    Backpack to Odessa Lake via Fern Lake Trailhead

    4.0
    9.65 mi / 1890 ft gain
    Odessa Lake seems to be one of the true hidden gems of Rocky Mountain National Park. Don't get me wrong, you will likely see some folks there, but it is a far cry from the other crowded Bear Lake trailhead lakes. There are two ways to reach Odessa; one, from the Bear Lake Trailhead, and the oth...

    Hike the Resthouse/Lincoln Lake Trail

    4.5
    While the Mt. Evans Wilderness never has a shortage of visitors, thanks to its proximity to Denver, it is possible to find a more private hike if you know where to look. Lincoln Lake Trail, accessible from Echo Lake year-round, is not as glamorous as its sister trail, Chicago Lakes, but is a wond...

    From the parking lot, you can take the Meadowlark trail to the west or the Plymouth Creek Trail to the southeast. It does not matter which trail you take because it ends up becoming loop. For a more gradual slope up the hill, take the Meadowlark trail. After a little more than a mile, it intersec...

    Hike the 7:30 Mine Road in Silver Plume

    4.0
    5 mi / 1200 ft gain
    With a name like 7:30 Mine Road, this is one hike I had to investigate to see if it lives up to its name. Even though this is an easier hike than I normally choose, what it lacks in challenging terrain, it makes up for in historic interest. The view isn’t too bad, either.7:30 Mine Road is about t...
