East Side Sierra Shuttle offers specialty transportation services for the Eastern Sierras, such as town to trailhead, airport to trailhead, trailhead to trailhead, vice versa, etc. This is a vital service for mountain-loving adventurers. I used East Side Sierra Shuttle to shuttle me from Whitney Portal to Onion Valley. The service was prompt, professional, and literally as good as it gets. I owe them a great deal of thanks for helping to make my Sierra adventure a success.
