Tips from the Community

June 19, 2025, Davis Reservoirs (Twin Lakes)

Known as Davis Reservoir 1 and 2, these lakes provide a wonderful backdrop for exploring the Gunbarral area. Crushed gravel makes for an easy walk, and off-leash dogs are allowed.

Depending on which direction you're riding you may just be starting your ride, or just about to finish. Either way this bench makes a good spot to have a quick rest or gear check, before taking in the view and then continuing on your way.

You'll get great views from the top of this hill, but the trail to get there is rocky singletrack β€” so watch your ankles and/or consider slowing to a walk where you need to.

The wetland ecosystem found at Walden Ponds Wildlife Habitat was actually the site of industrial gravel pits not too long ago. The county worked hard to turn this riparian environment back into what it once was.

The Sawhill Ponds Wildlife Preserve offers access to a dozen pools of water, walking trails, picnic areas, restrooms, and plentiful parking. This is a great place to find a sense of nature without getting too far from the city.

The Flat Irons are a famous set of "mountains" reaching up the foothills of Boulder. Their jutting, rocky flanks are easy to spot from a pretty far away. From the eastern banks of Davis Reservoir Number 2, you will get a great view of the Flat Irons rising up behind the city.

Frequently Asked Questions

Are there many easy, beginner-friendly hikes in Gunbarrel?

Yes, Gunbarrel is particularly well-suited for beginners and casual walkers. The landscape is dominated by flat, easy-going trails around lakes and across open grasslands. Over half of the trails in the area are rated as easy. A great example is the Coot Lake loop, a very gentle 1.3-mile (2.0 km) path that's perfect for a short, scenic walk.

What are the best trails for seeing mountain views?

Many trails in Gunbarrel offer fantastic, unobstructed views of the Front Range and the Flatirons. The area's open grasslands mean you don't have to climb high for a great panorama. The East Boulder - Gunbarrel Trail, in particular, is celebrated for its expansive perspectives over the plains towards the mountains.

Are dogs allowed on the hiking trails?

Dogs are welcome on many trails, but there are important exceptions. The Twin Lakes Open Space is very popular with dog owners and even has a designated off-leash area for swimming. However, some areas are more sensitive. For example, dogs are not permitted in the White Rocks Nature Preserve to protect its unique wildlife and habitat.

Can I find any waterfall hikes near Gunbarrel?

Yes, you can. The White Rocks Nature Preserve features limestone cliffs and cascading waterfalls. To see them, you can follow the East Boulder Trail to the White Rocks section. Keep in mind that access is restricted to the trail itself to protect the sensitive environment.

What are some good family-friendly or kid-friendly hikes?

The trails around Gunbarrel's lakes are ideal for outings with children. The Twin Lakes loop is a flat and short 1.4-mile (2.2 km) walk that is perfect for all ages. Nearby, Tom Watson Park, adjacent to Coot Lake, also offers a playground and picnic areas, making it a great spot for a family day out.

What kind of wildlife can I expect to see?

Gunbarrel's restored prairie ecosystems and pond habitats are teeming with wildlife. The area is a prime bird-watching destination where you can spot ospreys, great horned owls, bald eagles, and various songbirds. Near prairie dog colonies, it's common to see hawks and eagles. The Walden Ponds and Sawhill Ponds are particularly rich in diverse fauna.

Are there good circular walks or loop trails?

Absolutely. Many of the most popular routes in Gunbarrel are loops, which makes for convenient and varied hiking. The Walden Ponds and Sawhill Ponds loop is a favorite, offering a 3.5-mile (5.6 km) circuit through a beautiful wildlife habitat.

What should I know before visiting the White Rocks Nature Preserve?

White Rocks is a special Habitat Conservation Area with strict rules to protect its sensitive environment. Access is limited to the designated trail only, and you must stay on the path. To protect the wildlife, dogs, bicycles, and horses are not permitted within the preserve. It's a unique area for quiet observation of nature.

What is the best time of year to hike in Gunbarrel?

Spring and fall are generally the most pleasant times to hike, with mild temperatures and beautiful colors. Summer is also popular, but be aware that many trails are in open grasslands with little shade, so it's best to go early in the morning and bring plenty of water. Winter hiking is possible, but trails can be icy or snow-covered.
