Best Time to Visit Denver: Shoulder Season Guide
Denver is the gateway to the Rockies — a city at 1,600m elevation that serves as the base for some of North America's finest mountain scenery, skiing, and hiking, while also having a thriving food, beer, and arts scene of its own.
April–May and September–October are Denver's shoulder season windows — the ski season has ended or not yet begun, hiking conditions in the surrounding mountains are excellent, and hotel prices are well below the ski-season peak. The Great American Beer Festival in October is a highlight.
