Free Hot Springs in La Fortuna: The El Choyín River

A Real River, Not a Built Pool

El Choyín is a natural river. The water is warmed by runoff from the same geothermal source that feeds Tabacón just upstream, so it is genuinely thermal water flowing over a wild riverbed. There are no constructed pools, no filtration and no staff of any kind. Locals call it mini-Tabacón or Tabaconcito for that reason.

This matters when comparing it with La Fortuna's paid options. Most venues around Arenal pump geothermally heated water into constructed pools, and some, like Baldi or Kalambu, add waterslides and play more like a water park. Only a few places have water that runs as a river: Tabacón, Hot Springs Pura Vida and this free stretch. All of the area's springs, free or paid, draw on heat from the Arenal volcano system.

The river is free because it is simply unregulated public riverbank. No municipality, no tourism board and no national park administration manages or maintains it. Nobody checks the water quality and nobody is on record endorsing access. That is the trade for the Free price.

Who Should Pick a Different Spring

The honest answer first: the free river is not for everyone. There is no lifeguard at any hour, no staff, no locker, no bathroom and no cell signal at the bank. The rocks are described as incredibly slippery when wet and the current near the main channel can run rough.

If you are traveling with small children, if anyone in your group is a non-swimmer, or if you want a changing room and a place to lock your phone, a cheap ticketed venue will serve you better. Hot Springs Pura Vida river and thermal pool access covers a natural thermal river plus a pool for $29, with the same kind of rocky riverbed but an operator on site. If you just want constructed pools at a low price, the guide to cheap hot springs in La Fortuna compares the small family venues.

Finding the Path Down

Drive Route 142 northwest out of La Fortuna toward Lake Arenal. The access point sits on the same side of the road as, and immediately after, the Tabacón resort entrance. The drive from town takes roughly 16 minutes, about the same as Tabacón itself.

There is no signposted entrance. A small gate or broken-fence gap on the north side of the road marks the informal path. Park on the shoulder, then walk across or alongside the road bridge over the river, a span of roughly 100 feet. From the bridge, looking back toward La Fortuna, the main path down is on the right. Walking under the bridge to the left reaches one set of pools. Climbing over rocks to the immediate right reaches another.

The name varies between El Choyín, El Chollín, Río Chollín and Río Choyín. Third-party guides treat all four spellings as the same location, so a driver who knows any of them will get you there. Ask for the Tabacón Hot Springs entrance rather than Tabacón Resort, since taxi drivers may otherwise default to the resort gate.

Why the Morning Wins

Guides consistently recommend arriving between 6am and 8am. At that hour the river is quiet, the rocks are dry from overnight, curbside spots on the shoulder are easiest to find, and the informal parking attendants described below are typically not yet present. Visits after 8am risk both crowding and the parking fee solicitation. After dark is strongly discouraged: the site has no lighting, no staff and no security at night. Daylight only.

Air temperatures in the area average 75°F (22°C) annually, with daytime highs between 73 and 88°F (23-31°C), so an early start is comfortable rather than cold. In the rainy season, which runs May through November with the heaviest rain June to October, an early slot also lowers your flash-flood risk, since heavy afternoon rain is what stirs the river up.

The Parking Attendant Issue

There is no official parking lot. What you get instead are informal attendants in high-visibility vests who position themselves at the roadside and offer to watch your car, demanding payment reported at 3,000 to 5,000 CRC, roughly $5 to $10. This is not a regulated or ticketed service. One visitor reported being told bad things would happen to the car if they did not pay.

The fixes: arrive before 8am when these attendants are typically absent, take nothing of value with you, and leave nothing visible in the car. if you pay an unofficial guard is entirely your own decision and risk. No posted fee exists because the spot is not an authorized lot.

Buses and Taxis

Without a car, a taxi from La Fortuna costs roughly $20 one-way at minimum. Tell the driver the destination is the Tabacón Hot Springs entrance, not Tabacón Resort. A local bus toward Tilarán from the La Fortuna terminal can drop passengers near the site if you ask the driver.

One detail catches people out: there is no cell signal at the river itself, so you cannot order a return taxi from the bank. Arrange a return pickup, or a fixed collection time, before you walk down. A shuttle service called EasyHop used to serve the stop, but it is now discontinued, so the bus, a taxi or a rental are the remaining options.

Slippery Rocks and Current

The riverbed rocks used to reach the warm pools are described as incredibly slippery when wet, which is most of the time. Wear water shoes and move slowly. The current in the main channel can be rough, so stay in the calmer pooled sections rather than the fastest-moving water.

The most serious risk is a flash flood or surge during the rainy season. If the water turns brown or murky, leave the river immediately. Heavy rain upstream can raise the level with little warning, and with no staff on site there is nobody to sound an alarm for you.

Theft, Isolation and Darkness

Theft from unattended bags is a recurring complaint at El Choyín. Visitors commonly leave phones, keys and bags on the rocks while they soak, and a posted sign warns against it. The fix is simple: bring only what fits in a waterproof pouch worn on your body, and never leave valuables in view in the car.

There are no lifeguards, no staff, no police presence and no public phone on site, so visit in daylight and with company. After dark the site has no lighting and no security, which is why night visits are strongly discouraged even though the riverbank is technically open at all hours. There are also no bathrooms or changing facilities, so arrive already in your swimsuit.

The Paid Operator Now at the Same Spot

Part of the story changed recently. A small commercial operator branded Choyín Río Termal opened right at this same location, charging a paid day pass that includes lockers and food service. Some of what used to be entirely free riverbank access now sits behind a fee, though free sections remain along the bank.

If you want the river with lockers and food on site, the ticketed access at the same stretch is now an option, and it is the meeting point for the $29 Hot Springs Pura Vida river and thermal pool pass.

The Short List

Water shoes are the single most important item because of the slippery rocks. A waterproof pouch for your phone and keys solves the theft problem, since it stays on your body in the water. Wear your swimsuit under your clothes, because there is nowhere to change and nowhere dry to leave a bag. Bring a towel, drinking water and any food you want, since there is no vendor or staff presence at all and no restriction on outside food.

Leave behind jewelry, wallets, passports and anything electronic you do not need. If you drive, hide everything in the trunk before you arrive, not while standing at the shoulder. And sort out your return transport before you walk down, because the lack of cell signal at the river means no ride can be summoned once you are on the bank.

River Access Compared

Three of these options keep you in a natural thermal river, the same product as El Choyín, while the last two are constructed pool venues at the low end of the paid market. Prices below are the ticketed tour prices this site tracks, and each links to its own detail page. Use the table to match the price against what you get: transport, a guided hike, lockers or simply a staffed gate.

The cheapest of all is Los Laureles, a small locally run venue with no bookable tour on this site, reported at $12 for the entire day, where you may bring your own food and where locals soak too. If you want the free river experience with a guide and a volcano hike attached, the Arenal Volcano Hike + Hot Springs River tour at $54 includes round-trip transport from the La Fortuna zone and about 40 minutes in the Río Choyin after the hike, with the park and springs entrance bundled in. For a staffed river with a pool and rainforest around it, the Hot Springs Pura Vida river and pool pass costs $29 and needs no transport since it runs from the Choyín Río Termal meeting point.

What a Paid Pass Buys That the River Cannot

The jump from Free to $29 or $54 buys staff, lockers, bathrooms and a way to call for help. At the guided $54 tour it also buys transport, which removes the parking-attendant problem entirely, and a guided volcano hike on top. Even the full resort end of the market is worth understanding for contrast: the Tabacón day pass runs $180 for the resort's spring-fed river and pools, which shows how much of the same thermal water you are getting for free at El Choyín, minus the landscaping, the lockers and the lifeguards.
