For much of the trail's length, there is actually a designated path for hiking and biking that's separate from the ATV road. This non-motorized track is much more pleasant to ride than the road, and has much better views along the lake. Look for the signs that denote non-motorized variations.

What's mapped here is a one-way route to Serenity Falls Hut. This is a beautiful and popular hut for backcountry stays near the Eklutna Glacier (reservations required). Whether using the hut or not, this is the jumping-off point for trekking toward the glacier and other remote destinations. You can bike the trail farther than the hut, but not much farther. The bridge near the hut makes a good turnaround point for a bike ride, or a stash point for continuing on foot.

You can of course go any distance out and back instead of taking the trail to its end. For a short outing, you might ride just to the "5-Mile Bridge"–– a notable bridge over a creek about 5 miles from the start of the trail. Note also that if you don't have a bike, you can rent one right at the trailhead. A local outfitter is often set up there during the summer. In the winter, Eklutna Lake remains accessible, and this trail is loved by fat-tire bikers.
