I will be in Yosemite for 3 nights. The valley is booked so I am planning to stay in Mariposa. When I GPS to Lake Tahoe from Mariposa it shows over a 4 hour drive to Lake Tahoe. When I gps from Yosemite Valley it shows 2 hours. Is there a halfway point to Lake Tahoe I could stay on the 3rd night....Yosemite has me going 395 N into Nevada to lake Tahoe. Mariposa has me going 99N. What's the best route to get to Lake Tahoe?
