Regsister HereeA Good Fit for Divers Who Want a Full Day in the Water.
Certified divers of most experience levels
Mammoth Lake’s varied depths give newer divers plenty to explore in the shallows while more experienced divers can push toward the deeper attractions. Open Water certification or higher is expected.
Divers who like a site with a story
This isn’t a reef dive. It’s a lake full of deliberately placed structures built for training and exploration. If you like a dive with things to find, this is a good one.
A low-pressure way to try an Aquanauts event
It’s a full day, a fair drive, and a genuinely fun group. A common first event for divers checking out the Austin Aquanauts before deciding whether to join.
A Day Built Around Exploration, Not a Schedule.
Mammoth Lake is privately operated and set up specifically for divers, with training platforms and staged attractions spread across more than 60 acres. Expect two dives over the course of the day with a break for lunch in between. Visibility varies with depth and recent weather, generally 5 to 45 feet, so bring a light if you want to get a good look at the details on the C-130 and the smaller staged wrecks.
This is a day trip, not an overnight, so plan for the drive down and back on the same day. Exact meeting time and carpool coordination are shared closer to the event date through the Austin Aquanauts calendar.

Familiar Faces Make a Long Drive Worth It.
A day trip like this is a lot more fun with people you already know. Tom’s and the Austin Aquanauts have been building that community since 2013, so you’re never diving with total strangers.
No membership required to come
Members pay a lower price, but this event, like most on the calendar, is open to any certified diver who wants to join.
The group knows the site
Plenty of Aquanauts have dived Mammoth Lake before and are happy to point out what’s worth seeing and where.
One stop on a full year of events
Mammoth Lake is one of several day trips the club runs each year, alongside weekly local dives and social events.
Since 1982
The Austin Aquanauts operate out of Tom’s Dive & Swim, Austin’s dive shop since 1982, so questions about gear, certification, or the event itself have somewhere to go.
Frequently Asked Questions
No. Non-members are welcome at the non-member price. Many divers try Mammoth Lake before deciding whether to join the club.
