Monsoon season should have been clearing up by mid Feb, but a late start has meant a late finish and it was pretty wet when i was there. The water was still pretty clear and when the sun did come out it’s easy to see how this place can be a tropical paradise.
I Stayed at Tekek and Salang beaches and both were near enough void of any other tourists except a few couples skipping work in KL for some R&R and of course some hippy backpackers after cheap booze and ciggs. (Being one of the lucky islands in Malaysia that is duty-free, Tioman booze is less than half mainland prices so fill your boots like the backpackers did).
With the exception of a 2k road through the main town of Tekek there are no paved roads, so the scooter was left by the pier in Mersing. The toothless old guy i parked it next to assured me it was safe to leave for a few days, and happily it was still there on my return. Surprisingly enough, so was the old toothless guy.
