Vail, Colo., Jackson Hole, Wyo., and Park City, Utah, may all be mainstay skiing destinations, but trips to their resorts — or those in any other ski spot in the United States for that matter — shouldn’t be confined to ski season. Pamela Lenci, general manager of Caldera House, a new hotel in Jackson Hole, said that top ski locales offer plenty of diversions in the summer and fall, too.

“You can have just as much fun without hitting the slopes,” she said. Here are some of her best tips to enjoy those ski destinations when the slopes aren’t covered in snow.

Hit the Slopes — by Hiking

Ski resorts are a hiker’s haven, according to Ms. Lenci, with dozens of possible treks ranging from easy to strenuous. The slopes that are so much fun when covered in snow are great to explore when the ground is bare, and many resorts even offer hiking tours off-season. Your hotel’s concierge or the local tourist office will be able to give you a list, along with maps, of all of your options.

And there’s beautiful scenery in store for those willing to hit the trail: “You’ll walk through an abundance of colorful wildflowers,” Ms. Lenci said. “They’re a stunning sight.” While you’re up in the hills, she recommended enjoying lunch at a mountain restaurant and then saving your knees by taking a gondola or tram back down, a perk that many ski resorts offer to hikers in the spring and summer.
