Exploring Yosemite Valley by bicycle opens a world of possibilities that aren't afforded by car. In addition to having an endless supply of bike parking (you can pull off just about anywhere), you have the open air freedom to take in the scenery while cruising and can stop on a whim to tour an a magnificent meadow, gaze up at granite monoliths, or warm up in front of a fire at the historic Ahwahnee Hotel.
The heart of the floor of Yosemite Valley, from Bridalveil Meadow in the west to Mirror Lake below Half Dome in the east, is over 7 miles one way connected by roads, bike paths and walking paths. It's a daunting round trip by foot but a cinch on a bike. Views to most of Yosemite Valley's famous granite landmarks fall within this area, as does access to many of the waterfalls, meadows, and the scenic Merced River banks and bridges. Touring by bike makes access to all of this easy and feasible within a portion of a day. Consider side trips to Mirror Lake, The Ahwahnee, Lower Yosemite Falls, Leidig Meadow, Sentinel Bridge, Hanging Bridge, Bridalveil Meadow and El Capitan Meadow. And you are sure to be drawn in elsewhere for worthwhile detours!
The eastern third of the valley is setup to be very biker friendly with a network of bike and walking paths separate from the roads. As you head west, the bike paths end and cyclists share Northside and Southside Drive with automobiles. If you are not already staying in the valley and parked at a campground or lodge/hotel, there is central parking at Yosemite Village, Yosemite Lodge and at the Happy Isles Trail Parking area from which you can begin your bike tour. Many variations of loops exist. Don’t forget to bring a lock to leave your bike for side excursions.
If you didn't bring a bike of your own, not to worry. Bikes can be rented at multiple locations throughout the valley including Curry Village and Yosemite Lodge.
