"Beautiful views at Engineer Pass. Road up was pretty easy and had a little bit of traffic going both directions. It was about 20 degrees difference so make sure to pack a jacket if you plan to stay up there for a bit. Overall though it was worth the trip. Will definitely do it again."
Marc Swan
"Absolutely love this area. Did the full Alpine loop for the 2nd time from Cinnamon pass route. The road from lake Como to the top is pretty steep, one lane and seemed more rocky than 2 years ago, but it is amazing this time of year. Lots of wildflowers and waterfalls."

"Any trial hunting enthusiast will enjoy the ride up the mountain side for this view. Spend some time and take it all in. Our mid summer journey had the temperature at a crisp 55 deg with a light breeze."

📸 📸 Photography
The summit offers incredible panoramic shots of the San Juan Mountains. Look for opportunities to capture the rugged trail, historic mining structures, and the vast alpine scenery. Sunrise and sunset can provide dramatic lighting.
A wide-angle lens is great for capturing the expansive landscapes. A telephoto lens can be useful for distant peaks. Don't forget a sturdy tripod for low-light conditions and a polarizing filter to enhance sky and reduce glare.
The 'golden hours' around sunrise and sunset offer the most dramatic and flattering light for landscape photography. Midday sun can be harsh, but can still yield good results with careful composition.
Keep an eye out for pull-offs that offer unique perspectives of the winding road, the surrounding peaks, and any historical mining structures. The summit itself is a prime location.
Be mindful of the steep drop-offs and uneven terrain when setting up your shots. Always prioritize safety. Also, be aware of other vehicles on the narrow trail and avoid blocking passage.
