-cancellation rates on Booking.com and filter for "kitchen", "washing machine" and "free cancellation" before you look at anything else.
Where to base yourself — and the resorts to think twice about
Your base decides your budget more than any other single factor, because it determines whether you need a car.
Albufeira (Old Town or Oura, not The Strip)
The cheapest apartment stock in the Algarve, an airport bus that runs directly from Faro, and half a dozen beaches within a pram-push. Stay in the Old Town for whitewashed lanes and the lift down to Praia dos Pescadores; avoid the Areias de São João strip unless you enjoy 2am karaoke.
Lagos
Prettier, walkable, with the enormous flat sands of Meia Praia on one side and the sculpted coves of Ponta da Piedade on the other. Slightly pricier than Albufeira, but it sits on the regional railway line, which makes car-free days out genuinely easy.
Alvor and Armação de Pêra
Quieter, more Portuguese, with river estuaries and shallow lagoons that suit toddlers. Fewer flights of steps, fewer English breakfasts, better value on food.
Where costs creep up
Vilamoura, Quinta do Lago and Praia da Luz are lovely and expensive. Carvoeiro is beautiful but built on a hill, which matters more than you think with a buggy and a cool bag.
A beach for every mood (all of them free)
Every beach in Portugal is public. Sunloungers cost money; sand does not. Bring a windbreak-free approach: a cheap parasol from the local Chinese bazaar shop costs less than a single day's lounger hire and comes home with you.
- Praia da Falésia — three miles of ochre cliffs and firm, flat sand. Best for long walks and older children who like running until they fall over.
- Meia Praia, Lagos — shallow, wide, and calm at the town end. The easiest beach in the region for under-fives.
- Praia dos Salgados — backed by a lagoon full of flamingos and storks; a free wildlife lesson between swims.
- Praia dos Pescadores, Albufeira — fishing boats hauled up on the sand, a lift down from the Old Town, and the best people-watching in the Algarve.
- Praia da Marinha — the postcard one. Steep steps, so go early, and hold hands on the descent.
- Praia Grande, Ferragudo — sheltered, family-run cafés, and calm water that suits nervous swimmers.
Our own favourite hour of the whole week cost nothing at all. At Praia dos Pescadores just before seven, the sand still held the day's heat, the loudspeaker from the boat-trip kiosk had gone quiet, and the smell of charcoal and sardine skin was drifting down from the Old Town. Our youngest had found a hollow in the wet sand where a wave kept refilling a rock pool, and she stood there for forty minutes, counting the refills out loud, while the cliffs behind her turned from apricot to bruise-purple. No ticket, no queue, no ice cream required — although one was eventually negotiated.
Free and nearly-free days out
- Silves castle and the old Moorish town — a red sandstone fort with proper battlements, for the price of a couple of coffees.
- Ria Formosa boardwalks at Quinta do Lago or Faro — salt marsh, chameleons if you're lucky, no entry fee.
- Ponta da Piedade — walk the clifftop path above Lagos; the views cost nothing and the boat trip below is optional.
- Cabo de São Vicente — the end of Europe, an enormous lighthouse and a chorizo-in-a-roll van. Windy and free.
- Municipal markets — Loulé, Olhão and Portimão. Fish, figs, honey and a proper sense of place for the cost of lunch.
- Municipal pools and skate parks — Lagos, Portimão and Albufeira all have them, and they cost a fraction of a waterpark ticket.
If you want one paid activity, make it a boat. Benagil Cave trips and dolphin-watching sailings run from Portimão, Lagos, Albufeira and Armação de Pêra, and small kayak or RIB operators booked directly at the harbour kiosk are usually cheaper than the big packaged versions. Compare the harbour price against online activity marketplaces such as GetYourGuide before you commit — for a family of four, the difference can be the price of two dinners. Note that many operators set a minimum age for cave RIBs, so check before you queue.
Eating well without eating the budget
This is where the Algarve quietly rewards you. A few rules that worked for us:
- Book self-catering with a real kitchen. Breakfast and one other meal at home, made from Pingo Doce or Continente supplies, roughly halves a family food bill.
- Hunt the prato do dia. Weekday lunch specials in inland or backstreet restaurants — soup, main, bread, sometimes a glass of wine — are the best value meal in the country.
- Say no to the couvert if you don't want it. The bread, olives and paté brought unasked to your table are chargeable. Waving them away is normal and nobody minds.
- Share. Portuguese portions, particularly grilled chicken and cataplana, comfortably feed two adults or one adult and two children.
- Drink the local stuff. A jug of house wine and a bottle of Luso water cost less than two imported soft drinks on the strip.
Getting around: do you actually need a car?
If you're staying in Albufeira or Lagos and plan to spend most days on one or two beaches, probably not. The airport express bus from Faro to Albufeira, the Vamus regional network and the Algarve railway line between Faro, Albufeira, Portimão and Lagos are inexpensive and reliable enough for day trips. Trains are slow and scenic; children generally consider this an improvement.
Hire a car if you want Sagres, Monchique, the eastern islands and the empty west coast. Book it well in advance, choose an off-airport supplier only if their shuttle is quick, and take a full-to-full fuel policy. If you'd rather not pay for the hire company's own excess waiver at the desk, standalone car hire excess insurance from a UK provider is dramatically cheaper — buy it before you fly.
Speaking of insurance: single-trip travel cover for a family is often only a few pounds more than solo cover, and annual multi-trip policies from providers such as Coverwise pay for themselves in two holidays. Whatever you buy, buy it the day you book the flights, not the week you leave — cancellation cover only works if it exists before something goes wrong.
When the budget airline lets you down
Cheap fares and tight turnarounds go together, and Faro is a delay-prone airport in peak season. UK and EU rules mean that if your flight is delayed more than three hours or cancelled at short notice, and the cause is within the airline's control, you may be owed cash compensation on top of any refund — per passenger, children included. Airlines rarely volunteer this.
Keep your boarding passes and any delay notification, and if you'd rather not fight the claim yourself, check your delayed-flight claim with AirAdvisor — they work on a no-win, no-fee basis. For a family of four, a successful claim can be worth more than the flights themselves.
A workable seven-day shape
| Day | Plan | Rough spend |
|---|---|---|
| 1 | Arrive, airport bus, supermarket shop, apartment picnic supper | Groceries only |
| 2 | Local beach all day; ice creams at five | Under €10 |
| 3 | Train to Silves; castle, market, riverside lunch | Low |
| 4 | Boat trip to the Benagil coastline (the one paid splurge) | Main activity cost |
| 5 | Praia da Falésia or Meia Praia; prato do dia lunch inland | Low |
| 6 | Ria Formosa boardwalks or Ponta da Piedade clifftop walk | Free |
| 7 | Market morning, last swim, grilled chicken supper | Modest |
Note what's missing: a waterpark. Slide and Splash and Zoomarine are genuinely good, but a family day out at either can cost more than three nights of your apartment. If it's the thing your children will remember, budget for it deliberately and cut a restaurant meal or two. If it isn't, the sea is free.
Five mistakes that quietly break the budget
- Paying for hold luggage you don't need. Four sets of beach clothes fit in cabin bags. Buy sun cream, buckets and spades at the Portuguese supermarket.
- Booking an airport transfer before checking the bus. The Faro airport express to Albufeira costs a fraction of a private transfer for four.
- Choosing accommodation by photo rather than by kitchen. A "kitchenette" with two hobs and no oven changes how you eat all week.
- Eating on the main strip every night. Walk three streets inland; prices drop by a third and the food improves.
- Leaving travel insurance to the airport. It's the most expensive place in Britain to buy it.
Once you've settled on dates, the last job is locking in the apartment. Check current Albufeira and Lagos apartment prices for your week, and set a reminder to re-check a month before you fly.
Frequently asked questions
Is the Algarve cheaper than Spain for a family beach holiday?
Broadly, yes — accommodation and eating out are typically cheaper than the Costa del Sol or the Balearics, particularly outside July and August. Flights are usually comparable. The main saving is at the restaurant table.
When is the cheapest time to fly to Faro from the UK?
Mid-week departures in late April to early June, and from mid-September through October, deliver the lowest fares. Live examples include a budget airline flight from London to Faro (return) from £28 and a budget airline flight from Manchester to Faro (return) from £21.
Is the sea warm enough for children in May and October?
The central Algarve sea sits around 18–19°C in May and 20–21°C in October. Adults find it sharp on entry; most children are unbothered after ninety seconds. Sheltered spots such as Alvor and Ferragudo warm up faster than the open Atlantic beaches.
Do we need a hire car with young children?
Not if you base yourself in Albufeira, Lagos or Alvor and use the beaches and buses on your doorstep. Hire a car for two or three days mid-trip if you want Sagres, Monchique or the west coast, rather than paying for a full week you'll leave parked.
How much spending money should we budget per day?
Families who self-cater breakfast and one other meal typically manage on a modest daily food and activity budget, with the exception of any paid excursion or waterpark day. Build one splurge into the week and keep the rest simple.
Which Algarve beach is best for toddlers?
Meia Praia in Lagos at the town end, or the estuary side of Alvor — both are wide, shallow and shelve gently, with facilities close to the sand.
