Three Tree N offers a straightforward shore dive, popular with local divers for its easy access and a chance to stretch the gills. You'll likely find rockfish tucked into crevices and lingcod patrolling the bottom, often in about 10-20 metres of water. It's a good spot for a relaxed dive, especially for those getting familiar with colder water conditions or testing new gear.
