For most people the wilderness is an incredible experience and should not be missed. Of all of the National Parks, this park probably has the most available backcountry sites that are easily accessible. For example, Grand Canyon National Park has many incredible hikes, but access can be difficult due to the elevation changes and heat during the summer months. Yellowstone National Park is a high elevation park that has some mountain peaks but the hikes in this book have an average distance of about 4 miles, so the time to hike to the campsite will be less than 3 hours with breaks and slow travel. Yellowstone National Park is best visited from late spring to early fall. Late spring can be wet and still have the potential for snow due to the elevation. Summer is the best time to visit. Early fall has the advantage of the Indian summer temperatures and animals (especially elk and bison) being in the rutting stage. The sound of bugling elk is an experience not to miss.
