It's worth the hike. - Carlos was a great tour guide who could find animals like no others. He even bought local pineapples to treat us. The rain can come in unexpectedly - Prepare your ponchos and wear water proof hiking shoes for sure!

Blue waters - Absolutely amazing day with guides Andres and Cristian. It is a walking tour like difficulty 7/10. The use of a walkking stick can be of good use. The energy and know-how of the guides will surelly make your day. At the end the swim at the cold water of river with fruit snaks ends perfectly the Journey.

Unreal Experience! - Highly recommend this tour! It was my favorite experience during my time in La Fortuna. The entire day was well organized and never felt rushed. Annie was an excellent and informative guide, and the small group made it even more special. Definitely bring water shoes if you plan to swim in the blue lagoon afterward!

Rio Celeste tour did not disappoint - Lots of impromptu stops to see wildlife on the way there made the trip amazing. Great coffee stop also! The hike was challenging and fun. Beautiful blue falls! Santiago was great and spotted snakes and sloths along the way. Fun day with a small enough group that everyone got to be friendly. Pura Vida

Great guide, photos, and saw lots of animals - Santiago was a great guide. It was a long hike but so worth it. Probably the first and affordable tour where you feel like you’re going all in for the experience. All pictures and videos came out great too!

Great guide with lots of knowledge! - A good experience that is worth doing! Our guide, Annie, had eagle eyes for spotting animals on the drive to the park and on the walk within it, and great knowledge to answer all our questions. The park itself is wonderful - super interesting learning about the science behind what makes the water it's famous blue, and getting lots of photos. Not 5*s as we got collected before 8am but then didn't enter the park until 11am despite it being a 90 min drive - felt somewhat inefficient and we had to wait around a bit at various stops. That late entry also contributed to only getting lunch by 3pm and back by 6pm, so a long day.

A kind of safari - We went with Annie (gide). It was nice experience and easy tour. We’re hikers (me and my husband) , but because of our age we have to adjust our hiking activities. Of course there were very many people/visitors on the trail. But we saw also some animals (snakes and mummels
