Carlos and Mario were very pleasant and worked hard to find us as many monkeys and sloths as possible to see. Picked us up at the time they said and dropped us off. Provided: two restroom breaks, water, snacks, comfortable covered boat ride with music (an additional $20 cash per person), short hike in rain forest on gravel road (some bugs so pants and bug spray if you really dislike bugs, but wasn’t too bad). Tour provides a wide variety of information. Wonderful experience for our family.
