Sixty Lakes Basin Trail

Sixty Lakes Basin is a high-country side hike from the Rae Lakes and John Muir Trail corridor. The mapped trail runs 3.13 miles one way from a junction near northern Rae Lake into the basin; the visitor distance here is 6.3 miles round trip, returning on the same route. That figure covers only the basin detour, not the long hike to Rae Lakes from Road’s End or Onion Valley. Plan about 6.5 hours for the side trip itself, with more time if altitude, stops or route-finding slow you down. It is a remote, strenuous choice for a day when you are already in the backcountry.

The side trail leaves the John Muir Trail before its stream crossing between the Rae Lakes, then skirts wet ground near northern Rae Lake. It climbs about 600 feet to a low divide. A small lake lies just below the top, and the view opens back across Rae Lakes toward the Sierra Crest. Pause here and look behind you; the little lake in the foreground and the Rae Lakes beyond make the clearest sense of the climb’s payoff.

On the basin side, the path drops roughly 400 feet over the next half mile, passing smaller lakes. The change is quick: the climb and the divide are behind you, while the basin’s stream and broad valley lead the walk farther in.

Beyond the lakes, the route follows the main stream down a shallow, gently sloping canyon for a little over a mile, ending near a steep drop in the watercourse toward the South Fork Kings River. The lower lakes and stream corridor are on the mapped route. Higher lakes closer to King Spur sit above it and take separate off-trail excursions; they are not included in the 6.3-mile distance. An alternate scramble from Glenn Pass is a different, off-trail approach, not part of this walk.

The way back is the same corridor, so save energy for the climb over the divide on your return. The upper end of the basin route can become faint, making this more demanding than its mileage suggests. Keep the mapped line handy and use the stream valley and lakes as landmarks; turn around at the route’s upper endpoint rather than assuming the trail continues to every lake. The mapped corridor stays above 10,500 feet, where altitude can make a steady climb feel harder.

There is no road access or parking at the start: it is a junction on the John Muir Trail near northern Rae Lake. Reach it on foot through the Rae Lakes backcountry from Road’s End, or by approaching from Onion Valley over Kearsarge Pass. Those long approaches are separate from the distance and time recorded here, so this is not a drive-to day hike.

Pets are not allowed on park trails. An overnight trip requires a wilderness permit, and portable bear-resistant food canisters are required in the Rae Lakes area. Campfires are prohibited above 10,000 feet. Stream crossings along the Rae Lakes approach can become hazardous when water is high; check current park trail conditions before leaving.
