Equipment: La Sportiva Trango Tech GTX Hiking Boots, Black Diamond Alpon Carbon Cork Trekking Poles, Osprey Talon 33 Backpack, Kahtoola MICROspikes
Terrain: Dirt and rock trail to Herman Lake. Dirt trail up towards the top of Citadel, and then a rock scramble and climb.
Experience: Herman Gulch Trail is extremely busy every weekend for a good reason. The trek to the lake is flanked by 12ers with incredible views in all directions by the time you reach the water retreat. It's a challenging, hard level 1 route until Herman Lake (not technical), and then the real fun (and views) begin. The top section of the Citadel is classified as Class 3 plus. It requires sure-footing on scree in sections. Still worth it even if you don't finish the last 60 feet nearly straight up (80% grade). Incredible views and a new favorite! Last note: The Citadel All-Trails route offers an alternative route to the Herman Gulch path (the typical route to the lake). Please note that it is NOT a trail past the creek crossing. There isn't a trail to be seen until you reach the initial ascent to Citadel. You are essentially trampling on fields of beautiful wildflowers. Please use this as a guide only during the winter while skiing. And then you can worry about avalanche danger instead......
Personal Trainer Notes: Personal training clients will be challenged by the 1700 feet of elevation gain to the lake alone. Undoubtedly, a good baseline of cardiovascular endurance is required. For the ambitious altitude climbers, you’ll enjoy the remainder of the trail beyond Herman Lake in solitude. The grade of the trail is a workout and requires patience, as well as possibly some butt-scooting on specific sections (if needed). The final climb up is too technical for you, but you can avoid it and enjoy the views at 13,001 feet instead. No judgment here!
