Each island individually can simply be navigated as an easy day trip, and it is probable to do both islands in a day.Small is 8.5 miles in circumference and takes 3 hours of constant easy paddling. There is a lot of opportunities to stop and explore some of the more isolated beaches and snorkel.Big, the larger of the two islands, is 10 miles in circumference.
The islands are crisscrossed by small trail connecting one beach to another, but be prepared to sweat and swat off bugs if you tackle any of these. There is a nice chance to see large monitor lizards and massive spiders between Long Beach and Coral Bay (Kecil), and if you are walking off the main trails, you are likely to see some wild monkeys if you are lucky.There is a wide trail (30 mins) between Watercolours Paradise and Arwana on Besar, you can find 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 primary fishing village on Kecil (20 mins). This is a supreme trail to see monitor lizards.
5. Turtle Conservation Volunteering
The Perhentian Islands is a place for a notable green turtle nesting population. The island was once home to hundreds of nesting Green and Hawksbill turtles but now the islands only receive 300 nestings per year partly due to recurrent oil spills from oil production platforms and oil tankers owned by Petronas located not too far away.
