Longs Peak gets all the attention in Rocky Mountain National Park, but just below its summit you’ll find Mount Lady Washington. This thirteener is one of the trio of peaks that frame Chasm Lake below, in addition to Mount Meeker and Longs Peak. It’s an easier mountain to climb than either of the others, and you can’t beat the views of Chasm Lake from its summit. Hiking Mount Lady Washington includes passing through forests and across alpine terrain before you reach a final scramble up the slopes of the mountain.

Hiking Mount Lady Washington - East Slopes
Your adventure hiking Mount Lady Washington begins at the Longs Peak trailhead. I recommend arriving as early as you can, as this trailhead fills very quickly during summer months. Head out on the well-built Longs Peak Trail through the forest to start. You can fill your water during summer months using a water spigot by the start of the trail.
About a half mile into your hike, you’ll start switchbacking your way up the mountain. Continue hiking, passing the Goblin Forest camping area after another mile or so, eventually reaching a small footbridge to cross a stream. You’ll begin to near tree line here, with incredible views of the plains and Twin Sisters Peak to the east.
Now above treeline, continue along the trail, looking for rock cairns for help navigating if you lose the route. Head towards Chasm Junction, marked by a backcountry toilet and a hitching post for horses. Mount Lady Washington rises above you to the west. Turn right left to visit Chasm Lake, and right if hiking Mount Lady Washington.
Continue for about a quarter-mile before turning left and leaving the trail. In spring and early summer, you may be able to put on crampons and use an ice axe to climb snow patches on the slope here. If it has melted, you will need to scramble and hop across boulders to reach the summit. Carefully pick your route up through this large rocks for the easiest possible path to the top. The slope will steepen slightly before reaching you finally reach the summit.
From the top, enjoy the amazing views of Chasm Lake far below, Longs Peak above, and sheer face of the Diamond cliff face in front of you. If you start early enough, you can continue towards the Keyhole to climb Longs Peak for a very long day. Regardless, be sure you start descending with plenty of time to reach tree line before afternoon thunderstorms become a significant hazard. I hope my route guide was helpful and informative.
