Most people choose to ride uphill on one of the old logging trails or doubletracks. There are a variety of ways back down ranging from easy to advanced in difficulty.
The two downhill-only trails Wildcard and Beginner's Luck drop off the back of the summit and are definitely not lucky for beginners. They're serious downhill trails. They flow very nicely, but have berms, banks, bridges, and drops.
A more mellow route back to town is the I95 trail.
As a general rule, the farther you get from town the harder the trails become. Two exceptions to that are Rhyme & Reason and Tin Can Alley, which, while mostly flat offer a number of technical challenges.
The land has been owned since 1975 by the Caswell family. Dr. Caswell was a physician in town for almost 30 years and was an outdoor enthusiast and often trained local search and rescue teams and ski resort patrol members. Linda's Lookout is named Mrs. Caswell, who often hiked to that spot. The family is actively involved in designing and promoting PRKR MTN and you are likely to see Taylor Caswell out riding the trails.
From Linda's Lookout you can ride downhill singletracks all the way back to town starting with Gardner's Trail.
When you do, a good first stop when you get back to town is the Schilling Beer Company, a riverside brewpub with the best local beer around as well as a great place for lunch or dinner. Other notable places to eat are Miller's Café, Chang Thai, M-Zo Coffee and Tea, Bailiwick's, or Gold House Pizza. And there are many more.
Lodging includes Thayer's Inn, The Beal House Inn and Restaurant, Hampton Inn, and many more.
Littleton's award-winning downtown makes it an excellent choice as basecamp for an epic weekend riding PRKR MTN and Kingdom Trails, located only 40 minutes northwest of Littleton.
