Magic Island Lagoon

Enter via a 1'-wide mini-beach at the near-left (east/Waikiki) side of Magic Island. Magic Island is the circular artificial pool at the end of the peninsula on the east side of Ala Moana park. Here's where the prior descriptions of the dive have been vague: The entry is onto ankle-deep coral/rock. Going southeast from the beach, you soon find a shallow (10'/3m deep) wall. On the deeper side is a silty boat channel. Follow this wall out to sea for about 20 meters, then hop over the wall and swim westward a few feet. If you don't make this all-important move, you'll get bored to death in a lifeless silty boat channel. Once you've swum westward a bit, you'll find yourself in clean 30'/10m deep coral canyons with good viz and a bottom made of broken corals instead of silt. Go seaward as far as the tall channel marker, and you'll surely see at least one green sea turtle. On your way back, retrace your route and pop up to the surface occasionally to make sure you're on the right path. Unsuitable as a night dive, imho, because it's too easy to misplace a buddy and become disoriented in the silt, or by the twisting/turning paths through the shallow canyons.
