El Choyín: La Fortuna's Free Hot River

The hot river nobody sells you a ticket for

Every hot springs list for La Fortuna eventually gets to the same line: “and there’s a free one too.” That’s El Choyín, sometimes spelled Chollín, a stretch of naturally warm river that runs under a road bridge a short drive from the town centre, close to Tabacón. The water is heated the same way every paid pool in the valley is heated — by runoff and groundwater warmed by geothermal activity around Arenal — the difference is that nobody built a resort around this particular stretch. There’s no gate, no wristband, no changing room, and no fee.

That’s genuinely appealing after a few days of paying admission at every stop. It’s also the reason this page exists on its own, separate from the comparison of the paid hot springs complexes: El Choyín isn’t a cheaper version of Tabacón or Baldi. It’s a different kind of place entirely, with a different set of trade-offs, and treating it like a free pool with the staff missing is how people end up disappointed, soaked to the bone in a downpour with no shelter, or short a phone.

This guide covers what El Choyín actually is, how to get there, what “no supervision” really means in practice, and what to do with the things you’d normally hand to a locker attendant.

Where El Choyín is, and how to find it

El Choyín sits on the road that runs from La Fortuna town centre out toward Tabacón and the volcano — the same corridor most hot springs resorts and several things-to-do around the volcano are strung along. The river crosses under a bridge, and a rough pull-off area on the roadside is where cars park. There’s no sign pointing tourists in, and no formal parking lot — just a shoulder wide enough for a line of cars, which fills up on weekends and empties out on weekday mornings.

If you’re self-driving, punch “El Choyín” or “Chollín” into your map app rather than trying to describe it to anyone — the two spellings both resolve to the same spot, and locals use them interchangeably. If you don’t have a rental car, this is one of the harder free attractions to reach without one: it’s not really walkable from town, and it isn’t a stop most shared shuttles make on their own schedule. A taxi from La Fortuna is short and inexpensive, but you’ll want to arrange a pickup time rather than assume you can flag one down roadside on the way back — see getting around La Fortuna without a car for how other visitors handle this.

What “free” actually means here

Free means no admission fee, full stop. It does not mean maintained, monitored, or organised. There is no reception desk, no towel rental, no changing rooms, no restaurant, no bar service, and — this is the part people miss — no one responsible for the place at all. It’s public river frontage that happens to run warm, used by locals and increasingly by tourists, with whatever informal order the crowd on a given day creates.

On a good day, that looseness is the appeal: a handful of families sitting in the current, a couple of guides bringing small groups through as an add-on stop, nobody rushing you out after your ticketed hour is up. On a busy holiday weekend, expect a packed shoulder, cars parked awkwardly, and a current shared by more people than the spot really holds. There’s no one to complain to either way — you take the river as you find it.

Occasionally a local resident manages informal parking and asks for a small fee, a few hundred colones or a dollar or two, to keep an eye on cars along that stretch. It isn’t official, it isn’t guaranteed, and it isn’t the same as supervision of the river itself — treat it as parking goodwill, not security.

The safety picture, plainly

This is the part worth reading slowly, because it’s also the part most blog posts skip past on their way to the pretty photo.

No lifeguard. If someone gets into trouble in the current, the people who help are whoever else happens to be in the water. That’s true of a lot of river swimming worldwide, but it’s a real difference from every paid hot springs complex in this valley, all of which staff lifeguards as standard.

No lockers, no secured storage, no staff. Everything you bring to the riverbank sits in the open, unwatched, for as long as you’re in the water. There is nowhere on site to lock anything up.

Theft is a genuinely common complaint, not a rare exception. Visitors regularly report bags, phones, and cash going missing while they’re in the river, sometimes from spots that felt “watched” by the general crowd. It happens often enough that it belongs in this guide as a fact, not a caveat: do not bring anything you’d be upset to lose, and do not leave anything of value unattended on the bank.

None of this makes El Choyín a place to avoid. It makes it a place to visit deliberately — bring less, leave more locked away, and go in with the expectation that this is an unmanaged natural site, not a discounted resort. For the fuller list of ways first-time visitors trip themselves up around La Fortuna, see travel mistakes to avoid.

What to bring, and what to leave in the car

Bring	Leave in a locked car
Swimwear (worn, not packed)	Passport and other ID you don’t need on you
A towel you don’t mind getting a little muddy	Wallet — bring only the cash you’ll actually spend
Water shoes or sandals with a back strap	Phone, if you can manage without photos, or a cheap waterproof pouch you keep on your body
Small waterproof cash pouch, if you’re paying for parking	Jewellery, watches, sunglasses you’d miss
Sunscreen (apply before you arrive; there’s no shade to reapply under)	Camera gear, tablets, anything electronic beyond the minimum
A dry change of clothes for the ride back	Hotel key cards you don’t need

The car itself is only as secure as where you park it. A visible, locked vehicle on a public roadside is still a target of opportunity — if you’re travelling with a lot of valuables that day, it’s worth considering whether El Choyín is the stop to bring them all to, rather than assuming the trunk solves the problem.

Getting into the water

The riverbed shifts between sand, gravel, and rock, so footwear that stays on your feet matters more here than at a groomed resort pool — this is one of the few hot springs stops around La Fortuna where sandals with a heel strap genuinely beat flip-flops. Current strength depends on recent rain: after a heavy shower upstream, the flow picks up noticeably, and the river can run higher and faster than it did the day before. There’s no depth marker and no barrier between the warmer sections and the parts that have cooled toward ambient temperature, so expect the water to feel different a few metres in either direction rather than uniform like a pool.

Temperature closer to where the warm runoff enters can be genuinely hot; further downstream it tapers toward normal river temperature. Most visitors find a stretch that suits them and stay put rather than working the whole length of the accessible river. If you’re travelling with young children, this is worth weighing seriously against a staffed complex — see La Fortuna with kids for how families generally split their hot springs time between something like this and a resort with a supervised kids’ area.

Where El Choyín sits against the paid resorts

This isn’t the place to rebuild the full comparison — that lives on the hot springs comparison guide, and the shorter which hot springs to choose if you want a quick decision. But the shape of the trade-off is worth stating plainly:

	El Choyín	Paid complexes
Cost	Free (informal parking fee possible)	Roughly 40–115 USD per person
Supervision	None	Lifeguards, staff on site
Facilities	None — no lockers, no changing rooms, no food	Lockers, restaurants, bars, multiple pools
Setting	Natural riverbed, open to the road	Landscaped pools, often with volcano views
Crowd control	None — first come, first served	Managed capacity
Theft risk	Real and commonly reported	Low, with staffed premises

If the appeal of hot springs for you is the geothermal water itself and you’re comfortable managing your own risk and belongings, El Choyín delivers that for nothing. If part of what you’re paying for at a resort is the fact that someone else is responsible for the pool and your bag while you’re in it, that’s precisely what the free river doesn’t include — and no amount of careful packing changes that trade.

For travellers building a tight budget for the trip, El Choyín is one of the more meaningful savings available around La Fortuna, alongside the free viewpoints and self-guided trails covered in La Fortuna on a budget. Skipping one resort day in favour of the river can offset several other paid activities.

A paid option that keeps the natural feel

If the idea of river-style bathing appeals but the total absence of facilities doesn’t, there’s a middle option worth knowing about: a paid natural-spring property with jungle trails and pools built around the terrain rather than a resort deck.

a jungle-set natural springs property with marked trails and pools keeps more of the “real river” feeling than a big resort complex, while still giving you lockers, defined paths, and staff on site — a reasonable compromise if El Choyín’s lack of supervision is the sticking point rather than the price.

If you decide the free river isn’t for you

Plenty of visitors read all of the above and reasonably decide they’d rather pay for peace of mind, especially with kids, especially with cameras or phones they need for the rest of the trip, or especially on a day when the group just wants a straightforward afternoon without thinking about a locked car on a roadside. That’s a fair call, and La Fortuna has no shortage of staffed alternatives within a short drive.

Baldi’s tiered pools and volcano-facing decks are the most-booked resort option from town, with lifeguards and lockers as standard. Los Lagos’ springs and wildlife-park combination suits travellers who want to pair the water with an easy walk past crocodiles and toucans. For a smaller, less crowded resort feel, Paradise Hot Springs’ day pass is a quieter alternative to the bigger names.

Full detail on the two largest resorts, including which pools run hottest and where the crowds thin out, is in the Tabacón hot springs guide and the Baldi hot springs guide.

Combining El Choyín with the rest of your day

El Choyín works well as a short stop rather than a half-day plan — an hour or two in the water, then on to whatever else is nearby. Since it sits on the road out toward the volcano, it pairs naturally with a morning at La Fortuna waterfall or an afternoon around El Castillo, rather than standing as a destination on its own. It’s also an easy add for travellers already spending on spa and wellness treatments elsewhere in town and looking for a no-cost way to fill an extra hour with warm water rather than another paid stop.

Weather matters more here than at any resort: because there’s no shelter, no roof, and no indoor fallback, a sudden downpour — common in the green season covered in La Fortuna in green season — means standing in the open or packing up early. Resort pools give you somewhere dry to wait it out. El Choyín doesn’t.

The bottom line

El Choyín is exactly what it sounds like: a free, warm river with none of the infrastructure that comes with a ticket price. That makes it one of the best-value stops in the whole valley for travellers who pack light, leave valuables locked away, and go in expecting a natural site rather than a discount resort. It is not the place to bring your passport, your good camera, or an unattended bag — and it is not a fair swap for a staffed pool if what you actually want is someone else watching the water and your belongings while you relax in it. Know which trip you’re taking before you park the car.
