Pass Trail to Engineer Mountain Trail

The most common starting point for this hike is at Coal Bank Pass on Highway 550. You'll begin on the Pass Creek Trail from there. Parking is available at the Engineer Mountain Trailhead, which is easily accessible from the pass.

The best time to hike this trail is typically during the summer months, particularly July and August. This is when the alpine meadows are vibrant with wildflowers like Columbine, Orchids, and Geraniums, and the weather is generally most favorable. Be aware that snow patches can linger on the northern aspects of Engineer Mountain even in mid-summer.

Yes, dogs are generally allowed on trails within the San Juan National Forest. However, it's always best to keep your dog on a leash to protect wildlife and ensure a pleasant experience for all hikers. Please remember to pack out all pet waste.

Generally, there are no specific permits required for day hiking the Pass Trail to Engineer Mountain Trail itself, nor are there entrance fees for accessing the San Juan National Forest for day use. However, always check the official San Juan National Forest website (usda.gov) for any updated regulations or specific area closures before your visit.

The terrain varies significantly. The initial section from Coal Bank Pass ascends through meadows on moderate grades before entering a spruce-fir forest. You'll cross a ridge and navigate moderate switchbacks. After about 2.25 miles, you emerge onto the Engineer Plateau, a vast expanse of meadows. If you continue to the summit of Engineer Mountain, the climb becomes significantly more difficult, involving a steep, technical ascent with loose talus, a narrow ridge, and exposed sections requiring scrambling.

This trail is renowned for its spectacular scenery. You'll get terrific views of Engineer Mountain, known for its distinctive "double cone" shape. Other prominent peaks like Twin Sisters, Jura Knob, and Kendall Peak are visible. You'll traverse high meadows, offering expansive vistas of the surrounding mountain ranges, including the Needle Mountains and Animas Valley. Don't miss the View of Engineer Mountain across the lake and the Alpine meadows below the summit of Engineer Mountain. In July and August, the meadows are filled with vibrant wildflowers. You might also spot a rare "rock glacier" and the unique red, layered base of the mountain.

The overall hike is generally rated as strenuous, especially if you aim for the Engineer Mountain summit. While the initial sections through meadows have moderate grades, the high altitude and significant elevation gain make it challenging. The final push to the summit is particularly difficult and exposed. Therefore, it is generally not recommended for beginners or families with young children, unless you plan to only hike a short, out-and-back portion of the lower trail.

Yes, the route primarily follows the Engineer Mountain Trail and the Pass Trail. It also briefly intersects with the Cascade Creek Trail.

To make the most of the stunning wildflower displays and avoid the hottest part of the day, aim to start your hike early in the morning, especially if you're visiting in July or August. The meadows are particularly beautiful in the morning light, and an early start helps you beat potential afternoon thunderstorms common in the San Juans. Also, be aware that the Komoot difficulty rating of 'moderate' applies more to the initial sections; the full ascent to the Engineer Mountain summit is considerably more strenuous.

The Komoot tour data suggests an average duration of approximately 3 hours and 55 minutes for the 12.7 km (7.9 miles) route as mapped. However, this can vary significantly based on your fitness level, the amount of time spent enjoying viewpoints, and whether you attempt the challenging summit of Engineer Mountain. The full round trip to the summit can take considerably longer, often 5-7 hours or more for experienced hikers.
