Plenty of monekys scampering around in the trees behind the mermaid cafe. The people there leave on the water for them to drink which I thought was nice. There are some monitor lizards around though so be careful!
Looks possible to rent one of those land rovers to ride around in but Im not sure.
Sadly the hiking trail to monkey beach is closed and you can only take a boat from turtle beach/national park for 100MYR. The campsite is also under renovation from Oct 2023 until further notice.
