We did a total of four dives on Tent Reef with one of the being on a night dive. The visibility was +100 ft, water temp was 83 degrees (f) and almost no current to deal with. The weather was perfect and so was the diving all around Saba.
Did this dive twice in 10 days. The wall is exploding with color, tons of coral, many sponges, and an abundance of wildlife. There are a few coral covered boulders at the southish end of the dive that are very interesting. Highlight of this dive was watching a couple of hermit crabs battling for territory.
Tent reef is actually a collection of about 3 or 4 separate dive sites, ranging from the deep wall to a more novice-friendly shallows. Dramatic drop-offs at the wall with corals as far as the eye can see. Looking out into the open blue, sharks are fairly common, as eel as sea turtles (I saw both on my dive here).
