The easiest way to reach Dragon's Back is from Engineer Pass Rd. Engineer Pass Rd is 4 wheel drive road connecting historical towns of Silverton, Ouray and Lake City. The road is open only from June to early fall (about October, or when the first big storm snow hits). The Engineer Pass is a high pass at 12,800 feet and the trail to treach Dragon's back starts at the Lake City's side of the pass. The road is rough and popular with ATVs and jeeps. Expect a lot of traffic during the peak summer months of July and August.
There is a lot of information about driving Engineer Pass road on the web. My own observation: the roughest section of the road is if one drives from Ouray. The road from Silverton to Animas Forks is pretty good and then the section from Animas Forks to the summit of Engineer Pass has some really rough spots: you will NOT be able to make it without a high clearance vehicle with 4 WD. The easiest driving is from Lake City. The whole drive is super scenic with incredible views.
Route
Dragons Back scramble
Dragons Back The hike is not too long and passed below Darley Mountain (easier to climb this one from the opposite (west) side and heads towards 13er Wildhorse Peak. There are often sheep along this hike.
The hike is not too long, about 8.7 miles round trip.
I believe there are always different options to reach the summit. I knew from my previous explorations that it is better to start past the lake and ascend an obvious weakness in the lower cliff. There are a couple different options how to scramble higher up and gradually reach the main ridge. I found scrambling here pleasant and not too hard, but it is exposed. The rock is loose, so double/tripple check each hold. There was a sling to rappel off near the summit, which I don't think is needed.
The summit is incredible, great views. There was a small cairn and plastic bottle summit register. The bottle was cracked the log was hard to read.
