Isla San Marcos and Santa Rosalía, BCS

Mar 06, 2018 - National Geographic Sea Lion

Today the colors of the sunrise were incredible, on the East the sun coming up and at the West, pink colors both at the sky and at sea were just marvelous, as the announcement of a great day. Our first stop was at Isla San Marcos, where we had the opportunity to stretch our legs in hikes or along the shoreline. There were also expedition landing craft cruises and one of the highlights of the day was a group of bottlenose dolphins that played close to the expedition landing crafts for a good time. Isla San Marcos is one of the few islands in the Sea of Cortes, where people live and works mining the gypsum which is an important component of the minerals of the island. In the afternoon, we visited another mining town (copper) at Santa Rosalia on the Highway 1 at the Peninsula, where we had the opportunity to taste some flavors of sweet bread at the world famous “Panaderia del Boleo” (Bakery of El Boleo) and also enjoying the view of the town from the Hotel Frances.
