Access Issue: 2025 Seasonal Raptor Closures - Triple Tier, Boston Peak, Grazing Allotment Crag
Details
From the NFS (2/3/25): Seasonal restrictions to protect nesting birds of prey
FORT COLLINS, Colo. (Feb. 3, 2025) – To protect nesting birds of prey, the Roosevelt National Forest began implementing annual closures in several popular recreation areas within the Canyon Lakes and Boulder Ranger Districts on Feb 1, 2025.
On the Canyon Lakes Ranger District, the closure areas include Triple Tier, south of CO Highway 14; Boston Peak, north of CO Highway 14; Grazing Allotment Crag, northwest of Prairie Divide Road; and Mt. Olympus, southeast of US Highway 34. See the closure map for more details.
The Roosevelt National Forest works closely with partners like Colorado Parks and Wildlife, Boulder Climbing Community and the Northern Colorado Climbers Coalition to monitor nesting progress and inform climbers about the importance of giving raptors space to raise their young.
Federal and state laws prohibit disturbing any nesting bird of prey. Visitors can help protect wildlife by respecting all closures. Signs will be posted at key access points into the closed areas. Additional closure information is available online.

Fort Collins, Colo. (March 7, 2024) – to protect nesting birds of prey, the U.S. Forest Service is implementing annual area closures in several popular recreation areas throughout the Canyon Lakes Ranger District. The closures include Triple Tier, south of CO Highway 14; Boston Peak, north of CO Highway 14; Grazing Allotment Crag, northwest of Prairie Divide Road; and Mt. Olympus, southeast of US Highway 34. See the closure map for more details. Effective through July 31, 2024, the closures protect established raptor territories to ensure the birds remain undisturbed during sensitive breeding and nesting seasons.
The Canyon Lakes Ranger District partners with Colorado Parks & Wildlife and the Northern Colorado Climbers Coalition to monitor nesting progress and to inform climbers about the importance of giving raptors space to raise their young.

Description
Greyrock is a 7613-foot granite peak located northwest of Fort Collins. While this crag is relatively obscure to the climbing community, it is far from obscure to the hiking community. The peak lies along a popular hiking trail (Trail #147), and there is a foot trail that travels along the northeast side of the peak that leads to the summit. The peak itself is reached after about an hour's worth of stiff hiking up the trail from the trailhead adjacent to CO Hwy 14. Greyrock and its satellite crags boast well over 100 routes that climb slabs and cracks ranging from fingers to off-widths. The peak's main attraction is the numerous long, moderate routes that scale its flanks. The South Slabs offer a good variety of bolted slab routes from one to three pitches in length (beware of long runouts over easier terrain), while the Southeast Face contains excellent crack and slab routes up to five pitches long. There is also great climbing on the Northwest Slabs and on the numerous satellite crags to the northeast of the peak. One note of caution: do not be caught on the summit during the usual summer thunderstorms!
Climbing Areas: 'South Slabs' 'Southeast Face' 'Northwest Slabs' 'Granite Breakers' 'Granite Sea' Southeast Face: The Southeast Face is a slabby wall laced with numerous cracks. The face contains the highest concentration of long, multi-pitch crack climbs in the area. There are numerous climbs up to 500 feet in length. To get to the Southeast Face, approach Greyrock along the trail until the trail runs along the base, then scramble up through the trees to the base of the wall. To descend from routes that top out on the summit ridge, take the trail that leads down the northeast corner of the peak to the base. Some routes have rappel anchors, but bring two ropes if you plan any rappels.

Getting There
From Denver, head north on I-25 and take exit 269 west into Fort Collins along CO Hwy 14. Once in Fort Collins, turn right on North College Ave (CO 287) and continue another 10 miles. At the turn for CO 14 head west another 8 1/2 miles to the trailhead. Park on the south side of the highway at the Greyrock National Recreation Trail. The trail crosses a footbridge over the river and then climbs up into a dry, rocky draw. At the fork in the trail, keep right and head up through a large, open meadow. Greyrock is at the far side. Plan at least an hour to reach the base of the peak and about 45 minutes to get back to the parking lot. Bring plenty of water.
Per Richard Vogt: the trail to the area is full of poison ivy.
Fixed Hardware
Over the years, Greyrock has been the source of bolting conflicts. At this time, the Northern Colorado Climbers Coalition (NC3) strongly discourages the placement of additional bolts on existing routes, per community consensus. Any new bolts will be removed promptly and the holes will be patched. For questions regarding route development or hardware replacement, please contact the NC3 at nococlimbers@gmail.com
