Summer Lessons

Take advantage of amazing outdoor adventures in Mammoth Lakes and the Eastern Sierra. We offer daily lessons in a variety of sports along with specific camps during the summer.

Summer reservations open on June 1 for lessons starting July 5. This summer season may be a bit different because the snow is still melting from our record breaking year. We plan to offer all of our usual summer activities beginning on July 5th as conditions allow, and will stay flexible as areas and activities become available.

Wednesday – Monday (Closed Tuesdays)

8am – 4pm
