We took the Monkey Mangrove tour and loved it. Our driver was incredibly nice and accommodating. The tour was terrific. We saw a ton of different kinds of animals and the guide was easy to understand and described everything we saw. Best of all we saw monkeys close up - even on our heads! My kids really enjoyed this. We also went to the beach at Manuel Antonio on the same day which was also nice. I would highly recommend this company, they are friendly, reliable, less expensive than the Marriott resort, where we stayed, and offer great tours.
