An amazingly beautiful place to go out for riding bikes and walk. I was out for a walk there with a friend and we both absolutely loved it. I am not surprised this friend of mine has some serious plans to visit this place more often now (has even picked a spot to read books and have coffee every morning) !

Dog friendly with bags provided in case you forgot some! Trails are maintained and well marked. Very pretty area.

Great place to run and bike in the summer and ski in the winter. One of the best parks in the city.

Date of Visit: 10/31/2020 - Beautiful hiking trails! Definitely a lovely place to bring the family.

Great hiking. Lots of easy and challenging trails for kids. Also great for pics!

Great Place to go for a walk, sit on a bench and just enjoy nature.

Great place to go year round. fun family spots and always welcoming.

Hartley is Duluths Central Park. The park is on the northern end of Woodland Ave...After a drive down a winding, narrow, road you pull into a horseshoe parking lot that leads to the nature-ctr bldg. There are picnic tables outside to enjoy a break after a hike. Several trails for hiking or biking. Going up Hartley Rd will lead you past a boardwalk trail to a dilapidated root cellar..unsafe to enter. Great time by the family. At a large pond there is a place to rent canoes...well worth the hike at the park.

It was amazing! Beautiful scenery it has wetlands, forests, ponds, streams,creeks and rocks. It has all the sceneries tied into one.

Always a nice walk. Trails are not 100% smooth, sometimes you need to watch your feet. But we take our parents (mid 70s) around these trails & they do great!

After enjoying the view from Rock Knob, we tried our luck at Hartley Pond. Not much happened in our fishing efforts, but still an enjoyable autumn morning at Hartley.

Well kept and marked trails. Great family hiking.

Great hiking trails, never found any overly challenging trails but very scenic..

Great hiking, biking, and ski trails here. Well groomed with lots of nature to see.

Nice facility groomed trails, plenty to see , animals, birds ,pond, education center.

Absolutely beautiful! Great trails, good parking- there’s always a ton- and the center itself is nice as well. Such a wonderful place & well maintained.

Hartley is a fantastic facility dedicated to helping people, young and old, keep in touch with the beauty of nature.

One of my favorite parks in Duluth, great hiking, running and sightseeing. Best park in the lower 48.

Great place to enjoy the outdoors.

We had a great day hiking and geocaching at Hartley park. Lots of trails to explore and a top notch visitor center!

A great park where you can walk a little if s lot. Easy access to the lake, great for dogs and kids too.

Lovely park. Well-kept trails. Helpful staff!

So many well-kept trails. Beautiful scenery.

One of my favorite places to bring my dog. Today was the first time I brought my mountain bike was alot fun

Trails are kept up very well. Has some pretty good trails for biking on.

Many types of trails: wide flat trail, narrow hilly footpaths, and boardwalk,. Rock knob, picnic area, visitor center, and free parking.

Awesome trail to get into nature in your own backyard

Great trails right in the city of Duluth. The nature center is very kid-focused, but there are often activities for everyone. Rock Knob is a great trail!

This is a great place for a hike. The trails are well kept, and easy to follow (abundant signs and marked). There are many spots with great views too.

My family and I had a great time at the Halloween Nature Walk and party before Halloween. The guides at each marker were fun and engaging, and the party inside the building was a blast. My kids particularly loved the balloon room! Great job putting on a fun and educational party HNC!

We picked this place randomly on Google Maps while vacationing in Duluth, and I am so glad we did! Definitely will go back.

Love Hartley nature area for mountain biking!

Great view friendly people lots of trails

We had a kindergarten birthday party here and the staff was very welcoming and kind. They were also very patient with the kids. Everyone had a great time. I would definitely call Hartley for another kids party.

Nice place for a little hike.

Always beautiful in the fall especially.

There are some beautiful trails for everyone. Biking, hiking, walking and ski and snowshoe trails in the winter. A great interpret center. Great for kids of all ages. If you love being outdoors this place has it all within city limits. Beautiful pond and wetland area. Great lookouts too!

Great place to hike with family. Excellent nature programs and classes

Hidden gem in Duluth, great trails, and great photo opportunities

Great City Park with lots of amenities. They have great winter bike and running trails as well as classic ski trails. In the summer lots of running/hiking/biking trails. They have a pond that has reasonable kid type fishing. They also run day camps, have a preschool and do evening and weekend activities for adults.

Easy to get to with nicely groomed cross country ski trails. Could be improved with more trail marking.

Great trails to toke on.

Awesome night ride on the guardrail loop.

A great nature center and outdoor areas with walking and skiing trails. Family friendly park.

Walked 5.5 miles on the trails. They are awesome.

Hartley Nature Center and the surrounding trails, lake and stream are a gem in the city of Duluth. They have great programs for students of all ages and for those wanting exercise or simple nature experiences.

Nice spot to get out for a hike, rent equipment, or take a class.

Hartley is so beautiful. The staff was friendly and helpful. The trails were groomed so well.

The nature center has lots of great animals (mostly dead but some living) for kids to see. The preschool is phenomenal and the kids spend all day everyday outdoors! There are lots of hiking and mountain biking trails for adults and little boardwalks to hidden ponds and fallen trees for kids to climb. Hartley is a way to get away from it all but still be in the city!

One of my favorite parts. Theres so much to see. Can go several times and not experience all the trails.

Great trails for a walk and biking.

Awesome place. Great MountIn biking trail. Got places where you can rest after a hard day of riding, very scenic so if you arent into mountain biking or the outdoors but want a cool picture for your gram there are many places here

Love coming here with my kids and exploring the area. Really enjoy that some of the schools have filled trips here. Wonderful place to learn about nature as well!

Great all year round park for outdoor activities

I love biking here

A Duluth are gem..dont tell anyone

Nice hike.

I love Hartley! They have a wonderful preschool that is nature based and mostly outdoors year round, a yurt with yoga and art classes, lots of different trails from mountain biking to hiking to xc ski in the winter. Want to get lost in the woods but never leave the city - come to Hartley!

Nice area. Easy trails. Butterfly park. Lovely.

Awesome natural play ground and center. Great hiking trails and great history. The trails are marked and map guides for every fork in the road. Enjoy!

I just got a mountain bike and this is a great place to enjoy a quite ride in the woods.

Explored a bit. Had fun on the trils. Need to explire them more

Love this walk with the grandkids. Get to sit on the dock at the end of the trail... fixed up nicely.

Awesome nature center right in Duluth. Makes you feel like you’re out in the middle of nowhere with all the tall trees and meandering nature trails.

Great park in Duluth. One of the best. Beautiful trails, wildlife, and decent fishing in the pond. Cant say enough about this place.

Has a gorgeous view of the lake from rock knob and super fun biking trails

What a great place to be outside!

This is a fantastic place to walk, hike, ski, and bike. I have seen tons of different types of wildlife. Beautiful year round. Everyone I have met here is super helpful and nice.

Its an awesome place to wander the trails and enjoy the nature in abundance.

Super awesome hiking trails. Highly recommend going to the rock Knob. You get a great view of all of the neature. Only complaint I have is the maps along the trail are kind of confusing to read, but Google Maps does a GREAT job of making out the major trails. Id suggest using that (we all had great phone reception, which was a big plus as well)

Always a great time to walk through here! Trails seem to be well maintained as each time Ive gone theres crews out there working hard.

Walk there regularly. Secluded forest with 1/4 mile from busy road

Nice park

Trails were in great shape!

Great outdoor place really well maintained love that there are activities for all ages.

Lots of nice trails, in a variety of environments.

I love that there are places in the middle of Duluth, like Hartley, where I can get outside and be in the middle of the woods while also still being in the city. Hartley is gorgeous all season round with things to do like hiking, skiing, snowshoeing, and running. The Nature Center has events, camps and provides a place to go inside if need be. I enjoy coming here often and getting away by myself or connecting with friends.

A beautiful walk

Hartley has many great trails, hiking of skiing. Inside the main building there are lots of displays and activities for kids.

I am specifically rating the bike park. The Nature center itself seemed quite nice. At first glimpse, these trails are beautiful, good hard pack dirt and gravel, smooth and easy climbing... But there are almost no hard corners!? There are probably two banks in the whole park... And if youre looking for something just a little bit harder, forget it. The blue square is a green circle and the black diamond is impossible. Go to Lester or Piedmont trails.

A great place for hiking , mountain biking and out door education.

Had a great first visit at Hartley! I went as a teacher/chaperone with the First Graders from South Ridge School. We learned about trees and birds and got to listen to a chickadees heartbeat, live and up close against out ears. Wow!Great educators: they real know how to keep the childrens attention. Thank you!

There is a platform in a wide space, and it is one of the BEST places in Duluth to go star gazing.

Amazing Place, Great trails and a very cool pond.

Awesome nature center, great hiking/ biking trails

Its a nice place to walk!

Best park in Duluth. Not that its too high of a bar

Great area to explore, experiment, and get some healthy exercise for the entire family. The only recommendation I would make is to add some additional signage so you know which direction you should head in when coming out of some of the many trails.

Great hikes with the kids. Well managed education center, great staff, and its all five minutes from the house.

Love Hartley! Great trails and beautiful views. Its completely free and a wonderful spot for a picnic.

This park has a lot of awesome trails and cool views! Definitely an overlooked park in Duluth that’s never that busy!

A great place to spend the day or anytime .

A favorite for our family!

Nature right in the city. Multiple interconnecting trails for hiking, biking, skiing, running, etc. Short and long loops, through marshes and forests, past ponds, beautiful vistas, and connecting different neighborhoods. Parking area and outhouse.

Awesome ski trails

Fantasic views and trails

Hartley Park is a wonderful 660 acre park right in the middle of town. It has ski trails, hiking trails, bike trails, streams and a pond. Hartley Nature Center is located in the park, and has excellent nature programming for kids and adults. Pay attention to the trail maps, otherwise youll be hiking/biking/etc. for quite a while.

Beautiful place to hike or bike. Lots of trails.

Beautiful park

This is a lovely Duluth park with many trails that take you past a river and pond that allows you to bring your own canoe, a few trails bring you to the top of a hill that allows you to look down on the surrounding terrain while also offering a small glimpse of Lake Superior! Overall, this is one of my most favorite parks in Duluth and well worth the visit!
