Chamber Tours

USC Catalina Hyperbaric Chamber

Tours of the USC Catalina Hyperbaric Chamber are available at no charge (although donations are greatly appreciated).

If you are planning on being in the Two Harbors / West End area* of Catalina Island and would like to set up a tour of the Chamber please contact us at or 310-510-4020 at least a couple days in advance.

Tours of the Chamber generally last between 30-60 minutes and may be cancelled at the last moment if the Chamber is needed for a treatment.

You can either walk from Two Harbors (~ 2 miles / 3.2 km) or take a shoreboat to the USC Wrigley Marine Science Center where the Chamber is located. If you plan on arriving on a commercial Dive Boat or your own personal boat we may need to have you put your boat on a mooring while you are on shore.

*Please be aware that the village of Two Harbors is about 25 miles (40 km) from the city of Avalon. There are limited transportation options across the island and one-way travel can range from 1-2 hours.
