The trail offers a mix of surfaces. You'll find a paved asphalt section with views of Black Dog Lake, which connects to other trails. Beyond this, the natural surface, tallgrass trail begins near the back of the soccer fields in Cliff Fen Park. This natural section winds through a wet meadow (a fen) and crosses a working railroad track. Be aware that unpaved sections can be muddy, especially after rain, and the trail may flood seasonally as it lies on the Minnesota River floodplain.
The paved portion of the trail, which is part of the larger Black Dog Lake Trail, is generally considered easy with minimal elevation gain. However, the natural surface sections of the Cliff Fen Trail itself are sometimes described as moderate due to the wetland environment and minimal maintenance. It's accessible for most, but be prepared for potentially muddy conditions on the natural paths.
The trail is located within the Minnesota Valley National Wildlife Refuge, a significant habitat for diverse wildlife. You can expect excellent opportunities for birdwatching, with over 250 bird species (both year-round and migratory) in the refuge. Hikers may also encounter at least 50 mammal species and 30 species of reptiles and amphibians. Keep an eye out for marsh and grassland birds, and listen for frogs calling in the fen.
The trail is open year-round. Spring to fall is ideal for walking, enjoying the diverse flora and fauna. However, the unpaved sections can be muddy after rain and may flood seasonally. In winter, the trail transforms, offering opportunities for snowshoeing, cross-country skiing, and fat tire biking. Each season provides a unique experience.
Yes, the trail is open in winter and is suitable for activities like snowshoeing, cross-country skiing, and fat tire biking. It offers a different perspective of the landscape during the colder months.
You can typically find parking at Cliff Fen Park in Burnsville, Minnesota, which provides direct access to the trailhead. Always check local signage for specific parking regulations.
Information regarding specific dog regulations for the Cliff Fen Trail itself is not explicitly detailed. However, as it's part of the Minnesota Valley National Wildlife Refuge, it's generally advisable to keep dogs on a leash and follow all refuge guidelines to protect wildlife and natural habitats. Always clean up after your pet.
There are no entrance fees required to access the Minnesota Valley National Wildlife Refuge or the Cliff Fen Trail. However, visitors should always respect refuge regulations, which are designed to protect the natural environment and wildlife. You can find more information on the official FWS website.
Yes, the paved section of the trail is part of the larger Black Dog Lake Trail. The route also passes through sections of the Cliff Road Trail and other segments of the Black Dog Trail, offering opportunities to extend your hike.
Given the varied terrain and potential for mud, especially on natural surfaces, we recommend wearing sturdy, waterproof hiking shoes or boots. Dress in layers suitable for the weather, and consider bringing insect repellent, particularly during warmer months when hiking through wetlands.
The natural surface sections of the trail are described as 'minimal maintenance' and run through wetlands. This means they can be quite muddy after rain and are prone to seasonal flooding, as the trail lies on the Minnesota River floodplain. Be prepared for potentially wet conditions and uneven surfaces on these parts of the route.
