July in the United States is the heart of summer. While much of the country experiences sweltering humidity and triple-digit temperatures, July is also the magical window when the high-altitude trails of the Rockies and the rugged landscapes of Alaska finally become accessible.
Whether you’re looking for a “cool-cation” to escape the heat or a historic celebration for America’s 250th Anniversary in 2026, here are the best places to travel this July.
1. Philadelphia, Pennsylvania

July 2026 marks the 250th anniversary of the signing of the Declaration of Independence, and there is no better place to be than where it all began.
- The Draw: Expect once-in-a-generation parades, massive firework displays over the Art Museum, and special exhibits at Independence Hall.
- Pro Tip: Book your hotel at least a year in advance for this specific July, as millions are expected to descend on the city for the festivities.

July is the only month you are virtually guaranteed that the famous Going-to-the-Sun Road will be fully open.
