Sentinel Dome is a short hike with excellent bird's eye views of El Capitan, Half Dome, and the entire Yosemite Valley.
One of the most popular places in Yosemite for sunset is Glacier Point, but by walking one mile from the trailhead, the crowds quickly dissipate. Sentinel Dome is great for all ages since the trail is short and not too steep. Park at the Sentinel Dome trailhead, about 3 miles from the end of Glacier Point Road. The trail is one mile, one-way. For the best timing, leave the trailhead at least one hour before sunset.
There's no camping allowed at Sentinel Dome or anywhere within 4 miles of Glacier Point. The one exception is during winter when Glacier Point Rd is unplowed, which converts it to a trail, and the "no camping zone" collapses a bit. A wilderness permit is required year-round for any wilderness area, including Sentinel Dome in winter. Learn more about winter backpacking to Sentinel Dome here: https://www.theoutbound.com/yo... Other than that, enjoy Sentinel for sunrise or sunset, just don't sleep there.
