When is the best time of year to hike the Larch Pass - Hidden Lakes Loop?

The usual hiking window is late summer into early fall, when high-country trails in the Pasayten are more likely to be snow-free. Early fall is especially appealing on Larch Pass - Hidden Lakes Loop because the alpine larches turn gold, but conditions can change quickly at higher elevations, so snow, cold nights, and smoke are all possible later in the season.
