There is enough for the children to see, but not exactly alot. This is a visit of about 90 minutes.
Just like just about everything else in Bintan, it is also somewhat overpriced. First there is the entrance fee, then it costs IDR500,000 for a buggy which can take up to 5 pax (we needed two buggies because we had more than 5 pax), and animal feed (vegetables, carrots, and a piece of chicken for the crocodile) costs IDR250,000 per bag (even in Singapore, I should be able to get all of those at the supermarket for 30% of that cost).
There is some effort to provide a decent-looking enclosure for some of the animals, but for the others, I have to agree with the other reviewers that they are kept in bare-looking cages which hardly meet the animals' needs.
