Mysterious ocean tunnel leads to 4 mile deep drop off

High Rock Drop Off is located on the East end of Grand Cayman Island in High Rock dive zone. These divers from Canada experienced some incredible diving while on Grand Cayman and mostly were amazed and surprised by the number of tunnels and channels that lead out to the "deep blue'. Most of these tunnels are narrow and with limited light from above, require dive lights to make your way through. Feeling a bit uneasy at seeing no bottom once they exited the tunnel, they soon got use to the new experience. A great dive location and many new lessons learned.
