The actual trail is about 3.5 miles, there are no false paths so it is easy to follow. For a little-used trail in Alaska, it is relatively free from overgrowth. The trees and brush end about 3 miles in and the beautiful tundra valley opens up. The end of the official trail is obvious as the double-track just stops on a hill on the Southwest side of the valley, and it is here where the true fun can begin. There are basically three options to continue:

Option 1, cross the valley and hike the ridge on the far side. It might be best after crossing the valley to head back towards Eklutna to get to the beginning of the ridge as its a steep climb from anywhere in Bold valley up to this ridge. From this ridge one can proceed to Hunter Creek Pass, which I believe is the preferred access to climb Bold Peak, or enjoy tramping through the adjoining valley to the Northeast.

Option 2, wander throughout the valley. From the end of the trail, a path exists to the left and heading down into the valley. This path will eventually end above a small pond, continue as desired. It is possible from deep in the valley to make it up to the ridge to the left or Hunter Creek pass but its steep.

Option 3, climb and hike the ridge to the right. From the end of the trail, a path is easily seen that climbs to the ridge. On a nice day this ridge offers a great view of Eklutna Glacier and the lake. Actually the view is outstanding in any direction. I am not sure of whether this ridge provides a decent access to climbing Bold Peak, it did not look like it would.

In mid July 2008, there was still a lot of snow on Bold Peak, patches in the valley (which provided great easy traversing versus the rocks), and plenty of water in the creek for backpacker or dog needs.

Etc:

Regarding the access from Eklutna parking lot to the trailhead, note the gravel road is unfortunately open to ATVs Sun-Wed. A separate bicycle/pedestrian trail along the lake comes and goes about half the distance. Note to save time and hassle, if on bike or walking, there are two instances which it is better to stay on the road versus taking the trail. Both easy to identify. Stay on the road at the very first signed split (1.1 mile mark), this will avoid a muddy and technically difficult (for bikes, especially if have trailer) part of the trail. A noticeable access to the trail will appear about 1/2 mile later. To save time and distance, also stay on the road at the signed split announcing the public use cabin (yurt?). To do same when heading back to the parking lot, stay on the road at the split next to a bench, and leave the trail where it has a Y where the right fork goes 50 feet to the road (it is the only time the trail has a Y while next to the lake).
