Discover Cozumel’s underwater world aboard a real submarine. Enjoy stunning coral reefs, vibrant marine life, and a safe, family-friendly adventure for $99.

If you’re looking for a unique way to experience the beauty of Cozumel’s marine environment without getting your face wet, the Atlantis Submarine tour might just be your cup of tea. This expedition takes you about 100 feet beneath the ocean’s surface in a real, US Coast Guard-certified submarine—no snorkel or scuba gear required. It’s a great choice if you want a slice of adventure that’s comfortable, educational, and full of spectacular views.
What we love most about this tour is how it combines intimate, close-up views of vibrant coral reefs with the practicality of a tour designed for all ages and comfort levels. Plus, it’s a quite affordable way to see marine life without the hassle of dive gear or boat rides that can be long and tiring. The only consideration? The tour lasts about two hours, but the actual underwater part is around 45 minutes, so if you’re after a full day of activities, it’s good to plan around this.
This experience suits travelers who are curious about marine ecosystems, families with kids (minimum age 4), or anyone who prefers a gentle, safe adventure over strenuous water sports. If you’re not comfortable with heights or have mobility concerns, be aware that you need to navigate a 12-step ladder and sit comfortably for the ride. But if the idea of seeing the underwater world from an air-conditioned, glass-windowed submarine appeals, this tour offers fantastic value and memorable sights.
