I have dove at Provo on Turks & Caicos and I have dove all three cayman Islands. Of the four, the ones with the most to do topside would be in this order:
1. Grand Cayman (town, barefoot music/turtle farm/pirate parafernalia/blow holes/ect
2. Provo Turks & Caicos (sea kayaking/conch farm/restaurants/ect)
3. Cayman Brac (the bluff/caves/ect)
4. Little Cayman ( bird watch/
On Turks and Caicos, I have been out with Big Blue and Caicos Adventures and I prefer Caicos Adventures. The only diving better than T & C IMHO would be Little Cayman and I have used Little Cayman Beach Resort.
The best diving is :
1. Little Cayman
2. Turks & Caicos
3. Cayman Brac
4. Gand Cayman
The best beaches are :
1. Turks and Caicos (Grace Bay area)
2. Grand Cayman (Seven Mile Beach area)
3. Cayman Brac (public beach and west end by the airport)
4. Little Cayman (point of sand)
