This destination should be included in every "classic" city tour in Puerto Princesa. The place is first composed of a butterfly garden, which you will discover first when entering. There are a lot of butterflies flying around, so you'd better not be afraid of these beautiful insects!
Around the garden, there are also a few enclosures hosting local birds, turtles, (small) crocodiles, geckos, bear cats... all animals living in or even endemic to Palawan. There is also a nice collection of insects including beetles, scorpio and stick insects.
The second part of this destination is dedicated to the sharing of cultural aspects of the Palaw'an people. This is the "tribal village" part of the place, where people originating from a local tribe demonstrate some of their craft, music and hunting technics. You will also get a chance to hold one of their "pets" : a python snake!
Finally, there is a little shop by the exit of the premises, where you can find souvenir and local products. The visit of the place will take around 1 hour including both the eco-garden and the tribal village. This is definitely a place to visit in Puerto Princesa, and one of most interesting as it's offering a mix of nature, education and local culture sharing.
