It's hard to leave the beauty of Yosemite Valley, but other sections of the park deserve a look. I took a worthwhile ride over Tioga Road to view the northern section of the park. As you leave the valley, head north on Big Oak Flat Road. Gas up when you get to Crane Flat; fuel stations are scarce in the park and all that up/down mountain driving tends to burn gasoline faster.
Out of Crane Flat, turn right on Tioga Road. On the first part of the ride, you'll be winding through a heavily forested area. (Watch for deer--several bounded in front of my car here.) You'll feel the elevation rise as you head east--the valley floor is at about 4,000 feet while Tioga Pass (highest point on the road) approaches 10,000 feet.
After about 15 miles, the scenery begins to open up. Your first stop should be Olmsted Point. From this vantage, you'll get a backdoor view down Tenaya Canyon of Half Dome and the Quarter Domes. Also, there's some good rock scrambling here. Just over a mile further east, you'll pass lovely Tenaya Lake, which offers two picnic areas. During the summer season, the Park Service provides a shuttle bus from the valley to Tioga Road. If you get off at Tenaya Lake, you can hike back into the valley.
I saved my lunch for a point another seven miles down the road: Lembert Dome. You can eat at the picnic tables here, but I recommend walking just a little ways beyond the parking lot and finding solitude on a slab of granite that overlooks the Tuolumne (TWA-lum-nee) Meadows, one of the prettiest sights in this part of the park. There's a short trail that ascends the dome, however it was closed during my visit due to storm damage.
After lunch, I turned around, heading back west. Just a mile into it, I stopped at the Pothole Dome, which is not so attractive itself, but provides some great rock scrambling opportunities and a dynamite view of the prettier Fairview Dome across the highway.
When you're through scrambling, keep driving west, enjoying a different perspective of the same natural features. When you return to Crane Flat, stop at the parking area for the Tuolumne Grove. Walk a mile down a steep (but paved) hill and behold a grove of one of nature's greatest creations: the mighty sequoia. A short path takes you off the paved road (once the old stagecoach route) into the forest of giants. You'll get to see a tunnel tree, some fallen giants and other magnificent sequoia specimens.
You can complete the entire round-trip drive with stops for lunch, hiking and rock scrambling in about five or six hours. Forests, lakes, wildlife, mountain meadows, granite domes, giant sequoias--what more can you ask for in one day?
