Completely worthwhile, educational and fun. A highlight of our trip to the Arenal area. We took the tour and volunteered for the morning session. Carlos, our guide, was a delight, Andy we learned a TON about: spider monkeys, peccaries, macaws, parrots, parakeets, coatimundis, kinkajous, capuchin monkeys, boas, etc. We had the wonderful chance to interact with most of the animals, with the knowledge that when they are able, Proyecto Asis releases their guests into nature.
The group size was small, which was also very nice (the people were also congenial).
Our volunteer duty was meal prep and feeding, which was pretty darn cool.
The cost for two was about $100 US, but when you see the care and attention to the animals' welfare, you realize it's money well spent. This should be on your must-do list if you love animals.
