Baja Expeditions has a number of whale watching and marine mammal experiences available throughout Baja. Don't miss the opportunity to stay at their eco camp in San Ignacio Lagoon, the place where the grey whales go to mate and give birth each winter between December and April before heading back to Alaska. They are a first class outfit with an excellent staff utilizing the spare resouces of the desert wisely. The lagoon is an amazing place for wildlife, not just for whales but also for birds. The Mexican government has established the entire area as the Vizcaino Biosphere Reserve in order to protect it.
