No secrets here....Take cab to flash of beauty. Talk to restaurant there about which way to start. Typically East to West. If so walk down beach to damaged hut swim out and drift snorkel back.

You can walk to Big Bamboo on beach if you want after you have chicken Roti at restaurant (Monica I believe is her name)

I highly recommend to you and insist my crew use noodles when they snorkel for both flotation and identification in water...especially here

Big Bamboo snorkeling is usually also east to west following the semi circle

Some TTOLer put up map of it if you search
