Tanalian Mountain - 2.5mi Strenuous Scramble

Q: How do I get to Port Alsworth?

Port Alsworth is not connected by road. Access is float plane or water transport only. Arrange with local outfitters or fly into Anchorage and charter a float plane to Port Alsworth.

Q: Do I need special gear?

Q: What's the fitness requirement? Can an average hiker do this?

You need solid fitness. This is a strenuous hike with 3,250 feet of elevation gain over 2.5 miles—much steeper than typical trails. If you're comfortable with consistent, steep elevation gain and scrambling, you can do it. Slow pace and frequent breaks are normal.

Trail Highlights

Panoramic 360-degree views of Lake Clark and surrounding mountain peaks from the 3,900-foot summit.

Insider Tips

• The false summit at Mile 2 will trick you—many bail here. Keep pushing; real views begin after. • Muddy sections stay wet even after rain stops—plan accordingly. • Descend before 3 PM to avoid afternoon clouds obscuring views and weather deteriorating. • Bring energy food—the steep grade burns calories fast.

Best Season to Hike

Summer (June-August)

Hiking Tips

Bring 2L water minimum—steep ascent and high altitude drain fast.

Family Info

Bears in area require children to be accompanied by adults at all times. Steep trail and scrambling terrain not suitable for young or less-experienced children. Kids 10+ with solid fitness and scrambling experience could summit with close supervision.

What Hikers Say

Hikers report this is a lung-buster—the steep 3,250-foot elevation gain over 2.5 miles beats down most legs. Expect muddy, slippery scrambling terrain and fickle Alaska weather. Those who summit say the 360-degree Lake Clark views and tundra experience justify the pain.
