Monthly Guide

Best National Parks in April

April opens the window for shoulder-season visits to the big-name parks before summer crowds arrive. Zion, Grand Canyon, and Great Smoky Mountains are warming up with manageable visitor counts. Higher-elevation parks are still thawing — Going-to-the-Sun Road in Glacier won't open for months yet. Wildflowers peak in the desert Southwest.
