Great Sun. Morning. Not sure why it's rated hard...very mellow but we only did 1/2 from Gateway parking lot (free right by Brainard Lake entrance). So we went about 5miles out and back. We needed a mellow walk and this was really nice and gentle. Full is all day so definitely picnic and stopping at Peace Memorial Bridge is a good location halfway to do that.

Solid, moderate trail to get to Brainard Lake without driving in via Roosevelt entrance. You can find the trailhead at the free parking lot to the right of the parks entrance. nice mellow hike through pines and aspens. beautiful creek.

This is a trail we always end up at for snowshoeing! It has a lot of snowpack and is dog friendly, an essential for a good trail. Not too many people this day, it was snowing a bit but the conditions were great otherwise. More of a trail, not too much to see through the trees and the trail is a bit hard to navigate the dog friendly parts, but good overall!

I hiked a bit on the segment by Beaver Reservoir this month. There's an extended foot bridge over Beaver creek which is marked "Closed". This seems to be due to some missing/rotted boards and missing hand rail over the deepest part of the creek. It is safer than trying to ford the creek but it's definitely "use at your own risk".

As the description states, mainly used for trail running and mountain biking. This is a very strenuous trail that is not recommended for sight seeing or a nice leisurely family hike. This is a very difficult and extremely rocky trail.
