We booked through Klook and ended up with this terrible tour company. The boat had 23+ people on it, with not enough room for everyone to sit, told the tour guide that this was very dangerous and that we were not happy at all. First stop main island was a total waste of time, not much to see here at all. Then onto next island climbing in and out of the boat from the bow, no ladder provided, so is very difficult if you are not young and fit, driver does not help at all. Told we could have 15 minute swim, then back on boat to a cove where you are given ancient snorkeling gear, no flippers and to climb down the dangerous sharp ladder to water, even harder to get back in the boat. Back to smaller island for a lunch that I would not rave about and then told to sit on beach and have a sleep for 1 and 3/4 hours......
on return trip there was not enough room for everyone to sit under cover so my husband and I volunteered to sit in open in the bow, best part of our day.
Would not recommend this tour company. Very dangerous, money grabbing, definitely not worth it.
