Parking
Start at Granite Creek Campground, where the Isberg Trail begins; Forest Service directions place parking before or after the bridge. Isberg Pass is 11.9 miles up the trail, so there is no vehicle access at the mapped route start.

Post Peak Pass Trail is a 1.45-mile, point-to-point high-country route from Isberg Pass to Post Peak Pass. It crosses a rocky ridge and glacial basin for broad Sierra views. Allow about two hours for this segment. Published descriptions differ: one gives 1.1 miles, while the connected mapped tread measures about 1.45. Plan for roughly 1.5 miles and check a current map before setting out.
Expect granite boulders and loose scree, with switchbacks and minor scrambling and route-finding. A recent account describes the south-side tread shifted onto bare granite beside a meadow drainage; the tread can be faint through meadow and creek terrain. The route sits above 10,000 feet, which makes the short distance feel more demanding.
The payoff is a wide high-country view across the Sierra. The pass is the route’s endpoint; it is not the summit of Post Peak. The rocky ridge and a tarn near the pass make a distinctive landscape view, with granite foreground giving the scene scale.
