Yellowstone offers you hundreds of miles of trails. For some of us lazier folks who don't want to spend weeks in the backcountry, a great goal is to visit a few of the beautiful lakes that are only a pleasant walk away from a road.
A short but rather steep hike on a trail lavishly lined with wildflowers can bring you to Trout Lake (left). Its trailhead is about eleven miles from the Northeast Entrance. Trout Lake has always been reputed to be full of large but hard to catch trout. In fact, in the early 20th century it was a source of fish eggs, which were shipped to hatcheries nationwide. If you're there in June or early July, you might get to see the trout spawning in the inlet (to the right as you approach the lake from the trail).
Harlequin Lake is at the end of another short but not so steep trail near Madison Junction. Beaver have built a lodge at one end, and lily pads abound . . .Read more and see the pictures
Mountain lovers and back-country hikers would do well to choose the South Entrance. The entire southern section of the park is remote mountain country of undeveloped high meadow and forest.
"For anyone visiting especially for the first time, I think this book is invaluable. It not only highlights the must-see areas, but details almost every conceivable drive in the park pointing out what to look for, where to stop."
