There's a moment every Valencian summer — usually right about now, mid-July, when the Feria is in full swing and the asphalt starts radiating heat at midnight — when the beach stops being the answer. The sea is 27 degrees and feels like soup. The solution is inland: the provinces of Valencia and Castellón are full of piscinas naturales — river pools, gorges and waterfalls where the water stays cold all summer. Most are under 90 minutes from the city. Here are the seven that locals actually use, with the practical details nobody tells you.
1. Montanejos — the thermal classic
The famous one, and it earns it. The Fuente de los Baños in Montanejos (Alto Mijares, Castellón) is a thermal spring where the water comes out at a constant 25°C all year — warm enough in winter, refreshingly cool against a 38°C July afternoon. The setting is a turquoise river running through a limestone canyon, with cliff walls that jumpers have been launching off for generations (watch the locals before you try; depths vary).
Getting there: about 1h15 by car via the A-23 towards Teruel, exit at Montán. There's also a Herca bus from Valencia's bus station a few times a week in summer — check the current timetable, it changes. Parking in July fills by 11am; the village charges a few euros for the main lots. Go early or go late afternoon.
Local tip: walk 15 minutes upriver past the main pool and the crowds thin dramatically. Bring water shoes — the riverbed is stones, not sand.
2. Chulilla — the Charco Azul and the hanging bridges
Chulilla, about 60km northwest of Valencia, is best known for the Ruta de los Puentes Colgantes — a spectacular walk through the Turia gorge over two hanging bridges. The swimming reward is the Charco Azul, a deep blue pool in the canyon reached by a separate short trail from the village. Cold, clear, surrounded by rock walls that climbers use as one of Spain's best sport-climbing areas.
Getting there: 50 minutes by car via the CV-35. No useful public transport — this one needs wheels or a shared ride. Do the bridges route in the morning (it's exposed and brutal after noon in July), swim after, then a menú in the village. The trail to the Charco can close in high fire-risk periods, so check the Chulilla town hall's alerts before driving out.
3. Anna — the lake and the Gorgo
Anna, in the Canal de Navarrés about 50 minutes south, has two acts. The Albufera de Anna is a spring-fed lake ringed by lawns and picnic tables — it's managed, there's an entry fee in summer (a few euros), and it's the easy family option. The wilder act is the Gorgo de la Escalera: 136 stone steps down into a gorge where waterfalls drop into a cold green pool. The climb back up in July heat is the price of admission.
Getting there: car via the A-7/CV-40. Weekends in July get busy — Valencians know this place well. Arrive before 11 or after 5.
4. Bolbaite — the waterfall curtain
Ten minutes from Anna, the river Sellent drops over a wide curtain of waterfalls right at the edge of Bolbaite village. The pool below is broad and shallow at the edges, deeper in the middle, and the falls give you a free hydromassage. In recent summers the town has regulated access with paid parking and capacity limits on peak days — worth checking their site or calling ahead on a July weekend. Combine Anna and Bolbaite into one day; that's the standard local move.
5. Navajas — the Salto de la Novia
The Salto de la Novia in Navajas (Alto Palancia) is a 30-metre waterfall on the river Palancia with a swimming area below, wrapped in poplars and legend — the name comes from a bride who supposedly leapt the river for luck. It's one of the few swimming holes you can reach by train: the Cercanías C-5 from Valencia Nord towards Caudiel stops at Navajas, and the falls are a 20-minute walk from the station. That makes it the best no-car option on this list.
Local tip: Navajas village itself, with its modernist summer villas, is worth a wander — and Segorbe, one stop away, does a serious menú del día.
6. Chelva — the Ruta del Agua and the Playeta
Chelva's Ruta del Agua is a circular walk that threads through tunnels, an ancient aqueduct and the river Chelva, passing several swimmable pools — the main one, La Playeta, is right below the village with easy access and shade. The full loop takes about two hours; in July, do it early and plan to be in the water by noon. About 1h10 by car on the CV-35, past Chulilla.
7. Cueva Turche, Buñol — the amphitheatre
Twenty minutes closer than everything else on this list: the Cueva Turche near Buñol (yes, the Tomatina town) is a 60-metre cliff amphitheatre with a waterfall that runs strongest in spring and a big green pool at its base. Forty minutes by car from Valencia, and Buñol is also on the Cercanías C-3 line — from the station it's about an hour's walk or a short taxi. Because it's the closest, it's also the busiest; midweek visits are dramatically better.
The practical stuff
What to bring: water shoes (every single one of these has a stone bottom), cash for parking and village bars, a cooler if you're driving — and take every scrap of rubbish back out. Several of these towns have started restricting access precisely because of litter.
What not to do: don't jump from rocks without watching locals first, don't bring glass, and don't count on shade — a cheap umbrella earns its keep. Soap and shampoo in the river are both illegal and gross.
When to go: July and August weekends are peak everything. If you can only go on a Saturday, leave Valencia by 9am. Better: take advantage of Valencia's summer Fridays and go midweek — you'll have pools to yourself that on Sunday hold two hundred people.
And if you can't leave the city at all this week? The public pools guide and the beach guide have you covered — and there's always an horchata with your name on it.
