Hi turtle beach is at Dalayan, we did a boat trip last year, its a long day, left about 9.30am returned about 8pm but well worth the trip, we were lucky enough to see a very large turtle, local fisherman lured one up with a crab, amazing sight

, they
transfer you to a smaller boat to go along the river to mud baths, baths are stinky but good fun, sea gets a bit choppy on return but we thoroughly enjoyed the whole day.
