A gentle lake walk within the city This is a very easy walk around Harper Lake. The area is a wildlife refuge, so you might see some animals or birds. You can start either way and loop around back to the start.

Nice quick and easy walking/running loop trail around a lake. Flat and not much shade. Measured distance about 0.9 per loop.

Very light and easy trail. Fun for the family and nice for a quiet afternoon walk with light traffic. Birds and geese were seen as well.

Walking path. Sometimes stop when driving back to Boulder. You can see fish jump out of the lake and sometimes birds are prevalent. Calm and peaceful. The loop goes by fast even at a leisurely pace.

Beautiful, easy trail... my only complaint is the gravel path was super bumpy ... aka not stroller friendly! Other than that, gorgeous views and a great walk

Nice little mellow hike that only takes 30 mins or so to walk around the lake. Pretty nice view of the flatirons from there too.
