Adventure brief
Beneath Avalon’s Fringing Forest: A Guided Kelp Dive at Casino Point
Casino Point Dive Park, tucked beside Avalon’s iconic Casino Building, is California’s first nonprofit underwater park and a prime shore‑diving destination. Here, giant kelp carpets a landscape of rock walls, pinnacles and sandy plains; strict local protections and the island’s distance from mainland runoff mean unusually clear water and a dense, varied community of fish, lobsters, abalone, octopus and other marine life.
Located off the coast of Southern California, Catalina Island offers a unique blend of natural beauty both above and below the water’s surface. Avalon, the island’s charming harbor town, serves as the gateway to one of the most captivating dive sites in the region: Casino Point Dive Park. Recognized as California’s first nonprofit underwater park, this protected marine haven invites divers to explore a sanctuary where kelp forests sway gently, rocky reefs rise dramatically, and sandy bottoms stretch beneath crystal-clear waters. The 1-Tank Guided Kelp Forest Dive is an ideal entry point for adventurers aged 12 and up, offering a two-hour immersive experience into this thriving underwater ecosystem.
Under the guidance of expert instructors, divers navigate through dense kelp canopies that support an abundance of marine life. The towering kelp creates a forest-like environment beneath the waves, where you’ll encounter colorful fish darting through crevices and sea stars clinging to rock formations. This dive spot is prized for its remarkably good visibility and a thriving community of species including Garibaldi fish, nudibranchs, and the occasional curious sea lion. The site’s protection as a nonprofit park has helped preserve its vibrant underwater landscapes, free from pollution, making every dive here feel like a serene escape into nature’s clearest depths.
What sets Casino Point apart is the perfect balance it strikes between accessibility and diversity. Located a short swim from the shore of Avalon, it’s equally welcoming to newcomers and seasoned divers seeking to experience Southern California's marine biodiversity with ease and safety. The water temperature varies seasonally but remains refreshingly comfortable, especially in summer months. The dive is meticulously guided, ensuring participants not only enjoy the sights but also learn about the local ecology, conservation efforts, and the significance of maintaining these underwater habitats.
Avalon’s welcoming atmosphere, combined with the island’s rugged terrain and clear waters, elevates this experience beyond a simple recreational dive. For anyone visiting Catalina Island and interested in outdoor adventure, this guided dive offers an unmatched opportunity to connect with the ocean in a setting that is as educational as it is breathtaking. Whether you’re a beginner or looking to add an unforgettable dive to your logbook, the 1-Tank Guided Kelp Forest Dive at Casino Point provides an exceptional window into a laboratory of marine life right off the California coast.
