Dove at Cai last week on my first diving holiday. Although with 2 experienced divers, I was very worried about the reported current. However we had no difficulties making it in & out the channel at all, but this may be related to us being used to some current in the Oosterschelde (NL) anyway. Beautiful reef, but no eagle ray spottings due to rather low visibility on the sand... Still, a very nice dive! Resist the urge to drive straight to the surf club at Lac Bay for a beer after the dive, but mingle with the locals at the local bar - entertainment guaranteed!
