Monthly Guide

Best National Parks in October

October delivers peak fall foliage across the eastern parks — Shenandoah, Great Smoky Mountains, and Acadia are at their most photogenic. Mountain parks see early snow at higher elevations but trails below treeline remain accessible. The desert Southwest cools to comfortable temperatures. Crowds are moderate, making this an ideal shoulder-season month.
