Mammoth Mountain skiing, the snowboarding pipes, the Tamarack Cross Country Ski Center, and the entire town of Mammoth Lakes, CA. make the Sierra Nevadas a great place for active vacationers and visitors who love the winter outdoors. Many sports and recreational activities listed are good all year round like going to Hot Creek for a soak, but it is always a good idea to check with a local official or Ranger to make sure the attraction is open. Be careful when venturing outside or into the forest. Be prepared, and be prepared to have fun!
