Adventure Diving & Offshore Expeditions

Two Levels of Adventure

1. Advanced Dives Inside the National Marine Park

These are structured two-dive outings for certified divers whose training, recent experience, and comfort match the selected site. Shared and private prices are published below.

2. Custom Offshore Adventure Expeditions

These are individually planned operations outside the standard park itinerary. They may require longer navigation, additional cylinders, specialized configurations, more support personnel, extended boat time, technical or overhead-environment training, and a site-specific gas and emergency plan. Prices are prepared only after direct consultation.

Wrecks, Drifts, Reefs, and Complex Topography

A National Marine Park adventure outing may focus on wreck diving, deeper reef profiles, drift diving, tunnels, caves, or exposed reef structures. The objective is chosen according to the divers and the actual conditions, rather than selecting a famous name without considering the group.

Conditions may be dynamic. Some sites can involve strong current, faster descents, greater depth, blue-water entries, negative entries, limited reference points, or increased task loading. Every dive is planned and briefed according to the specific site and group.

Wildlife may include turtles, rays, barracudas, lobsters, reef fish, and passing pelagic animals. Seasonal encounters can occur, but marine life and visibility are natural variables and cannot be guaranteed.

Why the Company Is Called Adventure Tours

Adventure Tours Isla Mujeres was not named after a marketing slogan. The name grew from years spent exploring waters that were rarely included on the conventional dive maps used around the island.

Long before many offshore locations were discussed by divers, local fishermen had already navigated those waters for generations. Their knowledge came from current, weather, bottom structure, fishing grounds, landmarks, and experience accumulated at sea.

Over the years, that knowledge became the starting point for exploration. Routes were tested, sites were located, navigation references were organized, and practical dive plans were developed. The result was not a list copied from another dive operation, but an expanding body of local routes built through direct exploration and the experience of people who knew the sea.

That history remains central to the company. Adventure Tours Isla Mujeres offers familiar recreational services, but its identity comes from going farther, planning carefully, and creating access to environments that very few conventional dive operations visit. Read more about the team and operating philosophy on our About Us page.

Custom Offshore Adventure Expeditions

Beyond the National Marine Park lies another level of diving: exposed offshore reefs, walls, caverns, wrecks, isolated structures, freshwater formations below the sea, open-ocean sites, and routes that remain unknown to most visiting divers.

These are not regular two-dive tours. Each operation is designed around the selected objective, distance, expected conditions, diver qualifications, recent experience, gas consumption, equipment configuration, number of participants, support team, boat requirements, surface support, and contingency planning.

Possible offshore expedition objectives include:

• Sleeping Shark Cave
• Ultrafreeze Wreck
• Media Luna
• Pailas
• El Hondureño
• Chairel
• Piedra Atravesada
• Ojo de Agua
• Piedra de la Cherna
• El Cantil
• Piedras Negras
• Fondo Seco
• Cueva del Tiburón Toro
• La Picuda
• Pargos
• Topen
• Los Picos
• Arrowsmith

Publishing these names does not create a fixed menu and does not guarantee that every location can be operated on request. Some objectives require rare combinations of weather, sea state, current, visibility, equipment, personnel, and diver readiness.

Ojo de Agua: Fresh Water Beneath the Caribbean

Known locally as Ojo de Agua, this is one of the most unusual offshore environments associated with Isla Mujeres. Fresh water emerges beneath the sea through a submerged geological formation, creating a visible connection between the peninsula’s underground water system and the Caribbean.

The entrance is located at approximately 100 ft / 30 m. Beyond it is a restriction leading into an overhead environment. This is not presented as a casual recreational attraction. Any objective involving entry beyond the open-water area requires the appropriate technical or cave training, suitable equipment, disciplined gas planning, redundancy, and a separately approved expedition plan.

Depending on the objective and diver qualifications, doubles or sidemount may be considered. Equipment configuration is determined only after reviewing the complete team, route, gas requirements, boat support, and conditions.

Arrowsmith: The Offshore Frontier

Arrowsmith is not a routine extension of an Isla Mujeres dive day. It is a large offshore submarine plateau located far east of the island, in open water where navigation, weather, current, sea state, vessel endurance, support, and contingency planning become central parts of the operation.

For Adventure Tours Isla Mujeres, Arrowsmith represents the far end of the expedition spectrum: a remote objective that must be approached through preparation rather than enthusiasm alone. The appropriate dive plan depends entirely on the selected area, the team’s training and experience, the expected profile, available gases, equipment, support personnel, and conditions.

An Arrowsmith request begins with a direct technical and logistical consultation. It is never confirmed as a standard tour and no departure is guaranteed until the complete operation has been evaluated.

Los Picos: An Exceptional Adventure Objective

Alongside Arrowsmith, Los Picos is one of our most exclusive and demanding expedition objectives. Depth and current make this a serious undertaking, not a routine reef dive or an automatic option for anyone holding an Advanced certification.

Every request begins with a review of recent diving, relevant experience, the intended profile, equipment, gases, vessel support and conditions. Where a profile requires technical training or equipment, those requirements must be met before the operation can be considered. We do not publish a fixed depth, departure or wildlife guarantee.

Explore Los Picos on our illustrative map or request a personal expedition consultation.

How an Offshore Expedition Is Planned

Every request begins with the divers, not with a price list. Before proposing a site or configuration, the team reviews:

• Certification level and relevant specialties.
• Technical, wreck, cavern, cave, decompression, or sidemount qualifications when applicable.
• Number of logged dives and recent diving activity.
• Previous experience in current, blue water, depth, wrecks, overhead environments, or open ocean.
• Personal gas consumption and planned breathing gases.
• Backmount single, doubles, sidemount, stage, or decompression-cylinder requirements.
• Personal and rental equipment requirements.
• Expedition objective and acceptable alternatives.
• Distance, navigation, fuel, boat time, and surface support.
• Number of dive professionals and support personnel required.
• Weather, current, visibility, sea state, permits, and protected-area restrictions.
• Emergency, lost-diver, gas-sharing, surface, and evacuation considerations.

The final plan may be simpler or substantially more complex depending on the objective. No equipment configuration, gas, depth, penetration, or decompression profile is implied merely because a site name appears on this page.

Offshore Expedition Pricing

Offshore expedition prices are not published because no two operations are identical. The final cost depends on the selected objective, distance, vessel and fuel requirements, duration, number of divers, professional and surface-support personnel, cylinders, breathing gases, equipment configuration, logistics, and any additional safety or transportation requirements.

A quotation is prepared only after the diver profile and expedition objective have been reviewed directly. Contact us through WhatsApp to begin an expedition consultation.
