Yesterday we hiked the Bierstadt Trail at the Rocky Mountain National Park. It is an about 5 km long loop trail with an elevation gain of 200 meters.
The elevation starts right and at the beginning and is there-and-back. Once you climbed up the 200 meters there is an even loop trail on the plateau around Bierstadt lake.
Here’s a screenshot from AllTrails.
You’ll find the most amazing view.
