Many places have good birding is good along the roads.
In El Remate look along the road Biotopo Cerro Cahui Park. There are free bicycles at the hotel. A two hour boat trip in the evening takes you across the lake and up some of the small rivers of Xpop or Ixlu for roosing sites and other birding areas. The park is 2 kms. It has more than 10 Kms.
