Yeah, that's me. The lions seem use to being around people.
Another fascinating experiences was coming across leaf cutter ants in the rainforest. For some reason i find them fascinating to watch and observe. You'll see plenty of colonies in the Costa Rican rainforest so watch where you stand.
Baboons are numerous in the jungle as well. They are not as mischievous as white faced monkeys but they can be mischievous as well. I encountered a bunch while hiking up. Here's one holding a water bottle.
