Of the many scuba diving sites offered by Grand Cayman Island I believe that Black Rock Wall must be my favorite. If you ever get the opportunity to dive this amazing site don't hesitate. Looking back through my dive log I find that over the years I dove Black Rock four times - three night dives, and a day dive. Those night dives were the most spectacular, but then I'm rather partial to night dives. I saw my first octopus during a night dive, and yes that was a dive at Black Rock. I got a couple of decent pictures of two octopuses that night.
Black Rock is on the north side of Grand Cayman just about halfway between the center line of the island, and the east end. The dive site starts at a depth of 25-feet, and then gradually drops to around 60-feet where you plunge over the top of the Cayman wall. My day dive at Black Rock was to 96-feet, down over the edge of the wall. This dive started at 52-feet, and we quickly descended over the precipice toward the depths. My log entry doesn't have much detail for this dive.

Normally I make notes on my slate during every dive, trying to write down everything my different senses pick up. Then I transfer those notes to my logbook at the end of the dive, adding any little bits of info my memory gives me. But I never find much to write about when I'm diving deeper than 80-feet. Seems to me the coral lives shallower than that. And the most exciting fish play in, and around, the coral. Granted, the big fish (like the larger species of shark) apparently prefer the deeper regions, but I've not spotted many of them. Maybe because I normally stay up around 30- - 70-feet when I dive. Deeper than that the colors fade away from me, and I don't get overly excited in the blandness.
The air in my tank doesn't last near as long either, and I get less time to enjoy those sights I'm underwater for in the first place. My maximum depth on the night dives at Black Rock is 58-feet. All those cool critters that come out at night amaze me. Most of the time at night I feel like it's just the sea life and me. Even though my dive buddy is just a few feet away, all that darkness outside my dive light beam closes me off from the rest of the world.
Some of the pictures I take on night dives are superb. The fish that dart away from you during a day dive lie sleeping, and unmoving, at night. It's like they're posing for your camera. On a normal dive I get maybe one or two decent fish pictures. Most blur from the movement as the subject flits about in the coral. On a night dive I'm more successful, and leave the water with more than half of my shots turning out in focus, and successful additions to my personal photo album.
And those octopuses? I'll always cherish my first octopus experience, and the memory that it happened during a Black Rock night dive.
