On my first trip to Negril, while snorkeling off the cliffs of Blue Cave Castle, I found a real gold chain with a gold Egyptian anch pendant on it at about 30 feet deep. I had fun trying to get it...lol.....but I did. My wife wears it regularly.
I've seen some awesome things scuba diving in Negril. I've scuba dive after several tropical storms and hurricanes and found lots of hotel stuff out to sea. Billiard balls, ceramic tiles, silver cups.......and lots of trash that I picked up. On a night dive I saw TWO sea horses. The divemaster, Armin, said he had waited 10 years to see a seahorse on a night dive and we saw TWO! You wont see them during the day. I've seen monster lobsters, octopus, turtles, eals, etc. Nothing really that I havent seen elsewhere.......other than the seahorse. That was the only time I've ever seen a sea horse.
I'll post some cool photos later :-)
