Tour was fantastic. Pictures prices are ludicrous, No reason tourists couldn’t take in their cell phone to take their own photos. But overall don’t miss the amazing scenery!

Adam – Australia

Amazing morning. Transportation was on time, hiking equipment was all supplied and in good condition, lockers supplied, towels supplied. Tour guide was friendly, approachable and informative. The scenery was amazing and the trek itself was fairly easy and slow paced which was great. We were all in small groups so you can appreciate the experience even more. Lunch was an awesome buffet at the end. Overall a great way to spend a morning and would highly recommend.

Full description

Be immersed in an ancient world of stalactites and stalagmites. Roam the labyrinths of dramatic rock formations and tranquil waters. The Rio Secreto (Secret River) is a hidden underground network of rivers and caves.

An air-conditioned mini-van collects you from your hotel and takes you to Rio Secreto. Here you will meet your expertly trained guide and receive a wetsuit, wet shoes, a lamp and a helmet to get you ready for your adventure.

From here, enter the caves, where for 600 meters you will be free to walk, swim and enjoy the enchanting beauty of your surroundings with the supervision of your guide. Furthermore, with a maximum of 12 people per tour, you can be ensured a quiet tour experience free from outside distractions. The tours in Rio Secreto are organized so that no two tours happening at the same time will meet underground.

After approximately 1.5 hours you will be taken back to ground level and treated to a light lunch of delicious local food. Choose the green salsa if your taste buds like it hot! This is a chance for you to relax in the serene jungle habitat and reflect upon your experience in the caves. After this, you may wash and change before being transported back to your hotel.
