6. Virgin Islands National Park

St. John, Virgin Islands

More sand, but this time, white sand with turquoise water.

And like Glacier Bay, many visitors to Virgin Islands National Park come on cruise ships. However, here, they can get off the ships and explore the park and the waters. That may be a good thing if you’re one of the passengers, but if you are here to get away from it all, you should plan the timing of your beach visit to avoid the cruise ship rush.

The key to a Virgin Islands adventure is getting in the water with a mask and snorkel. There’s so much underwater — and the water is so clear — you’ve got to give it a go. Whether you bring your own equipment or rent locally, much of this hidden gem will remain hidden without them.

7. Big Bend National Park

Texas

The park is often a winter destination because summers get so hot. Winters can get chilly, however, and many people aren’t prepared for elevation gain in Texas. Layering is appropriate in the cooler times of the year.

Known for its rugged desert landscapes, mountainous terrain, and sheer canyon walls, this less-traveled park isn’t big on parking. Some parking lots can get relatively crowded in peak season.

From hiking up the Chisos Mountains to hiking down in the lower elevations of Santa Elena Canyon along the Rio Grande River, Big Bend offers an outdoor experience that is surprising in its diversity.

The park is home to black bears and mountain lions, and is a great place for birders.
