Beach-entry training dive with a light-filled opening.
Senma Dragon Hole is a beach-entry dive with a very shallow start and a short swim to a light-filled opening that gives the site its dramatic look. It works well as a relaxed training dive, with easy logistics, a sheltered feel, and a profile that stays friendly while still feeling distinctive. Turtle sightings are the main draw, with gray reef sharks as an occasional bonus.
