Rio Celeste Hike, Sloth Sanctuary & Llanos de Cortés Waterfall

This is the longest itinerary on the site, and the only one that packs three distinct stops into a single day from the Guanacaste coast. The day starts with a swim and photos at Llanos de Cortés waterfall, a wide curtain of water with a sandy bank that sits outside the national park. From there the shared minivan pushes inland to Tenorio Volcano National Park for the Rio Celeste hike, roughly three to four hours on the trail past the waterfall lookout, the hot springs, the mud pots, Blue Lagoon and Los Teñideros, the springs where two mineral streams meet and the river turns opaque sky blue.

The third stop is the Jungle Life Sloth Sanctuary, where sloths are observed in a reserve setting and never handled. A Costa Rican lunch and national park fees are included in the price. The listing carries 1,178 reviews at a 4.62 rating, which makes it the most-reviewed Rio Celeste tour in this comparison, though not the highest rated.

The trade-off for that volume of reviews is the rating and the length. At 4.62 it sits below every other guided day here, and reviewers who marked it lower most often pointed at the length of the transport. The drive from Liberia and the northern Guanacaste resorts takes about two to two and a half hours each way, and the day absorbs that twice.

If the three-stop format appeals but the Guanacaste drive does not, the closest alternative is the Rio Celeste Waterfall & Slothland Excursion, which pairs the park hike with a sloth reserve at Bijagua and runs 11 hours with transport arranged separately.

The tour includes the national park entry fee, so you do not buy a ticket or deal with SINAC yourself. Entry slots to Tenorio Volcano National Park are capped daily, the entry window runs from 8 a.m. to 2 p.m. and independent visitors buy timed tickets in advance online. Going with a guided day removes that booking step.

The official entry price for foreign adults is $12 plus 13% tax, about $13.56, and children aged 2 to 12 pay $5 plus tax, all of which sits inside the tour price.

The swim rule is the one that catches people out. Swimming is prohibited inside the national park, including at the Rio Celester waterfall pool, and the rule applies to every visitor with or without a guide. The swim on this tour happens at Llanos de Cortés waterfall, which lies outside the protected section, and that is where you should pack your bathing suit.

The Rio Celeste Nature Hike & Swimming at the Blue River takes a similar approach from La Fortuna, with its swim stop at a river spot outside the protected section.

Weather changes the day in two ways. Heavy rain turns the river green-brown within hours as suspended sediment overwhelms the light scattering, and the blue returns as the sediment settles, so a rainy week can mean a brown river even on a perfect itinerary. Llanos de Cortés can also run brown after rain.

The park trail closes in extreme weather, and tours run rain or shine unless the park itself closes for floods or landslides. The timing of the blue is covered in more depth in When to Visit Rio Celeste: Months, Color and Crowds.

The $135 base price buys the guided Rio Celeste hike, the Llanos de Cortés stop, the sloth sanctuary visit, a Costa Rican lunch and the national park fees. Free cancellation applies up to 24 hours before the scheduled departure. There is no reserve-now-pay-later option on this listing.

The transport catch

Shared round-trip transport is not included in the base price. It adds about $120 per person on top of the $135, which pushes the realistic per-person total to around $255, and some far-flung resorts add a further pickup fee. There is no pickup at all from Andaz, Planet Hollywood, Four Seasons, Waldorf Astoria, Catalinas or JW Marriott and Pinilla without paying a fee.

Gratuities are excluded. That means the headline figure understates the true cost more than any other listing in this comparison, and it is the main reason the entry ticket route or a La Fortuna departure can work out far cheaper.

Ways to run the day

The listing offers three formats. The shared minivan from the Guanacaste resorts is the standard option. Self-drive travelers meet the group at Llanos de Cortés at 9:00 am or at the park at 11:30 am, which removes the transport surcharge entirely.

A private van option exists for groups who want the vehicle to themselves. If you drive yourself, the route from the northern resorts runs down Route 1, then Route 6 toward Upala to Bijagua, then a right onto the paved entrance road. For more on the roads, see How to Get to Rio Celeste: Routes, Roads and Times.

The listing does not publish a minute-by-minute schedule beyond the pickup window and the self-drive meeting times, so treat the sequence below as the shape of the day rather than a timetable. What is fixed is the order: waterfall first, park second, sloths last.

Resort pickups start about 6:20 to 6:45 am depending on your hotel, and the drive from Liberia and the northern coast takes about two to two and a half hours each way.

This is the longest day here and, once the transport surcharge is counted, the most expensive. It is also the most reviewed, with 1,178 reviews, though its 4.62 rating trails every other guided option. If you want sloths at a higher rating and a lower price, the Slothland excursion is the direct rival.

If you are staying in La Fortuna rather than Guanacaste, the La Fortuna listings cut the day by four hours. Figures current for Q3 2026.

Difficulty and what to bring

The difficulty is rated moderate: three stops in one day with a humid rainforest trail in the middle. The first 20 to 30 minutes of park trail are flat and paved, then a long staircase with a railing drops to the waterfall lookout, and the trails were rebuilt so they no longer turn to mud in rain. Bring a bathing suit and towel for Llanos de Cortés, closed walking shoes, a rain jacket and cash for gratuities.

Rules and restrictions

• Swimming inside the national park is prohibited, including at the Rio Celeste waterfall pool
• Drones are not allowed
• Pets are not allowed
• Free cancellation up to 24 hours before the scheduled departure, no reserve-now-pay-later option

Pickup limits

Check the pickup list before you book. Andaz, Planet Hollywood, Four Seasons, Waldorf Astoria, Catalinas and JW Marriott and Pinilla are not served without a fee, and some far resorts add their own pickup charge. Self-drive travelers avoid all of it and meet at Llanos de Cortés at 9:00 am or the park at 11:30 am.

Wildlife expectations

The park and its surroundings hold sloths, tapirs, toucans, howler monkeys and poison-dart frogs. Sightings are common but never guaranteed, at the sanctuary or on the trail. At the sanctuary the animals are observed, never handled.

Book this if you are staying at a Guanacaste resort, you have one free day and you want the fullest possible Rio Celeste experience without renting a car. It front-loads the logistics: pickup at your hotel, a guide who explains the mineral chemistry at Los Teñideros, lunch handled, park fees paid. Swimmers get the most out of it, since Llanos de Cortés is the best swimming stop of any listing here.

Skip it if the true cost bothers you. Once the $120 transport surcharge lands, you are paying more than double the La Fortuna listings for a longer day in a vehicle. Travelers from La Fortuna should look at the Rio Celeste Full-Day Tour from La Fortuna instead, and budget travelers who are happy to self-guide can do the whole thing for a fraction of the price with the Rio Celeste Waterfall & Tenorio National Park Entrance Ticket.
