Probably the best dive site we encountered on a week long liveaboard. You enter an enclosed corridor filled with sweepers and soft corals and the force of nature grabs you and pulls you through, spitting you out the other end! Once through there is a super reef on the other side where I have never before seen so many morays - free swimming, hanging in sea fans. Pretty good dive by anyones standards!
