Nature and Parks in Denver

"This one’s for the wildlife lovers. While you’re likely to spot deer, bison, and elk if you head into the hills — you’re all but guaranteed to see them at the Wildlife Loop at Rocky Mountain Arsenal. You’ll also see hawks, coyotes, and more, and it’s a mere 11-mile drive from downtown. Ten miles of hiking trails also beckon anyone who wants to get out of the car and explore further." - MATADOR_NETWORK

Rocky Mountain Arsenal was pure magic! We spotted a whole herd of buffalo, a couple of majestic eagles soaring overhead, and even a young buck casually hanging out like it was no big deal. It felt like stepping into a nature documentary—except we were in it! The drive-through loop was super easy to navigate, and every turn had a new surprise waiting. Such a peaceful, wild gem right outside the city. If you’re craving a little adventure without having to hike miles, this place is a must. Will definitely be back for more wildlife wonders!

What a beautiful place! The lake was calm, wildflowers were everywhere, and I saw prairie dogs, deer, and birds. Peaceful trails and great views so close to Denver. Perfect for a quiet nature walk

Nice, clean park with a surprising amount of “no dogs” signs on the trails. Managed to find a path with no such restrictions and a nice jaunt with the fuzzy bear. Saw a young deer, birds and an Elvira girl who stated she did not like dogs. I said ok that’s cool that’s your prerogative. She starts making a scene- thinking I said “that’s your problem.” I tried to deescalate but I don’t think she knew what the word prerogative means. Her “man” asked me not to speak to her because I was confusing her. I pretty much would expect a person who doesn’t like dogs to be a p.o.s., not a total basket case. Takes all kinds I guess.

This is my favorite place to drive around. It is an 11 mile loop. There are bison, prairie dogs, birds of all kinds, and coyotes, and this past Saturday, I saw a burrowing owl. The skies out there are absolutely beautiful!

I can't express the depth of my love for this place! The wildlife drive is beautiful, the hikes are easy and refreshing, and the information center is intresting and insightful. This is such a fun place to come to to see wildlife thriving in their natural environment! The prairie restoration efforts bring me so much joy and hope for keeping Colorados wildlife safe and healthy, especially in such a dire climate crisis. This is a great place for kids and adults to enjoy nature

A piece of history in the middle of urban sprawl. This is a free access area. You can drive through the entire park. There is fishing allowed in multiple lakes. This requires a fishing permit/license. I saw a few "honest john" boxes for that. There is a visitor center with the history of the park. Get the kids near the window! Buffalo "bison" roam throughout the park. They are in big herds. Don't get out of your vehicle. Once you get to a certain point the road is one way and is about 5+ miles around the park. This allows you to pull over and take pictures from your window. Hundreds of animals roaming, including white tail deer, mule deer, buffalo, all sorts of birds and saw some burrowing owls. There is a free archery range just past the visitor center that looks well maintained. Bicycle and walking paths in parts of the beginning section with convenient benches. Once you turn onto the one way road it feels like you are transported back in time when the buffalo roamed everywhere. A hidden gem. Nice place to bring visiting friends and family.

I enjoyed watching the bison with their babies and the prairie dogs are so cute with their noises. We saw so many different birds including a couple of Snow Egrets! I could stay their all day and watch the wildlife. I gave them a four star as I was taken aback when I entered the Visitor Center and one of the first things I saw was pictures of Trump and Vance! This is no place for politics. Because of this I didn’t stay and buy anything although that was my intention. Otherwise, I love the rest of the place! We also saw one of the ferrets who are nocturnal creatures! I highly recommend if you love wildlife!

We have been through the driving portion, three times on different days, and at different times of the day (morning, afternoon, and right before they close) and we never saw a bison. There were plenty of cute prairie dogs and different species of birds though. We were able to see 2 mule deer on the evening drive, but no white tailed deer and, like I said, no bison. I can't understand, how a herd of 250, fifteen hundred pound animals, can hide so well.
