The islands are crisscrossed by small paths connecting one beach to another, but be prepared to sweat and swat off bugs if you tackle any of these. There is a good chance to see big monitor lizards and large spiders between Long Beach and Coral Bay, and if you are walking off the main trails, you are likely to spot some wild monkeys if you are lucky.
There is a wide trail (30 mins) between Watercolours Paradise and Arwana on Besar, you can see large termite trails, monitor lizards, big fruit bats and sometimes monkeys.
There is a paved walking trail from Coral Bay to Mira Beach (30 minutes) and on to Impiani beach (20 mins) and to the main fishing village on Kecil (20 mins). This is a great trail to see monitor lizards.
The Pulau Perhentian offer some great diving and excellent snorkeling. In addition to coral and fish, the Pulau Perhentian are home to sea turtles and many species of shark -- none of them dangerous unless provoked though.
Turtle Conservation Volunteering
The Perhentian Islands are home to a significant green turtle nesting population. The island was once home to hundreds of nesting Green and Hawksbill turtles but now the islands only receives 300 nestings per year partly due to frequent oil spills from oil production platforms and oil tankers owned by Petronas located not too far away.
Popular snorkeling spots on Besar include Teluk Pauh (to the left of the beach in front of the PI Resort), Shark Point and Tanjung Basi. The best place to see sharks (black tip) is in front of an extremely small "beach", only accessible by boat, between Shark Point and the Teluk Dalam large beach, or the rocks off the Coral View and PI Resort.
