Guided Scuba Dive at Casino Point — Explore Catalina’s Kelp Forest in Avalon, CA

Casino Point Underwater Park sits off Avalon on Catalina Island, California, and the Guided Scuba Dive offered by Catalina Divers Supply delivers two hours inside one of Southern California’s richest nearshore ecosystems. The entry is at Catalina Divers Supply on Avalon’s shore; from there a seasoned divemaster guides certified divers through towering Macrocystis kelp, sculpted rocky ledges and walls where more than 800 species make their home. This guided dive is ideal for solo certified divers who want orientation, and for those returning after a gap—the shop recommends a private refresher or a Reactivate course for divers inactive several years. Expect low boat time and easy shore or short-boat access into the Casino Point Park, a protected marine area with clear water, good visibility and gentle currents on most days. The instructor-led format focuses on species ID, safe navigation through kelp, and buoyancy skills among Garibaldi, kelp bass, rockfish, and an occasional hornshark or bat ray. What makes this site distinctive is the dense kelp canopy—giant kelp (Macrocystis pyrifera) drapes column-like stipes that create vertical corridors for fish and invertebrates—and the blocky volcanic and metamorphic rock outcrops carved by wave action. That structure concentrates life: colorful nudibranchs, encrusting sponges and dense schools of forage fish. Casino Point also has historical ties to Avalon’s shoreline development; the nearby Catalina Casino, a 1929 landmark, looms above the harbor and signals how long humans have made this bay a gathering place. Practical notes: bring proof of certification, swimsuit and towel—Catalina Divers Supply can outfit you with all rental gear. If it’s been over two years since your last dive, opt for the suggested refresher; if over three years, consider the Reactivate course. Water temperatures range seasonally; a 7mm wetsuit or drysuit options are sensible in cooler months. The guided format makes this trip accessible to intermediate divers, while still rewarding for advanced photographers and marine-life enthusiasts. Why book it when visiting Avalon? Casino Point is one of the best shore-access dive parks in Southern California: compact, protected and biologically vibrant. A two-hour guided dive maximizes underwater time while minimizing logistics, and a local shop like Catalina Divers Supply offers regional expertise that deepens the experience—identifying species, pointing out microhabitats and keeping safety first. For anyone visiting Avalon who wants an efficient, wildlife-rich scuba experience, this guided dive is a direct route into Catalina’s kelp forest. Bookings are available through the Catalyst referral link provided by the outfitter; small groups ensure personalized attention, and beginners should inquire about a try-dive or discover-scuba option if they lack certification. Allow extra time to walk Avalon’s waterfront before or after your dive to absorb island light, snack on local seafood, and swap sightings with your divemaster. Cheers.
