3. Glacier National Park
Spanning more than 700lakes and two mountain ranges across Montana, this National Park is perfect for those who love foresty hikes and adventures. The Iceberg Lake Trail and the Trail of the Cedars are among favorites among tourists and locals alike.
There’s also a UNESCO World Heritage nestled within this park, the unique Waterton-Glacier International Peace Park, the union of Waterton Lakes National Park in Canada and Glacier National Park. Before you head there you should know that the parks have different administrations and, thus, separate entrance fees.
Of course, you can also enjoy a scenic ride along the Going-to-the-Sun Road. This is the only road that traverses the park, reaching an elevation of 6,646 feet at its highest.
