I went there back in 2005. I’m sure it’s changed some since then.. I did my first ever dive (discover scuba) there with Dive Safaris. They took us to this bay that had some old cannons and, if I remember correctly, a small wreck.. They sunk a little yellow submarine during our dive that day. All this was only about 30-35 feet, but it was enough to hook me on scuba diving for the rest of my life. Hopefully someone that has had more experience there will post here for you..
