Revillagigedo (Socorro Islands)

CONANP lists an entrance fee charged per person, per day inside Revillagigedo National Park. Recent published values are in the range of a few thousand pesos per day (for example, MXN $3,760 per person per day on the Spanish-language park listing). In practice, most liveaboards collect the fee from guests during check-in or onboard, then handle payment to the park authority. Because fees can change and some discounts or exemptions may apply, confirm the exact amount and payment method with your operator before departure.

Socorro is best for divers who are comfortable in blue water with current. Many operators recommend Advanced Open Water (or equivalent) and solid experience with drift diving, deep profiles, and live boat pickups. Even though park rules commonly cap depth at 35 m, the bottom is often far below you and conditions can change quickly, including surge and occasional downcurrents. If you have around 50 dives and can maintain buoyancy without touching the rock, you will usually enjoy the trip more and create fewer problems for the group.

Water temperature varies by month, but a common planning range is about 20°C to 28°C across the season. Many divers are comfortable in a 5mm wetsuit year-round, then add a hooded vest in cooler months, especially if doing 3 to 4 dives per day. Wind on deck between dives can also chill you more than the water does, so pack a light windbreaker. If you run cold or are visiting in spring, err on the warmer side so you can stay focused during long cleaning-station waits.

Snorkeling and freediving are possible but not the primary draw. Conditions are open-ocean with swell and current, so any snorkeling or apnea sessions are guided, conservative, and at the discretion of the captain and dive team. Some liveaboards offer limited surface sessions when seas are calm, and a few trips may include controlled evening snorkeling near the boat. If snorkeling or freediving is your main goal, treat Socorro as a bonus and add Baja California Sur days (La Paz, Cabo Pulmo) for calmer, more consistent shallow-water options.

Think wildlife-first and low impact. Park guidance emphasizes: do not touch, ride, harass, or feed animals; keep at least 2 m from the bottom and rock formations; and maintain respectful distances during encounters. For mantas, guidance includes staying about 3 m away and never cutting across their path. For dolphins, do not chase; hold position and let them choose the interaction. Operators also brief limits like max depth 35 m, max 60 minutes, and small guided groups.

The crossing is a long open-ocean transit, and sea state can vary widely. Even strong divers can get seasick on the first day out. If you are prone to motion sickness, start medication the night before departure (or as directed on the label), and keep it consistent through the first 24 hours. Choose a mid-ship cabin if you can, hydrate, and avoid heavy alcohol or greasy meals before the boat leaves port. Once you arrive, conditions often feel steadier when the boat is anchored in the lee of an island.

There is no chamber on the islands, and evacuation takes time because you are far offshore. On the mainland, Cabo San Lucas has recompression capability through established hyperbaric providers used by the dive community. Your liveaboard will have an emergency action plan and typically carries oxygen and first-aid equipment, but you should treat the trip as remote diving and stay conservative. Carry DAN (or equivalent) dive accident insurance and save the DAN Emergency Hotline number (+1-919-684-9111) in your phone before you leave shore.

Most itineraries revolve around a few classics. The Boiler (San Benedicto) is famous for repeated manta passes at a cleaning station. Roca Partida is the dramatic offshore pinnacle where you can watch sharks and schools of jacks in constant current. Around Socorro Island, Cabo Pearce and Punta Tosca add manta action plus frequent dolphin encounters and seasonal hammerhead chances. Exact site selection depends on conditions and the captain's plan, but these names show up on most trip reports and should be on your must-dive list.
