From the Casey Meadows Trail (343) it is approximately 6 miles to Casey Peak. Once you reach the Casey Peak Trail continue about 1.5 miles. This part of the trail has over a dozen switchbacks. There are fabulous views in all directions from the peak that include Helena, East Helena and the valley to the north, Canyon Ferry Lake to the east, Elkhorn Peak to the south, and the Continental Divide to the west.
For the more ambitious hiker you may want to take the loop that is approximately 14 miles round-trip and an extra 400-foot elevation gain. To take the loop, return from the peak west to the Montgomery Park Trail 301 to the McClellan Creek Trail 302 back to the Casey meadows/McClellan Creek Trailhead.
