From Yosemite, take Highway 140 west out of Yosemite Valley. Mariposa is about an hour's drive away.
From the west take Highway 140 east out of the California's Central Valley. Highway 140 crosses both Interstate 5 and State Route 99, which are the main north-south routes within the valley.
Mariposa is a great place to stay if you are interested in exploring the Merced River. In summer the Merced River is a great place to swim as well as go white water rafting. The American River Recreation, ARTA River Trips, OARS, Whitewater Excitement, and Zephyr Whitewater are several white water rafting companies in Mariposa. They will provide you with everything you need for a great river adventure. Just make sure you call ahead of time to see if the water levels are good for this activity.
