Transport, water and parking are included, lunch is not, and it asks for a high level of fitness. 4.98 from 1776 reviews at €114 per person. In our comparison: #1 of 70 in Day Trips, by rating weighted by review volume (table below). ## Overview A fun and adventurous day hiking, river trekking and floating through caves and beautiful greenish blue pools (optional cliff jumping too). Swim through breathtaking limestone canyons, stunning caves and unique rock formations carved by the passing of the river, surrounded by beautiful, lush tropical forest scenery and a waterfall. An early start (to avoid the crowds) and smaller groups guided by an experienced and Certified Tour Guide provides a safer, more intimate and immersing experience with insightful information of the island. Later enjoy some authentic delicious puertorrican food at a local restaurant. End your day hiking a short trail to a small hidden natural spring with pristine water, while learning about the local plants and trees. An unforgettable experience for adventurers seeking less touristic favorite local spots. Tour requires GOOD PHYSICAL FITNESS, balance, flexibility, river trekking skills and BASIC SWIMMING SKILLS.
