Take a hike in the giant sequoia groves: "There are two groves in the northern region. The Merced Grove and the Tuolumne Grove are both along the 120 corridor. Park your vehicle and follow the trails from the parking area. They're great hikes for families and there are benches along the trails. Find a nice quiet spot to enjoy a picnic. But, remember, if you bring food, it's pack it in, pack it out!"
Stop at scenic Olmsted Point: "It provides a great view of Half Dome and is one of the highest vistas inside the park. It's right along Tioga Road, on your way to Tuolumne Meadows. It's a spectacular view of the northern half of Half Dome and a great panoramic view. You're looking at the backside of the dome from how most people see it. Tioga Road closes when the major (winter) storms roll in, so if you don't get up there in the spring or the fall, you'll miss it."
Check out Lembert Dome: "It's a granite rock formation located on the east end of Tuolumne Meadows. Enjoy a picnic at the base of the dome or hike up. The trailhead starts at an elevation of 8,500 feet. You ascend to over 9,000 feet at the summit. It's a short trail — 2.8 miles round trip that takes about one to two hours – but very strenuous. Once you're there, though, it's a spectacular view of Tuolumne Meadows and the entire mountain range of the high country."
