What to pack

What September feels like

The aspens at Lockett Meadow and up in the Inner Basin turn toward the end of the month and the road in becomes a slow procession, so go early on a weekday. Storms taper off, days stay warm, and the mornings are cold enough that you hold the coffee cup as much for the heat as the coffee.

Expect about 4 days with real rain — enough to notice, not enough to plan around.
