No, the "Discovery, Lake Mary, and Prairie Loop" is not a single named trail. It refers to a combination of three distinct trails within the Rocky Mountain Arsenal National Wildlife Refuge: the Discovery Trail, the Lake Mary Loop Trail, and the Prairie Trail. Hikers can easily link these individual trails to create a diverse and extended experience.
You can typically park at the Visitor Center of the Rocky Mountain Arsenal National Wildlife Refuge, which is the starting point for the Discovery Trail. From there, you can connect to the other trails.
Generally, there are no entrance fees or permits required to access the trails within the Rocky Mountain Arsenal National Wildlife Refuge. However, it's always a good idea to check the official fws.gov website for any updated regulations before your visit.
Pets are generally not allowed on the trails within the Rocky Mountain Arsenal National Wildlife Refuge, including the Discovery, Lake Mary, and Prairie Loop trails. The main exceptions are service animals and pets on the designated Perimeter Trail. Always check refuge rules before bringing your pet.
These trails are open year-round. Spring and summer offer beautiful wildflowers, while fall brings changing foliage. For the best wildlife viewing opportunities, consider hiking at dawn or dusk, regardless of the season.
The Rocky Mountain Arsenal National Wildlife Refuge is known for its diverse wildlife. Along the Discovery Trail, you might spot endangered black-footed ferrets and bison. The Lake Mary Loop Trail is excellent for observing waterfowl, songbirds, deer, raccoons, and muskrat. On the Prairie Trail, look for mule and white-tailed deer, songbirds, and raptors. Some visitors have even reported moose sightings.
Yes, the individual trails that make up this route—Discovery, Lake Mary Loop, and Prairie Trail—are generally considered easy to moderate with minimal elevation gain, making them suitable for beginners and families. The Lake Mary Loop, in particular, is a popular family hike with accessible boardwalks.
The terrain varies across the three trails. The Discovery Trail is a straightforward path from the Visitor Center. The Lake Mary Loop features long boardwalks and piers over the water, offering scenic views. The Prairie Trail winds through mixed and shortgrass prairies, with some wooded sections providing shade. Most paths are well-maintained and accessible.
Yes, a significant highlight is the Lake View at Rocky Mountain Arsenal National Wildlife Refuge, which you'll encounter on the Lake Mary Loop. This trail also features extensive boardwalks over the lake. The Discovery Trail offers views of the Black-Footed Ferret Exhibit and bison pastures.
Yes, these trails are well-connected within the refuge. The Discovery Trail can link to the Lake Mary Loop Trail by crossing Havana Street. The Prairie Trail and Prairie Switchback Trail also connect with the Lake Mary Loop Trail. Additionally, sections of this route overlap with the Denver Orbital Trail - Segment 18, Denver Orbital Trail - Segment 19, and the Rocky Mountain Greenway Trail, allowing for even longer hiking options.
Given the open nature of the refuge, it's essential to bring sunscreen and plenty of water, as there are no water fountains directly on the trails. Binoculars are highly recommended for wildlife viewing. Sturdy walking shoes are advisable, and dressing in layers is always a good idea for Colorado weather.
To maximize your wildlife viewing opportunities, plan your hike for early morning or late afternoon. Also, consider combining the individual trails—Discovery, Lake Mary Loop, and Prairie—to experience the full diversity of the refuge's ecosystems and create a longer, more varied hiking adventure.
