The trail up Tanalian Mountain climbs quickly and steeply up to 3,960 feet. It overlooks Lake Clark National Park and a lot of the surrounding mountains, glaciers, and lakes. This is a tough run that is primarily a power-hike during the uphill. Coming down can be slick but offers a real Alaskan mountain running experience.

The only logical way to get to Lake Clark National Park is via plane or boat. One of the most popular sites for arriving to the park is at Port Alsworth. Only small passenger planes can land here along with boats, so it's best to plan your visit well in advance. That being said, a run in Lake Clark National Park can be an inspiring outing. For more information about flights and boat reservations, visit the NPS website: https://www.nps.gov/lacl/planyourvisit/directions.htm

Kontrashibuna Lake is located within Lake Clark National Park's wilderness area. The trails are more primitive, and so is the nature you will encounter.

Tanalian Falls is a 30-foot waterfall found near Kontrashibuna Lake along the Tanalian River. There are some benches at the overlook area and camping at the end of the Lake Trail. The further past the falls you run, the fewer people you will see.

The beaver pond — and a well-placed bench for taking it in — is a highlight of this relatively tranquil trail. You might even be lucky enough to see wild beavers. Watch for the giant mound of sticks that signals a beaver lodge, and be on the lookout for the beavers themselves both in the water and on land. You can turn back and return on the beaver pond trail or, for a change of pace, return via part of the Tanalian Falls trail — although you'll need to make a detour if you want to see the falls themselves.

The summit of 3,960-foot (1,207 m) Tanalian Mountain is a beautiful — and challenging — destination for a day hike. Please remember that weather changes quickly here; park rangers advise that you should always be prepared with rain gear, even on seemingly clear days. Once you pass the trail junction with the Tanalian Falls trail, you may find yourself wading through an overgrown trail — but don't despair. As you start clearing the treeline, you'll enjoy ever-more-impressive views over the surrounding area.

You can reach Kontrashibuna Lake via an unmaintained, often overgrown extension of the Tanalian Falls trail. The lake itself is a popular backcountry backpacking destination, but it can be a great day hiking destination as well.

One of the few maintained trails in Lake Clark National Park, the trail to Tanalian Falls alternates between a steep gravel roadway and planked boardwalk. Although you can follow this trail to the waterfall its name implies, you can also use it as an access trail for exploring other destinations, including Tanalian Mountain, Kontrashibuna Lake, and a nearby beaver pond.
