My friends and I went out with Captain Mark’s Phuket Sails Kho Phanak Sail Caves and Hongs Tour to explore the caves and hongs (hidden lagoons) in Phang Nga Bay, home of the beautiful limestone Karst scenery. The caves were cool and the mangrove lagoon was awesome and we found an isolated beach where we swam and had a picnic lunch.  Then we put sails up for the trip back into Ao Por.
