Billy Barquedier National Park is located on the Hummingbird Highway at mile 16 1/2 in Steadfast Village. I have never visited the park myself, but there are several references to it online now. The park is co-managed by the Steadfast Tourism and Conservation Association.

The main attraction seems to be the falls located inside the park. The park is approximately 1639 acres in size and is mostly Lowland broad-leaved moist forest.
