Confirmed from Hartley Nature Center'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.
Large refuge for hiking, cycling, cross-country skiing & fishing, plus nature center with exhibits.
What runners say about Hartley Nature Center
“The trails themselves were all very well maintained, and everyone that I encountered on them were very courteous and happy to be out in nature.”
“An amazingly beautiful place to go out for riding bikes and walk.”
“The trails are well kept, and easy to follow (abundant signs and marked).”
Amazing city park. I have been visiting Duluth for the past 3 years and just now discovered this place. I wish I had visited a lot sooner. So many trails to choose from, so many different nature areas. I visited on a Monday and at 9:30am the parking lot was almost full. So I would suggest visiting early if possible.
Totally worth the hike. Favorite place in Duluth. We saw a quail and it was sure cute and come up to us. The trail that leads you up to the rocks was a great view. The colors were stunning.
Never actually been in the nature center, but I've been all over these trails in the park and I can honestly say that I love this place. I've rarely been to a city park and have felt this removed from the city around me.
The best fat bike riding I have experienced. They do an incredible job of grooming. So much fun. Great trails and great scenery.
