Kayaking the Sea of Cortez: La Paz, Loreto, Sea Lions, and Whale Sharks

The Sea of Cortez (or Gulf of California) is one of the best places in the world to paddle among desert islands, swim with sea lions, and see whales. The phrase "the world's aquarium" is attributed to explorer Jacques Cousteau, and although we couldn't find the original quote, it is true that its islands and protected areas have been a UNESCO World Heritage Site since 2005.

The Essentials

• Where: Baja California Sur: La Paz, Isla Espíritu Santo, Loreto, and Bahía Concepción.
• Best time for kayaking: October to mid-November, thanks to the warm water and weather. The strongest winds blow from December to February.
• What to see: sea lions, whale sharks, blue and gray whales, dolphins, and mobulas (flying rays).
• Level: guided kayak trips are suitable for beginners.

The Best Spots

• La Paz and Isla Espíritu Santo: departures from the La Paz marina, 45 to 90 minutes. At Los Islotes there is a sea lion colony you can swim with, from mid-October to late May.
• Loreto (Bahía de Loreto National Park): islands such as Carmen, Danzante, and Coronado, and the area known as the "Blue Triangle" for its whales.
• Bahía Concepción (about 25 km south of Mulegé): calm waters and coves. The wind picks up in the afternoon, so it's best to head out early.
• Isla Cerralvo (Isla Jacques Cousteau): off La Ventana and El Sargento, with sea lions, dolphins, and mobulas.

Wildlife and Seasons

Dates vary each year depending on the weather and the operator. Book with a local operator and confirm the season.

Rules for Swimming with Wildlife

• Whale shark: life jacket required, no touching, no flash, and no scuba tanks. A maximum of 5 swimmers and one boat per shark, and visits of up to 2 hours. Operators need a SEMARNAT permit.
• Sea lions (Los Islotes): only in designated areas, with a licensed guide. Visitors keep a distance of about 15 meters from the island, and snorkeling lasts a maximum of an hour and a half.
• Whales: the Mexican standard (NOM-131-SEMARNAT-2010) prohibits physical contact and requires approaching slowly, at under 4 km/h and at a prudent distance.

Operators with Verified Websites

• Baja Expeditions (La Paz): whale shark and sea lion swims from US$125 per person (minimum 4 people), plus kayak trips. Phone +52 612 125 3828.
• Sea Kayak Adventures / ROW Adventures: operating since 1979. They offer trips in Loreto, La Paz, and Bahía Magdalena; the La Paz trips with panga support, 4 to 5 days, cost about US$1,730 to 2,190 per person.
• Sea Quest Kayak: blue whale kayak trips in Loreto from about US$1,799.
• Indómito: adventure and kayak trips in the area.

Many tours do not include the protected-area fee. Ask before you book.

Protected Natural Area Fees

The figures we found don't agree across sources: admission to Espíritu Santo appears at between 150 and 215 MXN, and Loreto at about 90 MXN. There is also an annual Conservation Passport for 3,760 MXN. Confirm with the National Commission of Natural Protected Areas (CONANP) before you travel.

Gear and Fitness Level

• Operators usually provide tents, dry bags, snorkel gear, and tandem kayaks.
• You bring quick-dry synthetic clothing, a hat, water shoes, and reef-safe sunscreen. A long-sleeved shirt helps with small jellyfish.
• You paddle about 4 hours a day. You need balance and flexibility to get in and out of the kayak and to help carry them.
• Recommended minimum ages: 9 with ROW and 14 with Sea Quest.
• Get travel insurance with medical evacuation and trip interruption coverage.

Getting There

• La Paz (LAP): about 20 minutes from downtown. There are flights from Los Angeles, Guadalajara, Mexico City, and Tijuana.
• Loreto (LTO): about 10 minutes from downtown, with few flights.
• Los Cabos (SJD): the airport with the most connections. From SJD to La Paz it's about 3.5 hours by shuttle (from about US$40 to 50).
• Day tours in La Paz: about US$100 to 150 with lunch.
