Coronado Island is the island to the North and a very popular destination for day trips. It is a 25-35 minute boat trip from the Marina. The shallow water along the shore is a beautiful turquoise color and a popular site for snorkelers and divers of all levels. The white sandy beaches are ideal for a stroll and a picnic. Shade palapas and a primitive toilet on the main beach. Several local tour companies have trips to these islands or just stroll down to the marina where several Captains will be available to take you out!
There are many fabulous dive destinations around the islands of Coronado, Carmen, and Danzante. The Sea of Cortez has an amazing array of fish and marine animals. If you are not a diver, snorkeling is wonderful in many places where water is less than 20 feet deep. You can sign up to get PADI certified too! Just around the corner:

From January to April, the Gray whales calve in the protected Lagoons near Guerro Negro,San Ignacio, Lopez Mateo, and Magdalena Bay on the Pacific side of the Peninsula. It is worth the drive to see the whales up close and personal and possibly even pet them from a Panga boat in this pristine Nursery.
One of the most incredible natural wonders on the Baja peninsula is visiting with the Gray whales that come to the warm lagoons of Baja California Sur to breed and give birth every winter. Every October, the Gray whales of the Pacific begin a two-to-three-month migration from the cold Alaskan seas to the warm waters of Baja California. At nearly 14,000 miles round-trip, it is the longest annual migration of any mammal. The Gray whales travel to the warm lagoons of Baja California to mate and give birth to their calves.
