It is only allowed to enter the parc with a guide which is absolutely okay.
The guide was a good guy and he loved the nature and pointed out the details such as frogs, snakes, birds, geckos and nice plants.
So 2 hours is enough and well worth to invest the time. Also the boat tour in the bay was very nice. We loved the sourroundings of this site in general in Cuba. Wonderful spot.
