Socorro
Socorro sits within the Revillagigedo Archipelago, a cluster of volcanic islands roughly 390km south of the Baja California peninsula, reachable only by a 24-hour liveaboard crossing from San Jose del Cabo. Giant oceanic manta rays are resident year-round at cleaning stations like The Boiler and Cabo Pearce, while humpback whales pass through January to March and whale sharks are most reliably seen November and December. The whole archipelago is a UNESCO World Heritage Site and Mexican national park, with diving restricted to a licensed liveaboard fleet.
What makes it special
- One of the few places where giant oceanic manta rays (Mobula birostris) are reliably resident at cleaning stations year-round
- UNESCO World Heritage Site (inscribed 2016) and Mexican national park (declared 2017)
- Roca Partida is a pinnacle jutting from 50m+ of open ocean, ~40km from Socorro Island, known for stacked whitetip reef sharks and schooling hammerheads

Trip type
Liveaboard
Price is per person for a typical trip, excluding international flights ($$ $2,000–4,000 to $$$ over $4,000).
Roughly $2,955-3,935 per person for 8-11 nights on most operators, up to $5,729 on longer premium trips. Marine park fees (~$800-860) and the international flight to Los Cabos are additional. No land-based or budget alternative exists — this is a liveaboard-only destination.
Best time to dive
- Current
- Strong
- Water temp
- 21–29°C (coldest Jan, warmest Jul)
- Getting there
- Demanding — Liveaboard only, with a 26h open-ocean crossing to reach the diving.
- Experience
- Most operators require Advanced Open Water certification plus 50+ logged dives, given strong currents and deep, open-ocean pinnacle dives. A confident, well-guided beginner can sometimes join, but this varies by operator.
Nearest airports
- SJD — Los Cabos International Airport (San Jose del Cabo) (Direct international flights; liveaboards depart from San Jose del Cabo or Cabo San Lucas after a 24-hour open-ocean crossing to the islands)
Permit required
Diving is restricted to a limited number of licensed liveaboards operating within Revillagigedo Archipelago National Park (established 2017); independent or non-liveaboard access is not permitted.
Roughly $195 per diving day (3,622 MXN), doubled from ~$97 effective 1 January 2025 — about $1,170 for a typical six-diving-day trip, charged on top of the liveaboard fare. Fees have risen sharply and are pesos-denominated, so confirm the current amount at booking.

Most operators report November-December as the strongest window. At least one operator instead emphasizes April-May, particularly on the season's final trips — genuine disagreement between sources, treated conservatively here.

Dive sites
Worth knowing before you book
- Liveaboard-only — there is no land-based or budget alternative, and trips run 8-11 days minimum.
- Getting there means a 24-hour open-ocean crossing each way from San Jose del Cabo, which can be rough and is a genuine consideration for seasickness-prone divers.
- The park is only open November through May; it closes for the rest of the year due to weather.
- Sources disagree on exact whale shark timing (November-December per most operators, versus April-July per at least one) — a reminder that pelagic sightings here are inherently less predictable than reef diving.
- Trips fill 9-12 months in advance, especially for the January-March whale season.

Note on the data: Whale shark seasonality is a genuine source conflict (see knownTradeoffs) — see the whale-shark sighting record for how this was resolved. Region center coordinates are an approximation (roughly midway between Socorro Island and Roca Partida, which are ~110km apart) since there's no single population center to anchor on; consider whether the map should instead show a pin per island. Price range reflects 2025/2026 quoted rates from a small sample of operators, not a systematic survey. Water temperature: The Nov-May dive season runs warm at the start (26-28C in Nov-Dec) and coolest in Jan-Mar (roughly 20-24C); the warmer Jun-Oct figures are the summer surface peak but the archipelago is effectively closed then for hurricane season, so those months are interpolated from seasonal data rather than dive reports. Access: Liveaboard-only: fly into Los Cabos (SJD), transfer about 45 minutes to the Cabo San Lucas marina, then cross roughly 320nm of open Pacific in a 24-30 hour passage (commonly cited 24-28h) to reach the Revillagigedo dive sites.
