One highlight of the Cham Islands are the various dive sites. For a dive trip contact one of the diving centres. I used Cham Divers, based in the Ancient Town of Hoi AN. They offer several packages for divers and non divers, including Padi courses, try dives, fun dives, snorkelling – either as a day package or a two day package that include overnight stay on Cham island (sleeping in a tent on the beach). Prices starts from $72
Their boats are spacious, with a large sun deck to relax, space on the ground deck to get some sun protection, and a good platform to get in and out of the water. Water, tea, cakes and bananas were provided free of charge throughout the day. They also had a few books on board to see what fish were spotted during the dive. Very handy for people new to diving. Lunch is not served on board, but on a beach on Cham Island, where the afternoon is spend to relax.
