In all my traveling, I've never seen a place quite like this. This is more than just the typical zoo or aquarium experience. It's a more laid-back and real way to experience animals just being animals. The exhibits are well maintained, and if you didn't know any better, you'd think they were the real thing.
We loved watching the sloths. In every zoo ever, they just sleep all day, but these sloths climbed over our heads, "chased" each other (they are really slow so it can't really be a chase, I don't think?), and were just really cute -all within an arms reach of us.
The place can get crowded very fast and isn't very big, so I would recommend going in off-season, and on a weekday.
