The Channel Islands off Southern California offer a diving experience unlike any tropical destination — towering kelp forests that filter golden light, playful sea lions that spiral around divers, and rocky reefs teeming with giant sea bass and colorful invertebrates. The national park's protected waters are a temperate diving paradise just an hour's boat ride from Ventura. Cold water rewards those who come prepared with drysuit-worthy encounters.
