it's really important to support a legit operation like this vs the others who are not in the business of protecting the animals.
it was great to see REAL conservation in the Philippines. we were lucky enough to meet the founder (carlito) too while we were there! the staff was great and showed us exactly where the tarsiers were napping. we only saw a couple of tarsiers - they were hiding due to the rain, but carlito mentioned that within the sanctuary, there were 5 pregnant tarsier mammas in the mix. the forest surrounding the sanctuary is also part of the center (donated by the government) for the protection of the animals.
Wear appropriate shoes as it's slippery when wet....you are in the forest!
