Flattop Mountain is one of the most popular hikes in Anchorage, Alaska and it's easy to see why. This recognizable landmark offers a 360 degree view of the Chugach Mountains, Cook Inlet, Anchorage, and Alaska Range making it a prime spot to watch the sunset and enjoy Alaska's scenery.

This moderate to difficult climb starts at 2200 feet and gets progressively difficult as you get closer to the top. It will cost $5(cash or card) to park at the Glen Alps Trailhead where you will find a set of well maintained trails accessing different parts of the valley including O'mally Peak.

Flattop Mountain Trail is a climb but there are plenty of places to stop, rest, and enjoy views of Mt. Denali, the Sleeping Lady, and Anchorage as the trail traverses along the mountain. Even if you don't have time to summit it's worth the short drive out of town to catch the view just few hundred yards from the trailhead.

The saddle is a great place to assess your comfort level as the trail near the summit becomes steep, requiring some rock scrambling. The summit is a football field sized area with plenty of places to sit, picnic, or even camp. Camping is allowed 1/2 mile from the trailhead and does not require a fee for groups less than 12. Depending on the time of year, Flattop is also a popular place to view the Northern Lights, ski, and paraglide.

Very nice

Very nice, the beginning of the trail is pretty easy and gets harder as you go. The last part to the very top is basically bouldering. The views are unbelievable and you can see all of anchorage. You don’t have to get all the way to the top for a great view but it was a fun challenge to get up there!

Main trail is lame.

There are better options from this trail head. Little O’Malley is a bit less traveled and has a better climb. Flattop is nice but gets crowded and if you take the main trail it gets sketchy, especially for kids, people with mobility issues. They are working on a new approach on the south side which should improve.

Steep But Full Of Panoramic Views

A challenging hike this wraps around and is mostly exposed views. Usually in the summer you will be hiking with lost of tourists and locals. The last bit is kind of like bouldering, I almost gave up with 5 minutes left- a girl was screaming, a guy was clearly scared, and I was just tired! But so worth getting to the top!
