Catalina Island, situated just 22 miles off the Southern California coast, offers an accessible yet transformative escape into ocean blues and rugged island landscapes. Avalon, the island’s only city, serves as the gateway for Catalina Adventure Tours, a standout outfitter providing a suite of immersive experiences that bring the island’s unique terrain and seascape into sharp focus. From beneath the waves to panoramic mountain ridges, this company specializes in bringing visitors face-to-face with island ecosystems both above and below the waterline.
Among their signature offerings, the Inside Adventure Tour provides an insightful dive into Catalina’s marine environment.
