Hop aboard Catalina Adventure Tours for daily island adventures—by land and sea! Dive into the deep (without getting wet) on the Nautilus, a bright yellow semi-submarine with fish feeders at every window and views 10 feet below the surface. It’s like scuba diving... minus the wetsuit. Prefer the wild side? Their open-air land tours take you off the beaten path to spot bison, bald eagles, and jaw-ping island views. Whether you're cruising underwater or roaming the hills, Catalina Adventure Tours brings the island to life—one epic view at a time.
