Aldora Divers is a long-established Cozumel dive operator focused on personalized trips for certified divers, scuba instruction, specialty experiences and dive-and-stay planning. Its approach is built around small groups, fast boats and high-pressure steel tanks that give properly prepared divers more gas options and unhurried dive profiles.

What makes Aldora’s approach distinctive

The company describes groups of no more than six divers, matched by gas use, experience and interests. It advertises 80-, 100- and 120-cubic-foot high-pressure steel tanks and computer-aided multilevel dives averaging around 70 minutes. Actual bottom time always depends on consumption, depth, conditions, the guide’s plan and safe limits.

Certified diving, courses and special trips

Aldora lists daily two-tank outings plus twilight and night diving for certified guests. It also promotes northern, east-side and other specialty dives, including blackwater diving for suitably qualified guests.

Level	Programs listed

Specialty dives can carry experience, insurance or skill prerequisites, so share your recent dive history when you inquire.

Who may appreciate this operator

Aldora suits certified divers who want smaller groups and a team that organizes boats around experience and air use, and new divers can start with its training programs. Mixed-experience parties can ask whether they stay together or split into groups. Private charters are available for a dedicated itinerary, though reef choice remains subject to marine-park rules, weather, port conditions and the captain’s judgment.

Planning a Cozumel dive day

Have your certification details ready and be honest about when you last dived; a refresher may be recommended. Ask which equipment is included and whether enriched air requires proof of certification. The shop advertises equipment care between diving days, and divers bringing their own gear should still inspect it before use. Currents, wind and harbor decisions can change site selection or keep boats in port, so build flexibility into your plans.

Getting there

Aldora operates from a downtown Cozumel base, and its official material mentions pickup possibilities from selected hotel-zone docks and partnerships for dive-and-stay packages. Travelers staying on the mainland should allow ample time for the ferry and local transport; staying on Cozumel removes several moving parts from a dive day.

Before you book

Dive prices, schedules and inclusions change. Before paying, confirm the date, the total price and deposit, equipment and marine-park charges, the pickup point, whether dive accident insurance is required, and the weather and cancellation terms with the shop.
