Overview

Passengers board the SS Nautilus, a yellow semi-submarine docked at Catalina Island's Green Pier. The vessel, modeled after the USS Nautilus, offers underwater viewing windows six feet below the surface while keeping visitors dry. The 45-minute tour moves through Avalon Bay to Lovers' Cove, a protected marine sanctuary where guests can press torpedo buttons to release fish food for an extra charge and attract schools of fish close to the portholes. After exploring the underwater gardens, the submarine returns to the marina, allowing travelers to enjoy harbor views from the top deck. Tours run hourly from mid-morning until an hour before sunset, weather permitting. An English-speaking guide is included during the entire journey. Transportation to Catalina Island is not included and requires separate arrangements, typically by ferry via Catalina Express or Newport Flyer.
