Sea of Cortez liveaboards: La Paz, Midriff Islands or Explore Baja?
Choose a Sea of Cortez liveaboard by route: La Paz coastal diving, Puerto Peñasco Midriff Islands or a one-way Baja expedition, with boat and transfer differences.
Choose the Sea of Cortez route before the boat
A Sea of Cortez liveaboard can mean a short southern trip from La Paz, a Midriff Islands week from Puerto Peñasco, or a longer one-way expedition between northern and southern ports. These are different journeys with different flight and transfer plans. A La Paz itinerary does not normally include the northern Midriff circuit simply because both are sold as Sea of Cortez diving. Choose the southern Nautilus programmes for La Reina, Espíritu Santo and route-specific Loreto or Cabo Pulmo diving. Choose Mexico Liveaboards' Midriff programme for Ángel de la Guarda, San Pedro Mártir and Bahía de los Ángeles. Choose Explore Baja if you want a longer north–south journey and can handle different arrival and departure ports.

La Paz: short Getaway, Loreto or Cabo Pulmo?
Nautilus' six-day Getaway has four activity days between boarding and disembarkation. The operator advertises up to 16 dives, with La Reina, El Bajo, Las Ánimas and Espíritu Santo among the possible areas. It is the shorter choice if you do not want a full week aboard. Its eight-day northern programme extends to Bahía de Loreto National Park, naming Coronado, Danzante and Carmen islands. 'La Paz north to Loreto' describes the dive area, not necessarily a one-way passenger drop in Loreto: the published sample returns to La Paz. The eight-day southern programme instead includes Cabo Pulmo, where Nautilus describes two dives with a local operator using a panga. If Cabo Pulmo is the reason for booking, choose that named programme rather than assuming the Getaway includes it. Nautilus advertises up to 24 dives on the eight-day format, subject to conditions, with no diving on boarding or disembarkation days.
Nautilus: Sea of Cortez programme variants and itinerariesMidriff Islands from Puerto Peñasco
Mexico Liveaboards advertises Midriff Islands trips for July through September, with an eight-day, seven-night sample. Day one is boarding in Puerto Peñasco; the route then spends two days around Ángel de la Guarda and two around San Pedro Mártir before Salsipuedes/Las Ánimas and a Bahía de los Ángeles stop. The return is to Puerto Peñasco on day eight. The operator plans whale-shark snorkelling at Bahía de los Ángeles, not a guaranteed scuba dive with whale sharks. Weather, animal presence and actual access can change the stop. Night dives appear in the sample, unlike the Socorro programme. Pick this route for its northern geography rather than assuming the southern La Paz sites are included. Puerto Peñasco is the joining port, not Cabo or La Paz. The destination fare excludes transfers. Obtain the current joining package and a workable journey to that port before buying a southern Baja flight; a generic Mexico liveaboard airport recommendation will not solve this transfer.
Mexico Liveaboards: Midriff Islands itinerary and inclusionsExplore Baja: the one-way expedition
Explore Baja is advertised as 13 days, 12 nights and 11 dive days. The north-to-south sample boards in Puerto Peñasco and disembarks in San José del Cabo, connecting northern islands and Bahía de los Ángeles with Coronado, Danzante, Espíritu Santo and Cerralvo. The reverse programme starts in San José del Cabo and ends in Puerto Peñasco. Choose it for coverage rather than a shorter crossing or a compact week. The operator calls the route a guideline and may change sites. Buy the transport legs to match the specific direction; a return flight through the same southern airport may create an unnecessary transfer from the northern endpoint. Transfers to and from the boat are excluded from the published fare.
Mexico Liveaboards: Explore Baja, both directionsWhich boats and cabins are available?
Nautilus lists Belle Amie, Explorer, UnderSea and Gallant Lady on its Sea of Cortez page. Their advertised maximum guest capacities differ: 32, 25, 19 and 12 respectively. Gallant Lady has six suites; the larger boats have different stateroom and suite categories. The fleet list is not proof that each boat runs each itinerary on your dates. Compare the assigned ship and cabin alongside the route. Mexico Liveaboards uses Rocio del Mar and Quino del Mar, each described as having ten en-suite cabins for 20 divers. Rocio has main-deck twin bunks and queen cabins, plus two upper-deck double-and-bunk cabins. Quino has upper-deck bunk cabins, two upper-deck twin-to-king cabins and two larger below-deck cabins with two queens each. Specify the bed arrangement: 'twin' and 'twin bunk' are different products. Current Quino del Mar specifications should not be replaced by older Quino el Guardian reviews.

Nautilus markets July to November for its southern diving programmes; Mexico Liveaboards markets July to September for Midriff and September to October on its main Explore Baja listing. These are operator programme windows, not a promise of uniform sea conditions throughout the Gulf. Mexico Liveaboards warns of thermoclines and cooler currents even during its warm-water season. For Los Islotes specifically, Nautilus says its programme uses San Francisquito during the July–August breeding closure and describes Los Islotes reopening on 1 September. Treat that as the operator's published seasonal routing, not a guarantee that every departure has access. Do not book a July southern trip on an unconditional Los Islotes sea-lion promise. Nautilus requires Open Water certification, good buoyancy control and proof of certification; it says guides are in the water on all dives. Medical and dive insurance including evacuation cover is mandatory on its published programme. Night diving and some deeper or current-exposed sites still require a suitable individual plan. A broad 'all experience levels' invitation does not certify every site as appropriate for a newly qualified diver, and it does not establish another operator's entry rules.
Nautilus: Sea of Cortez season, site notes and diving requirementsDated fares and excluded costs
Checked on 24 October 2026, Mexico Liveaboards publishes 2027/2028 Midriff fares of US$3,195 per person, double occupancy, and Explore Baja fares of US$5,095 on the same occupancy basis. Both include taxes, port fees, meals, beverages, tanks, weights, and complimentary beer and wine. The listed exclusions include park fees, US$140 Nitrox, transfers and gratuities. Those are published programme fares, not confirmation of an available cabin or an all-in total. Nautilus includes meals, snacks, non-alcoholic drinks, tanks, weights, guides and scheduled group transfers. It lists rental gear, Nitrox, bar purchases, internet, insurance, gratuities and a US$35 cash port fee separately. Its shorter southern trips and the longer Midriff/Explore Baja programmes should not be ranked by headline fare alone: first match nights, dive days, transfers and the actual cabin.
Mexico Liveaboards: Midriff rates and inclusionsLa Paz and Cabo transfer details
For its usual La Paz boarding, Nautilus publishes a 4:30pm group transfer from SeeCreatures Cabo San Lucas, with roughly 2.5 hours on the road. It also lists a 6:45pm transfer from Baja Expeditions HQ in La Paz, plus pre-arranged local hotel pickup. Rental-gear guests joining in La Paz are asked to visit the HQ before 4pm for fitting. These are current sample arrangements; the trip-specific instructions take precedence. The programme page flags exceptions: some late-June to mid-July departures board directly in Cabo, and some October trips disembark there instead of La Paz. For its standard La Paz return it recommends SJD flights at 1pm or later for the road transfer. That is a transport recommendation, not personal clearance to fly after diving. Keep the actual last-dive time and the advice appropriate to your dive profile separate from the airport-transfer timetable.
