Try to hike in Yosemite Valley in the summer months and you’ll be met with hundreds of visitors. But go in winter and you’ll have plenty of breathing room.

Just be sure to check conditions and bring the proper equipment, whether that’s microspikes for your shoes or anti-freeze water bottles. We asked Hannah Singleton, a veteran hiking guide with Arizona-based Wildland Trekking, which leads guided hikes in many of our country’s national parks, for her favorite wintertime hikes in national parks.
