Rio Celeste Full-Day Hike: Blue Waterfall & Tenorio Volcano

Highlights

Inclusions

Itinerary

1. You'll then engage in a 4-hour hike that is a bit tough for some but the end result is definitely worth it. After your 4-hour hike you'll get to the Rio Celeste (Blue River). The blue color you'll see is the result of a chemical reaction between two merging rivers containing different volcanic minerals. It's a very rare phenomenon which creates a fairy-tale-like beauty. You'll get to see a waterfall, a lookout point that's great for taking pictures and you'll also get to see the place where the river changes colors.

• 5Day Hike

  We had a great time, and the tour gave us an opportunity to escape the crowds and get close up to some of Costa Rica’s wildlife. Our guide, Santiago, was informative and fun, pointing out the wildlife and things about the culture along the way.

• 5What a great day!

  We had the best time today on our tour with Santiago. There was a little mix up in the beginning with bus assignments, but the company made it right immediately and Santiago ended up giving our family our own tour. The views of the waterfall were lovely and Santiago made it a point to include all of our kids in the fun animal sightseeing on the way (both on the side of the road and in the park). We split up for the more challenging half of the hike. The littles and their older sister (ages 4, 6, and 14) enjoyed fresh fruit and a little shopping with dad across the street while Santiago brought my older son (age 11) and I on the more challenging loop after the waterfall. Lunch was fantastic with fresh juices followed by a very tasty Casado (or hamburger/chicken fingers for the kids). I would absolutely recommend this tour to anyone visiting the La Fortuna area!

• 4Forest Hike

  This hike was overall a nice scenery and wildlife experience. We took a trail through a national park in the middle of the woods, and we passed much wildlife like snakes and spiders. We also got to see the huge waterfall and some cool sulfur deposits, and our tour guide was friendly and knew a lot about the animals. Most of all it was some much needed exercise! The only thing was that the hike is tiring and gets repetitive, and it rained the whole time, so we couldn’t really see the blue lagoon at the end. Of course you can’t really control this, but be aware that it’s for the physically fit and strong minded.

• 5A beautiful and exciting...

  A beautiful and exciting way to spend the day! We loved our day with Santiago, Ani and Roberto. They were amazing wildlife spotters and educators, extremely clear communicators, and excellent planners. What a special day!!! We saw so many creatures that we would never have spotted on our own, and we learned so much. Mahalo nui loa to our amazing guides and driver. Pura vida!!!

• 5Great hike

  Santiago was an amazing guide! Every informative, went the extra mile. Our group was about 8 people which was nice, as my other tours felt a bit crowded. Unfortunately the water was not blue when we went due to the heavy rain the day before. but Santiago did his best to make the experience worth it, and it was! We saw many different snakes, spiders, and a family of sloths close enough to see without binoculars! The lunch was very tasty.
