Sentinel Dome is the lone à la carte item on the otherwise prix fixe list of viewpoints on the Pohono Trail. The trail goes past the base of the dome, but not up it. You'll have to detour about a quarter of a mile and climb 300 feet to take in the trail's lone 360-degree panorama. Is it worth it? If you have to ask, which presumably means you've never been there, the answer is: absolutely, unquestionably, yes. Yes with bells on, wearing a tuxedo and a top hat and a belly button ring and carrying a tray of margaritas. The outlines of Cathedral Rocks and El Capitan visible through the mist in the above photo are just a corner of the wonders visible from here. It's one of the most accessible 360-degree views in the park - ask someone who's been up Mt. Hoffman or Mt. Dana whether they think climbing Sentinel Dome is a hardship.
