We walked Hummocks after hearing a talk at the main center ....really helped with knowing what we were looking at. It was a very hot day and we were glad that we had water. I would say this trail was easy but longer than I expected. I am 63 and had no trouble even with a grouchy knee. Enjoy!

Went through this trail today with a 5 and 3 yr old. Our 3 yr old rode in the hiking backpack almost the whole way. Would have been a bit much for her, especially up and down some of the steeper inclines. Our son did amazing and did not complain once! Pretty easy 2 1/2 mile loop that give you... More

A hummock is a steep-sided hill that used to be part of the peak of Mount St. Helens. The hummocks were created in the valley of the North Fork Toutle River where the landslide that followed the volcano eruption deposited portions of the former peak. This hike is fantastically beautiful! It is a 2.4 mile loop trail that meanders up... More

We visited Mt. St. Helens while the road was still closed at the Hummocks until the summer season. We used the Hummocks Trail the connect to Boundary Trail to hike all the way to Johnston Observatory. We'd recommend this experience even when the road is open. Slowly traversing the landscape was a much better way to appreciate the environment &... More

Very easy trail, great for small children. Essentially flat, with an easy turn around spot if the full loop is too long for you. The sites are fairly mediocre. If you have the skill for a more difficult trail, I wouldn't recommend spending your time on this one.

An easy-to-modest walking trail among ponds and young forest (under 31 years since the eruption), affording excellent birding habitats.

Spent a great morning exploring the trails near Mt. St. Helens during the American Volkssporting Association National Convention Walk on Hummocks Trail and at the nearby lake. Breathtaking views of the mountain, and the trails give you and up-close look at the results of the eruption and aftermath 35 years later.

The walk is not difficult. It does make you in awe of the power of the pyroclastic flow. There are other mounds.....not sure if they have anything to do with a prehistoric eruption or earthquake near Rochesterr WA.....called Mima Mounds.

We took this trail because our trip research indicated it was the most family friendly. It was a short (2.5 mile) hike, a little up and down with a few great panoramic viewpoints of the Toutle river. What I found most interesting was walking among the hummocks themselves, after learning how they were created when at the Johnston Ridge observatory.... More

The heart of the mountain piled up! Hummocks=heart Since the 1980 blast, this area has the best bird watching as it has attracted birds from Eastern Washington. Old beaver dam, hike to the Toutle River (though no access), new and dying Alder trees - overall a great hike!
