Best Boulder Hikes
Courtesy of Steve Lagreca -

Boulder residents and visitors will never get bored when choosing a hiking destination – there are 145 miles of trails and endless options on offer, whether you have just an hour or a whole weekend. Located at the foothills of the Rocky Mountains and surrounded by lush prairies full of grasses and wildflowers, choosing a destination often depends on your fitness level and whether you are bringing a dog. Most trails going west start in the vast Chautauqua Park. Flagstaff Mountain is located at the city's outskirts and offers short but strenuous hikes. Mount Sanitas is another popular destination, also fairly difficult but with views at the top that are worth a bit of scramble.

Arapaho Glacier is located in Roosevelt National Forest, bordering Colorado's North Arapaho Peak. This alpine glacier was once the largest glacier in Colorado but has lost more than half of its surface area over the last century. The trail is very popular and busy. From the Arapaho Glacier trailhead the trail leads to Arapaho Glacier Overlook after 6 miles and to the Fourth of July Mine after 7.8 miles. Two trails intersect the Indian Peaks Wilderness, first through dense forests and then through the open tundra, from where the view of the entire city of Boulder watershed is spectacular. The highest point is South Arapaho, an overlook of the Arapaho Glacier, at 13,397 feet. There is a seasonal campground at Rainbow Lakes, but campfires are not allowed. Dogs are allowed but must be on a leash.

2.Royal Arch Trail

Following the old road from Chautauqua to the Bluebird Shelter for about half a mile, visitors will find the trailhead for the Royal Arch trail, which leads to one of the most popular hiking destinations in the Boulder area. The hike is only about a mile and half long and starts out across a lovely meadow full of wildflowers. Once you enter a pine forest, the trail is steep and fairly strenuous, leading upwards all the way. The rock arch at the top and the fantastic views of Boulder and the Flatirons are well worth it.

At the end of the Table Mesa Road in Boulder starts a trail that will take you to the National Center for Atmospheric Research, or NCAR. From the NCAR trailhead at the center is a short distance to the Mesa Trail and many other trails that branch out in all directions from this major trail. If you go south on the Mesa Trail, take the Bear Canyon trail, which will take you through a narrow canyon with high, almost vertical, walls with a few waterfalls deep below. Once at the top of Bear Canyon, you can choose the Green or Bear Mountain trails, which lead to the summits of these two mountains. Another nice trail leads from the NCAR trailhead to the Mallory Cave, with fantastic views.
