There is a visitor center as you enter the village right after the causeway. Be sure to stop in to get information on the local goings on.
The Crooked Tree Wildlife Sanctuary is open daily and is USD $8. Where "it" is is a bit hard to define but the village proper sits within the Sanctuary.
Crooked Tree's main feature is birdwatching. The village sits off an inland lagoon and there are hundreds of species of exotic birds to be seen with almost no effort. Local guides can take you to the best spots to see the highest variety. The highlight is the Jabiru stork which is the largest flying bird in the Americas.
You can also do some boating about the lagoon. Rental prices can be high but the views are generally excellent and afford you the opportunity to see even more of the bird species. Again, local guides are available.
Chau Hiix is a Myan site that is being excavated. It is about a 3 hour canoe to trip each way from the village. When they are about, usually the dry season, on-site archealogists can give you a tour.
