Half Dome is Yosemite's most recognisable peak — roughly 8,800 feet up, with one curved face and the other dropping away at close to a 90-degree angle. It's the rock that inspired The North Face logo and a lifetime of Ansel Adams photographs. It's also, usually, a 14 to 16-mile round-trip slog to the summit. If that's more mountain than you bargained for, or you've only got a single day in the park, there's a much gentler way to stand beneath it: the Mirror Lake Loop.

The trail starts near Clark's Bridge on Happy Isles Loop Road, close to Lower Pines Campground, and it's easy to reach without a car — shuttle stop 17 drops you right there. From the trailhead, a paved mile-long path leads to Mirror Lake itself, where the flat face of Half Dome rises straight out of the water. On a calm day the peak reflects in the lake, which is how it earned its name.

Swimming is a big part of the appeal here. The lake is one of the more popular dipping spots in the park, and cooling off with Half Dome and Mt. Watkins looming above beats most pool scenes going. The full loop runs about five miles with only around 340 feet of elevation gain, so it's genuinely family-friendly — a rare thing for a hike with this kind of payoff.

One caveat worth planning around: Mirror Lake is seasonal. Fed by Tenaya Creek, it can shrink dramatically or vanish altogether by late summer. That's less of a loss than it sounds — the granite amphitheatre around the dry lakebed is still a stunning place to sit and gawp at the rock — but if the reflections are the whole point, aim for spring or early summer. Just know that the same snowmelt that fills the lake makes Tenaya Creek run fast and forceful in those months. The National Park Service warns hikers not to underestimate even shallow-looking water in this part of the park, so keep kids and cameras well back from the banks.

The beauty of the route is its flexibility. Treat it as a two-mile out-and-back if you want the lake and little else, or commit to the full five-mile loop if you've got an afternoon. Either way, you're getting a postcard view of Yosemite's most famous mountain without touching the cables route or an alpine start.

For travellers, this is one of those rare jackpot hikes: minimal effort, maximum icon, and accessible for anyone who can manage a flat paved path. If you're visiting Yosemite on a tight schedule, slotting this in early — before the shuttle queues build and the swimmers arrive — is a smart move.
