Landmark Gap Trail North

Landmark Gap Trail North is a broad out-and-back from Denali Highway Mile 24.6 to the south end of Landmark Gap Lake. The mapped track measures about 2.55 miles each way, so plan on roughly 5.1 miles round-trip and about 2½ hours with time at the lake. The designated route is also described as about three miles to the lake; that figure is best treated as a rounded northbound distance, since the mapped line is shorter. This is an easy, low-gain walk by Alaska standards, but it takes time: the lake, outlet pools and open mountain gap are the payoff, not a quick roadside view.

The trail leaves the highway at Mile 24.6, about 150 yards east of Rock Creek Bridge. A large stream crossing comes roughly a quarter-mile in. The bottom is rocky and firm, but the route also has marshy spots, so expect wet footing in places. This is a shared, designated corridor with off-highway vehicle use; keep to the track and stay aware of other users. No developed parking capacity or services at the access were confirmed.

Most of the walk follows a broad, hardened track through open tundra and low hills. The tread is rocky and generally dry, with little climbing; the sampled route rises gradually from about 947 to 980 meters over the mapped leg. Small rises along the way give the clearest views across the surrounding country. The route follows the outlet flowing from Landmark Gap Lake, rather than Rock Creek, and the scenery opens gradually as you head north.

In the last half-mile, the track comes alongside the outlet several times. This is where the deeper pools are, and where anglers look for Arctic grayling; lake trout are associated with the lake itself. Much of the shoreline is shallow, so the outlet pools are the more promising fishing stops. The lake’s south end is the turn-around. From one of the low rises, frame the outlet with the lake and mountain gap behind it to show how the water threads through the valley.

The trail crosses a highly sensitive archaeological area within the Tangle Lakes Archaeological District. More than 600 archaeological sites have been documented across the wider district, which preserves evidence of Indigenous subsistence and travel in the region going back thousands of years. That history belongs to the landscape, but no particular artifact or feature on this trail is identified for visitors to inspect. Stay on the designated route and leave rocks, soil and anything you find in place.

This is the north-side route from Mile 24.6. The separate Landmark Gap Trail South begins at Mile 24.7 on the other side of the highway and branches toward different destinations; don’t combine those systems when estimating this walk. The North trail is a gradual, open walk for someone willing to spend a few hours reaching the lake and returning the same way. No toilet, potable water, food service, fee, or pet rule was confirmed for this access, so don’t count on a service stop here.
