This hike is a must-do for those seeking a picturesque adventure, especially during the peak season when timed-entry reservations are required to manage crowds.

2. Red Rocks Trading Post, Red Rocks Park

This 1.6-mile loop trail offers a unique perspective of the iconic Red Rocks Amphitheatre. The path winds through a landscape of spiky yucca, twisted shrubs, and towering sandstone formations, providing a dramatic backdrop for hikers. Despite the crowds, visitors often spot mule deer, adding to the experience. The trail is accessible from the Trading Post or the Upper South Lot, making it a convenient choice for those exploring the area.

3. Peaks to Plains and Welch Ditch, Clear Creek Canyon Park

Located in Golden, this 2.5-mile lollipop trail is an easy and accessible option for hikers. It features a short segment of the paved Clear Creek Trail and a suspension bridge over Welch Ditch. The trail showcases the rugged beauty of Clear Creek Canyon, with its canyon walls often attracting rock climbers. The lollipop design allows hikers to explore the trail in a circular route, providing a sense of variety and exploration.

4. The Manitou Incline, Pike National Forest

The Manitou Incline is a challenging 4.1-mile loop that gains an impressive 1,978 feet in elevation. This trail is a favorite for those seeking a heart-pounding workout, as it features a steep staircase built on railroad ties from a former cable car track. The Incline is not for the faint-hearted, but those who conquer it are rewarded with breathtaking views. The trail also includes bailout points and the Barr Trail for a safe descent.

5. Saint Mary's Glacier, Arapaho National Forest

This 1.7-mile out-and-back trail is a short but stunning hike that leads to the glistening shores of Saint Mary's Lake. The route gains steady elevation, offering grand views of the surrounding forest and a semi-permanent snowfield. Many hikers take a refreshing dip in the frosty waters, making it a popular spot for cooling off. Early arrival is recommended due to limited parking and a $20 parking fee during peak season.

6. Mount Galbraith Loop via Cedar Gulch, Mount Galbraith Park

The Mount Galbraith Loop is an appealing 4.3-mile lollipop trail with moderate difficulty and expansive views. Hikers follow the narrow Cedar Gulch Trail, then ascend the circuit clockwise, taking in the Golden scenery and the distant Denver skyline. The descent is shaded by pines, providing a welcome contrast to the sunny hike. Be cautious of rattlesnakes during the warm months.

8. Mount Bierstadt, Mount Evans Wilderness

Mount Bierstadt is a challenging 7.3-mile out-and-back trail that attracts hikers seeking their first fourteener. The Class 2 trail demands serious effort, with a wooden boardwalk leading to steep switchbacks and scrambling near the 14,064-foot peak. The panoramic views of the Front Range make the ascent worthwhile, but hikers should plan to start early to secure parking and beat the afternoon storms.

Lost Lake is a popular day trip and backpacking destination, accessible via a 4.2-mile out-and-back trail. The route features several waterfalls, wooden bridges over Boulder Creek, and eight designated campsites around the lake.

This trail is especially popular during peak wildflower season, when the path is lined with rosy paintbrushes and blue and white columbines.
