This popular loop through Boulder's Chautauqua Park tops out at a stunning rock arch framing views of Front Range foothills and the plains.

Chautauqua Park is the crown jewel of Boulder's local trail network and the Royal Arch hike is an ideal sampler for fit (or resilient) first-timers. Starting from the Ranger Cottage, begin hiking up the Chautauqua Trail and turn off onto the Bluebell Mesa Trail before the path disappears into the woods.
About 1.1 miles in, the gradual grade ticks up to not-so-gradual, as the trail begins a two-tiered, 0.7-mile climb up to Royal Arch. Slogging up a series of rock steps, this stretch will leave your lungs hurting on the way up, and then take a toll on your knees on the way down. The view from the top is worth it, though: Royal Arch, a rock edifice perched between drainages, offers various overlooks up and down the Front Range. After backtracking downhill for a bit, the route turns back uphill on a detour that traces one of Chautauqua's signature Flatirons before returning to the Ranger Cottage.

RLA002

Location: 39.9956715, -105.2862887

Turn left @ 3-way junction onto the Bluebell Mesa Trail. Continue hiking around the ridge with fantastic views of Boulder and the plains stretching out to the east.

RLA003

Location: 39.9955708, -105.2842449

Bear right @ Y-junction. The trail to the left can also be used to synch up with the Bluebell Shelter at Waypoint 5.

RLA004

Location: 39.9926118, -105.2876459

Follow the trail as it cuts to the left.

RLA005

Location: 39.991087, -105.2873603

Bluebell Shelter: Restrooms are available at the shelter. From here, continue west on the signed Royal Arch trail (it's about 0.9 mile to the summit from here). Ahead, the trail continues through a mix of deciduous and conifer forest, and winds along 2 wooden boardwalks.

RLA006

Location: 39.9893033, -105.2886263

Continue straight @ 3-way on the Royal Arch Trail. From here, the trail picks up a steep, 0.7-mile climb up rugged boulder steps to Royal Arch. There's a brief respite from this climb at Waypoint 7. The route backtracks here on the return trip and bears left heading towards the 2nd and 3rd Flatirons.

RLA007

Location: 39.9844821, -105.2914868

Take a break from the climb amidst a collection of giant boulders perched over views of the Front Range. From here, the trail continues down a short-but-steep rock scramble, before leveling out and then beginning a steep climb to Royal Arch.

RLA008

Location: 39.9818617, -105.2915579

The hike tops out at a magnificent rock arch, which frames views of the Front Range and surrounding plains. Look back the way you came for another excellent view of the Flatirons. Explore the area a bit to find more astonishing overlooks, but use caution scrambling amongst the rocks. From here, descend back down to Waypoint 6 and bear left at that Y-junction.

RLA009

Location: 39.9895869, -105.2903362

The trail encounters a modest-sized boulder often used by local climbers for bouldering. The route is a bit misleading here: Hug the right side of the boulder, and climb up a series of rock steps to continue.

RLA010

Location: 39.9894903, -105.2905548

Continue straight @ 3-way junction bypassing the access trail to the second Flatiron.

RLA011

Location: 39.991713, -105.289376

Continue straight @ 4-way junction.

RAL012

Location: 39.992779, -105.289259

Continue straight @ 4-way junction on the Chautaqua Trail. From here, continue a leisurely, even-footed descent back to the trailhead and Ranger Cottage.
