February - March


Our winter trips to Guerrero Negro offer you a once in a lifetime experience to get up and close to a gray whale and maybe even a newborn calf. These curious creatures often come up to the panga boats within arm’s distance or even closer! Here you will have an optional scientific research training in data collection surveys. Surveys are used to help. monitor the whales’ health and well-being, population abundance, distribution, and more. You can also observe our marine biologist guides conduct their own research by documenting the behaviors of gray whale mother and calf pairs by drone.


Guerrero Negro is one of the winter homes for gray whales. These majestic animals migrate thousands of miles down the Pacific Coast to reach the warm waters of the Baja nursing lagoons such as Ojo de Libre (Scammons Lagoon). Here, they breed and give birth to their young before heading back to their Arctic feeding grounds. The area of Guerrero Negro, meaning “Black Warrior,” is located halfway down the Baja peninsula along the Pacific Coast. This desert coastal town is also known for its ecotourism and salt production.

Day 1: This will be our travel day. Guerrero Negro is located 11 hours south of San Diego (800 km/500 miles) along the Pacific Coast and the Sea of Cortes. While driving down Baja California, we will pass through sweeping desert and ocean views before arriving at our relaxing hotel. We will stop for lunch at San Felipe, home of the endangered vaquita.


Days 2-4: Gray whale excursion days!. Day 2 will only have one boat tour, while days 3 and 4 will have two boat trips per day, for a total of 5 boat trips per expeditions. Each boat tour is around 3 hours, so you will be spending roughly 3-6 hours on the water each day looking for gray whales and other marine life! In addition, we will visit the mirror-like salt flats at sunset to admire an amazing landscape and you will also have the opportunity to take an optional tour on world's largest salt operation company.
