Barcelona has 14 municipal outdoor swimming pools and choosing the wrong one — the most expensive when you’re budget-conscious, the most crowded when you want quiet, the shallowest when you’re an adult swimmer — is the mistake most visitors make. Prices range from €2.75 (Llac de la Creueta del Coll) to €18.29 (Bernat Picornell). One is completely free and uses saltwater. All function as climate refuges during heatwaves, and all have recirculation systems that allow operation during drought periods.
The season opens in June with the first 4–5 facilities and fills to 14 by midsummer. It closes progressively in September, with some facilities — Bernat Picornell, Sant Sebastià — open almost year-round.
How much do Barcelona’s outdoor pools cost? From €2.75 (Llac de la Creueta del Coll, cheapest) to €18.29 (Bernat Picornell, Olympic pool). The Montjuïc pool is €7.55 general entry. The Banys del Fòrum are free. All have reduced rates for under-15s, over-65s and Targeta Rosa cardholders. Season runs June to September at most facilities.
Quick decision: which pool for which profile?
- Most visual experience in Barcelona → Piscina Municipal de Montjuïc — €7.55 adults, city skyline views, 2,520 m² sunbathing area, the most photographed pool in the network

- Children under 6 → CEM Can Dragó or Llac de la Creueta del Coll — minimum depths designed for early childhood, differentiated zones, reduced prices
Piscina de Montjuïc: why it’s the most recognised
The Piscina Municipal de Montjuïc (Av. Miramar, 31) is the most photographed pool in Barcelona for a technical reason: the diving platform has the city skyline as its visual backdrop. This produced the most-reproduced images from the 1992 Olympic facilities and has made the space a regular set for music videos, advertising and audiovisual productions.
Prices: €7.55 adults, €5.23 reduced (under-15s and over-65s). Hours: Monday–Thursday 11am–7pm; Friday, Saturday, Sunday and holidays 11am–8:30pm. Season: 7 June to 7 September.
What most guides don’t include: there are no swimming lanes. The pool basin is designed for leisure use and the sunbathing terrace — 2,520 m² — is the functional centrepiece of the facility. For anyone who wants to swim continuously, Bernat Picornell is 10 minutes’ walk away with the technical infrastructure the Montjuïc pool lacks. For the panoramic Montjuïc views without paying pool entry, the castle gardens and the MNAC terraces both have viewpoints at no cost.
Banys del Fòrum: the free saltwater pool nobody mentions
The Banys del Fòrum (Plaça del Fòrum, 1, Sant Martí) are the most overlooked facility in the entire network: free entry, seawater and accessible for reduced mobility. It’s not a conventional pool — it’s an urban bathing zone built with concrete platforms and steps down to the sea, without sand. The format is similar to some Greek island bathing coves.
Operating season: July and August, 11am–2pm. The restricted hours deliberately manage capacity to maintain orderly access. The platform surface reaches very high temperatures: it’s the only facility in the network where water shoes are practically obligatory.
For anyone visiting Poblenou or the 22@ district during the day, the Banys del Fòrum are the most efficient end-of-day option: no cost, real Mediterranean seawater.
Can Dragó and Creueta del Coll: the two family extremes
CEM Can Dragó (Passeig d’Andreu Nin, 50, Nou Barris) is Barcelona’s largest pool. The 15,000 m² aquatic leisure area includes an artificial lake with depths ranging from 10 cm to 1.30m — the widest safety range in the network for children of different ages. Prices: €9.60 adults, €6.55 for ages 6–14, €6.55 Targeta Rosa, €2.70 ages 0–5. The scale allows high user density without a sense of saturation.
Llac de la Creueta del Coll (Pg. Mare de Déu del Coll, 77, Gràcia) is the cheapest in the network: €2.75 adults, free for over-65s, €1.27 for large and single-parent families. The 10-session pass costs €20.68. Maximum depth is 60 cm throughout — which makes it the safest space for children aged 2–6, but limits use for adult swimmers. It’s a former quarry converted into a park with an artificial lake in Gràcia.
Bernat Picornell: the only Olympic pool open to the public
Piscines Bernat Picornell (Av. de l’Estadi, 30-40, Montjuïc) is the most technically complete facility in the network. A 50-metre outdoor Olympic pool designed for the 1992 Games by Antoni de Moragas. The outdoor pool opens late June to 11 September; the indoor pools function year-round.
Summer outdoor entry: €18.29 adults, €10.99 Targeta Rosa. The highest price in the network. The justification is the technical infrastructure: numbered lanes, consistent depth, filtration systems certified for continuous lap swimming.
What no tourist guide mentions: Bernat Picornell runs nudist bathing sessions. On Saturday nights and Sunday afternoons in winter, the indoor pools operate dedicated nudist sessions. This is a regular programme with a stable user community — not an occasional event.
CEM Sant Sebastià: open almost year-round with sea views
CEM Sant Sebastià (Plaça del Mar, 1, Barceloneta) has the most competitive location in the network: outdoor pool on the beachfront, with the Mediterranean metres away. Open almost year-round, at €14.08 for adults with reduced rates for over-65s and Targeta Rosa.
For visitors to La Barceloneta who want to alternate pool and sea swimming in the same day, this is the most efficient combination in the network. The Sant Sebastià beach is immediately adjacent.

What most guides miss: the Banys del Fòrum water shoe requirement
Every guide that mentions the Banys del Fòrum describes them as “free saltwater pool.” Almost none mentions that the concrete platform surface reaches temperatures that make walking without water shoes genuinely painful during summer afternoons — or that the platform design means there’s no shade anywhere during peak hours.
The Banys del Fòrum are the best free bathing option in Barcelona and the most honest alternative to the commercial beach bars. But they work best arrived at around 11am when they open, with water shoes and sun protection, and left before the platform gets dangerously hot at midday. That’s the operational knowledge that makes the free option actually good.
Do Barcelona’s municipal pools require advance booking?
Most facilities allow direct access without booking, but in peak season (July–August) the hottest days can see facilities reach maximum capacity before midday. Can Dragó and the Montjuïc pool are the most frequently saturated at weekends. Some facilities have online ticket purchase systems that secure entry and avoid queue time at the ticket desk. Bernat Picornell and CEM Sant Sebastià both have digital platforms.
Which pools are open year-round?
Bernat Picornell (indoor pools year-round, outdoor June–September) and CEM Sant Sebastià (outdoor pool almost year-round with reduced winter hours) have the longest operational continuity. CEM Parc de la Ciutadella runs a longer season than average: approximately 17 April to 31 October.
Best option for children under 4?
Banys del Fòrum is the most mobility-accessible facility in the network — no steps to the water, ramps, free entry. Can Dragó has gradual-entry ramps with tactile signage on the lake edges. CEM Guinardó recently renovated its access ramp. Facilities with higher pool edge heights — like Bernat Picornell — have hydraulic chair lifts at the main pools.
Who is this for?
Budget travellers in summer → Llac de la Creueta del Coll at €2.75 or Banys del Fòrum for free — both cover the essential function at the lowest possible cost
Families with mixed-age children → CEM Can Dragó — the 10 cm to 1.30m depth range is the only facility that accommodates toddlers and older children in the same space without the risk that comes from uniform-depth pools
Serious swimmers → Bernat Picornell — the only Olympic-length outdoor pool in the network; the €18.29 entry is the price of proper lane infrastructure
Visitors wanting the Barcelona experience → Piscina de Montjuïc at €7.55 — the skyline view from the sunbathing terrace is real and the facility works well as a half-day destination combined with other Montjuïc sights
Mistakes to avoid
- Going to the Montjuïc pool expecting to swim laps — there are no lanes; it’s a leisure pool; Bernat Picornell is 10 minutes away if swimming is the priority
- Arriving at the Banys del Fòrum without water shoes — concrete platforms in direct sun in August; the one essential piece of kit for this specific facility
- Going to Can Dragó or Montjuïc on a peak August Saturday afternoon — both reach capacity before midday on the hottest days; mornings or weekdays are completely different experiences
- Not checking Bernat Picornell’s nudist schedule before booking — if the indoor pool is the winter destination, the Saturday night and Sunday afternoon nudist sessions affect availability for general swimming
The price gap between the Creueta del Coll (€2.75) and Bernat Picornell (€18.29) is €15.54 — enough for six more sessions at the cheapest pool in the city. The decision isn’t about price. It’s about what you want to do: lane swimming means Bernat Picornell; a day with children without spending much means Creueta del Coll; the visual Barcelona experience means Montjuïc; free saltwater means Banys del Fòrum. The network covers all four, which is the point.
For planning the full day around whichever pool you choose, the Barceloneta guide covers the waterfront zone for anyone combining pool and beach. And for the Montjuïc complete guide covering what else is on the hill beyond the pool, the guide integrates all the Montjuïc attractions into a single day plan.
