Use sunset as your turnaround alarm.
Mill Creek is the canyon where dogs are still welcome, off leash on odd-numbered days and leashed on even ones, and Grandeur is the summit that makes best use of that. The west route leaves Church Fork Picnic Area about three miles up the canyon and follows the creek for the first half mile or so before the real climbing starts. The Forest Service says the trail can be hiked nearly year round, which is unusual at this elevation. Snakes are not uncommon, so watch your step.
Valley-and-canyon views; dogs allowed in Millcreek (odd days off-leash).
3 liters water or hydration pack, hiking boots, layers, headlamp, trail mix and jerky, trekking poles, first-aid kit.
