I love Samar! They have lots of Eco Tourism Parks like Minasangay Island and Divinubo Island Eco Tour Park.
Divinubo Island is located near Borongan, Eastern Samar and the jump-off point for the public boats are at Lalawigan. The Eco Tour Park is managed by the Community-Based Resource Management (CBRM) Program and was a way for the baranggay to sustain the natural beauty and biodiversity of the place at the same time earn a little income.
Is the island worth going? YES! Better if you spend the night there with your hammock. If you get there around 4PM you may be able to see the sunset with the view of mainland Samar.
