Magic Island Lagoon

Decent dive, year-round. Bring a cart and a landlubber to watch the cart & sun himself, while you're underwater, so you don't have to lug your gear from the car across the paved path to the entry. FORGET a swim-entry through the pool-wall's barrier: the pool's always silty (despite the amazing viz in the photo on this page), and the openings in that barrier are almost always too shallow. The entry beach is sand, but then you're walking on fairly sharp coral/lava, so wear tabi-type boots. Follow the boat harbor channel wall outward to the tall, metal channel marker pole, and you often see 4 turtles there. Depths top off at 30~35'. Rare checkered cowries are here. Occasionally silty rainwater creates a "ceiling" of brown on the surface, but underneath, the seawater's still clean. Not a great night-dive, as conditions can often be muddy-viz and divers can feel lost in the coral canyons.
