the blue holes in palau are really nice for fun freediving.
carefull: its not the virgin blue hole if i remember right.
called just blue holes.
its actually 3 or 4 blue holes if i remember right. close to each other and connected between each other and also connected to the sea.
not too deep. we experienced medium/big waves on the surface.
maybe i find the video we took.

have been there in february/march (shark mating season) and it was awesome.
imagine exiting a blue whole to the sea and having sharks on the outside.

bye,

Having dived the Blue Hole in Belize, I agree it is largely marketing hype, thought it is a geologic marvel. Pictures from the air (and the one posted of the skydivers is fantastic) are wonderful. But the dive itself is a deep (110feet) bounce to the "cavern zone," with bottom time of about nine minutes. The stalagtites and mites are impressive, but you can see much better formations in the Cenotes in the Mexican Riviera below Cancun. (Choc Mol is one of the nicer ones). It is also a bit unsupervised as a tourist attraction, so there are often quite unprepared, relatively new open-water divers doing the dive. I got narced a bit... and I wonder about someone with little experience dropping into the blue to 110... with no bottom for perspective. The coolest part for me was coming up to a sand patch at 50 feet and having lots of sharks and huge grouper swim overhead. It is also long (normally 2-3 hour) boat trip from land, and when I did it we fought six-foot swells and winds out, which made the trip more a very bouncy four hours. Cavern diving in Mexico is great... I'll stick with that and pretty fish on the reefs.
