American Safari Cruises will base the refurbished 86-guest Safari Endeavour in Mexico’s Sea of Cortés this winter. The ship will operate weeklong voyages roundtrip from La Paz, Baja, Mexico, from November through April. Guests booking by Sept. 30 get a $300 travel credit per couple for travel through April.

An unstructured itinerary explores hideaways such as Isla Espíritu Santo, Isla San Francisco, Bahia Agua Verde, Los Islotes and Loreto. Flexible itineraries seek out dolphins and blue, fin, sei, orca and sperm whales. At Los Islotes, guests can snorkel among sea lions. Activities include hiking, kayaking, paddle boarding, snorkeling and skiff excursions. The vessel has a swim step and kayak launch platform on the stern of the vessel.

Cruise fares start at $2,995 per person, based on double occupancy. Transfers are included from either Los Cabos or La Paz airports. The inclusive cruise includes all from-the-yacht activities and equipment; a massage; fine wine, premium spirits and microbrews; and all port charges, taxes and fees.
