Low. Must be able to climb into a small hatch and sit for the submersion period.
Pilot a compact submarine off Cozumel and glide over the Mesoamerican Barrier Reef without scuba certification. This one-hour Mini-Sub Dive Tour delivers close encounters with coral gardens and reef fish plus practical access from a beachfront resort.
You meet on a bright strip of sand at Hotel Cozumel & Resort, where the Caribbean hums just beyond the palms. The mini-sub sits half-in and half-out of the shallows like an odd mechanical creature—compact, rounded, and finished in safety-orange. After a quick, bilingual briefing a guide helps you settle into the five-person cabin. The hatch seals with a soft clunk, the sub settles, and the ocean seems to draw you down with a steady, patient pull.

Plan to be at the resort lobby at least 15 minutes before your start time to complete paperwork and safety briefing.
The tour excludes guests with recent surgery, certain chronic conditions, and pregnant travelers—review health rules before booking.
Apply biodegradable, reef-safe sunscreen before arriving to protect coral from harmful chemicals.
If you get queasy on boats, take a preventative medication or use acupressure bands; the sub is stable but transfers from boat can rock.
Cozumel has long been significant to the Maya and later grew into a modern dive hub after mid-20th-century explorers documented its clear waters and abundant reefs.
The island participates in reef-monitoring and restoration projects; operators emphasize no-touch policies and reef-safe products to minimize impact.
Protects coral and reduces skin exposure during pre- and post-dive time on deck.
