Trail Description

The trail begins at the trailhead next to the trail sign. It starts to follow a series of switchbacks along the Bierstadt Moraine, gradually gaining elevation.

As you get higher and higher, the views of Longs Peak to the south, the continental divide to the west, and Sprague Lake to the east become more spectacular. There are multiple opportunities for scenic photography at the ends of each switchback.

After 3/4 of a mile, you reach the top of the Bierstadt moraine hike through a flat section of forests, losing 50-60 feet.

At the first trail junction, you can choose to take a right or continue straight (it connects as a loop).

Hike another .2 miles and reach another junction, following the sign to continue along the trail around the lake. Take a sharp right to follow a short segment of the trail that leads directly to the lake shore.

Continue to follow the signs at each trail junction to follow the trail around the lake, until you come to the first junction you originally came to.

Take a left, following the sign back to the Bierstadt Lake Trailhead, going back the same way you came via the switchbacks.

Looking for a longer hike? You can link this hike with any of the hiking trails from Bear Lake, or return to the Park and Ride lot further down along Bear Lake Road.

Safety Tips

The Rocky Mountains are dangerous: Hikers are injured or killed each year while visiting the National Park. Here are some tips to stay safe while hiking in Rocky Mountain National Park.

  1. Check the weather forecast: The weather can change rapidly in the mountains so always check the forecast before you head out and be prepared for all conditions.
  2. Carry essential gear: This includes a map, compass, first-aid kit, multi-tool, headlamp, matches or lighter, and emergency shelter.
  3. Stay on the trail: To protect the environment and for your own safety, always stay on the designated trail.
  4. Stay hydrated and eat regularly: Mountain air is dry and can dehydrate you quickly, and the physical exertion will require you to refuel with food and water.

  6. Tell someone where you’re going and when you’ll be back: If you get lost or injured, someone knowing your plan can save your life.
  7. Be aware of altitude sickness: Symptoms can include headaches, fatigue, stomach illness, dizziness, and sleep disturbance. If you feel sick, descend to a lower altitude as quickly as possible.
