Overnight Yacht Charter Los Cabos to Cabo Pulmo — 2-Day Itinerary

Why overnight is the only way to do Pulmo properly from Los Cabos

Cabo Pulmo is the Sea of Cortez crown jewel — a 71 km² no-take marine reserve where, since 1995, biomass has recovered an estimated 460%, the highest documented marine recovery on the planet. The reef is one of the few "hard coral" reefs in the eastern Pacific and supports schools of jacks, snapper, the famous bull-shark aggregations and the occasional whale shark. From Cabo San Lucas Marina it is 55 nm one way; from Puerto Los Cabos / San José it is 41 nm. Either is too far for a day-trip-and-back with meaningful in-water time.

Going overnight changes the math entirely. Day 1 you sail east, fish or snorkel along the way, anchor in protected water for sunset. Day 2 you have a full morning of dives or snorkel before turning back. You see Pulmo in calm dawn light rather than rushed midday crowds. For dive-focused guests this is the only honest way to combine yacht charter and Pulmo reef. Read our Cabo Pulmo diving guide for the underwater detail.

Day-by-day itinerary

The schedule moves with weather and group. Captains pad each leg with 30-minute buffers for sea-state and crowd at Pulmo's mooring buoys.

Departure: Puerto Los Cabos is the better starting point

For Pulmo overnight, start from Puerto Los Cabos / San José del Cabo Marina. The 14 nm you save versus Cabo San Lucas is one full hour each way at cruising speed — meaning the difference between arriving at Pulmo with daylight to set anchor and snorkel, versus arriving in dusk. See our marina comparison for the full logistics.

The Capitanía de Puerto in San José issues your overnight despacho (it must declare overnight intent and the anchorage zone). SEMAR rules require this for any commercial vessel leaving for more than 12 hours; it includes a check of safety equipment, VHF radio operability, life rafts, and current crew certifications. Reputable operators handle the paperwork automatically.

Day 1 morning — Gordo Banks fishing or run-through

Gordo Banks is a pair of seamounts 8 nm offshore between San José and the East Cape, sitting at the edge of the continental shelf. The drop from 50 m to 800 m attracts pelagic fish year-round: striped marlin, dorado, yellowfin tuna, wahoo. If your group includes anglers, build in 90 minutes of trolling here on Day 1 morning. If not, push through and save the time for a longer snorkel at Pulmo. See our Los Cabos sport fishing page for tackle and target details.

Conditions at Gordo Banks vary. The Sea of Cortez current accelerates around the seamounts and the chop can be sharp on a Norther day. Captains assess at the waypoint — if the bite isn't on or the sea is bumpy, they push north toward Los Frailes for the afternoon lunch anchor.

Cabo Pulmo anchorage rules — what CONANP actually enforces

Cabo Pulmo National Park is a federally protected no-take zone. CONANP rules are specific and strictly enforced:

• No anchoring on reef. Approved anchorages are sand-only, marked on the park chart. Fine for reef damage: 50,000+ MXN and vessel detention.
• Mooring buoys are first-come at the dive sites (El Bajo, El Cantil, El Vencedor). For yacht overnight you anchor in the designated sand zones north of the main reef — typically off Los Frailes or in the sheltered cove south of the park boundary.
• Day-use fee: ~$10 USD per guest (CONANP wristband). Mandatory.
• No spearfishing, no fishing, no shell collection inside park boundaries.
• No discharge. Holding tanks must remain closed; black-water discharge inside the park is a federal offence.

Reputable charter operators carry a current Pulmo anchorage permit from CONANP. Ask for the permit number before you book — operators that anchor "informally" risk park ejection mid-trip.

Day 2 — morning dive or snorkel at Pulmo

The magic at Pulmo is the early morning — water is glass, visibility 25–35 m, and the big schools (jacks, snapper) are stacked at El Bajo and El Cantil before the day-trippers arrive from the village. If you carry a dive certification, this is when you do the certified dive. If you don't, the snorkel from the surface above El Bajo is genuinely one of the best snorkels in Mexico — you don't need depth to see the schools.

Local Pulmo dive operators (PADI / SSI / NAUI-certified) tender their boats from the village every morning starting at 8 am; you can either hire them direct ($65–90 USD per dive) or your yacht crew may carry rental tanks for certified guests. Our Cabo Pulmo diving guide details site-by-site notes. NOAA ocean data confirms Pulmo as one of the most successful marine recoveries documented globally.

Provisioning, water, fuel and onboard life

Overnight charters provision differently from day trips. The captain or operator will ask you to pre-fill a provisioning list 48 hours ahead: dietary preferences, alcohol selection, breakfast/lunch/dinner preferences. Premium charters include a chef onboard; budget overnights are catered cold/reheat meals from a local provider. Either way, fresh fish caught on Day 1 (if fishing) is usually grilled for Day 1 dinner.

Freshwater capacity matters. A 50 ft yacht typically carries 200–400 gallons; that is enough for 6–8 guests showering modestly. If your group is bigger, ration showers (one per day, short) or upgrade to a 60+ ft with watermaker. Fuel for the round trip from Puerto Los Cabos to Pulmo and back is typically 400–700 litres — invoiced as a surcharge of $400–800 USD. API BCS sets fuel pricing at marina pumps; the operator passes through.

Weather windows — when to actually book

The best overnight Pulmo windows are late April through early June (post-whale season, pre-summer heat) and October–November (post-hurricane, pre-Norther). Both windows give flat morning seas, 26–28 °C water, no swell wrap and reliable Capitanía despatch.

Avoid August–September (hurricane risk, see our season guide) and the peak Norther months (December–February) where the East Cape can be 25+ knots and the anchorage at Pulmo is rolly. The WeatherFlow wind model and NOAA offshore charts are the standard pre-trip references.
