Christmas tree worm

There are four caves you won’t want to miss here. The Hourglass Cave is just to the land side of the F1 buoy. Wait until you see this thing. It really does look like an hourglass. The Christmas Tree Cave is on the land side of the F3 buoy. It’s cloaked with Christmas tree worms. This cave is at least 3 ½ feet tall and 20' long. There’s enough room here for you to swim thru. At the F5 buoy there’s this sandbank that has coral ridges all around it. There’s another easy swim thru cave at the F6 buoy. A cave called White Sand Bottom Cave is the largest one here and it’s located right in the center of this reef. Yep, you guessed it, there’s white sand covering the bottom of this cave. On the land side of the F7 buoy is a spectacular ledge. About 90 feet northwest of it is an old coral encrusted anchor. At the south end of the reef are a bunch of slender caves, this area is called Five caves.

The limestone walls are a beautiful site to see. There are canyons, crevices, sponges , corals and large schools of fish living here. This is a fabulous site for underwater photography.
