Hi everyone. My sister and I are staying in a bungalow on the Surin Islands from the 16th to 20th Feb. We were wondering if it's possible to hire or join a boat to collect us from the Surin Is. for a day trip to Richelieu Rock. We want to go snorkelling / free diving at some shallower sites on he rock. All the boats to Richelieu I've seen leave from the mainland, so I don't know if this is possible. Any information would be great. Thanks!
