Diving in Southeast Asia — done honestly.

We are an independent guide. We do not sell courses, run a dive shop, or arrange trips. We write what we would tell a friend planning their first or fiftieth trip to the region.

Why an independent guide

Dive schools and tour operators have a financial incentive to sell you their courses and trips. Booking platforms have an incentive to rank by commission. We have neither. We write about what works, what doesn't, what we'd actually do.
