When to visit USA's National Parks
Many make the canyon pilgrimage in summer, when schools are out and the sun is at its fiercest. However, with frosty winters, enjoy temperate climes from March to May and September to November when crowds start thinning out. Placed apart, check individual forecasts for each park. The domed spires of Bryce Canyon, for example, receive a wintery dusting of snow due to their high elevation.
