Area D sits perched on a high bench within the Chicago Lakes Basin, offering climbers a unique blend of alpine wilderness and approachable bouldering challenges. Although it hosts only a handful of classic problems, each climb here rewards with a sense of solitude and sharp mountain air that invigorates both mind and body. At nearly 11,800 feet elevation, expect brisk temperatures and fresh, pine-scented breezes that cool your skin as you plan your ascent.

Getting here means parking near Summit Lake, where Denver Mountain Parks manages the lot—reservations are required if you’re parking there, but free roadside spots may be available a short walk away. The approach trail follows a well-worn path that descends about 1,000 feet over roughly a mile, taking you along the Upper Chicago Lakes Trail. This route begins gently with sandy stretches that open into a lush alpine meadow before moving to a willow grove where the boulders come into view on the right side. Although the descent is welcoming, save some energy for the return hike, which is steep and demanding. A cold Gatorade or your favorite electrolyte drink stashed in the car can make the climb out feel a little less daunting.

The climbing here is straightforward but rewarding. On solid granite, the boulders invite you to test your technique on classic problems like Equitas (V7), Nothing, The (V8), and Slander (V9), which range from challenging to demanding. These routes have earned solid reputations for quality and style, each offering a balanced combination of power and finesse. While the number of problems isn’t overwhelming, the vibe here is relaxed yet focused, perfect for climbers who appreciate quieter alpine settings over crowd-heavy venues.

Respect for the wilderness is paramount. Area D lies within the Mt Blue Sky Wilderness Area (formerly Mount Evans), protected and patrolled by the USFS. Climbers must tread lightly to protect this fragile environment—vegetation here can take decades to recover if disturbed. Use crash pads carefully and avoid creating new trails or excessive brushing. Chalk use should be minimal and confined so as not to blemish the natural rock or distract hikers on the trail. Noise pollution, from loud music or shouting, disturbs both wildlife and other visitors. Dogs must remain leashed to protect local fauna.

The climbing season here follows the Colorado mountain calendar, with summer through early fall offering the best conditions. Spring and late fall can bring unpredictable weather, so pack layers and check forecasts before heading out. Note that Mt Blue Sky Road will be closed for the 2025 season, meaning all access is on foot.

While the climbing is limited to three main boulders, the area provides a refreshing alpine escape for those who prioritize quality over quantity. After your climbs, pause to take in panoramic views of the basin, dotted with shimmering alpine lakes and backed by rugged peaks. The combination of steep approaches, brilliant rock, and respectful wilderness rules cultivates a climbing experience that is both grounded and exhilarating.

Whether you’re aiming to send one of the classic problems like Nothing, The or simply to soak in high-country solitude, Area D offers a compelling destination. Its elevated perch in the Chicago Lakes Basin delivers adventure just short of the bustle, ideal for climbers seeking a brief but memorable alpine bouldering outing.
