Descend 48 feet below the surface of San Lucas Bay aboard a purpose-built yellow semi-submersible vessel to observe Pacific marine life and dramatic underwater rock formations in their natural habitat. This unique vantage point combines the thrill of submarine exploration with the comfort of a climate-controlled cabin, making it accessible for all fitness levels.
The Beatles once sang that we all want to live in a yellow submarine. And although this submarine isn't offering any “liveaboard” options, its owners are happy to welcome day-trippers on their 60-foot yellow semi submersible for some of the best sightseeing in all of San Lucas Bay.
