What To Expect
Diving in California can be defined by two words: Kelp. Forest. Kelp forests are home to a variety of species and the kelp itself can grow up to 2 feet per day. The kelp creates an underwater rainforest with a large canopy where sunbeams shine through. The ocean here is home to cool, nutrient-rich water and an abundance of marine life. California has great diving for everyone with large kelp forests and marine life everywhere you look.
