Confirmed from Niwot Loop Trail Trailhead's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
What runners say about Niwot Loop Trail Trailhead
“Beautiful views and nice walk, saw a deer family and enjoyed watching them graze”
“The Niwot Loop Trail is a great trail to run / walk / bike.”
“However the trail system is not very clearly marked.”
Beautiful and peaceful trail. Plenty of trees. Trail is flat and wide. It’s more of a network of trails than a loop. You can easily make it a longer or shorter hike. However the trail system is not very clearly marked. This is our first time there and we could not find the “loop”. Be aware of bobcats.
Absolutely great trail with a mix of incline and decline, also great views. No shade, so on hot days be prepared. I went with my 2 dogs and father who has bad knees, and we all did great. Will do this trail again!
The Niwot Loop Trail is a great trail to run / walk / bike. This trail is also part of the LoBo Trail between Longmont and Boulder. Make sure you review a map before heading out as there are multiple off shoots that you can take. The loop itself provides spectacular views of the front range and Longs Peak.
Niwot loop is a well maintained local loop with amazing view of Rocky mountain, it is good for running, cycling and walking, it will take about 1 to 1.5 hours for running depending your speed and the actual loop, today I took 71 minutes to finish the smaller loop with 5.
