I've done 5 dives at Sund Rock, all of them via the $15 private access available through the local dive shop. Access can't be any easier if you pay the fee, but I guess it's a bit of a swim if you do the economy version. The aquatic life is extremely abundant, likely due to the fact that it's a marine reserve so remember, no hunting or collecting. I prefer the south wall, but the north is an excellent "deep" dive. I've been down to about 80 ft there. Visibility tends to be rather good, but watch out for overwhelming crowds on the weekends. This is my favorite dive in the NW!
