Colorado Day Hikes: Mayflower Gulch

This might actually be my favorite winter hike of all time. 

My first trip to Mayflower Gulch was with a friend in early 2019; the second visit was just this last weekend with Pat. Mayflower Gulch is a beautiful winter destination. The only downfall is that to get there from Denver one must brave the ski traffic on I-70. And boy does it suck. We were on the interstate by 6:30am and traffic was already building. It should have been about a 90 minute drive to the trailhead, but it took us at least 2 hours to get there and more than 2.5 to get home… both times. I don’t know how people do this every weekend in the winter. Once was enough for me.

Anyway, the Mayflower Gulch trailhead is located along CO Highway 91 about 6 miles (9.6 km) past Copper Mountain ski area. The parking lot isn’t marked, but it’s plowed in the winter and will be visible as you approach. There are no restrooms or water at the trailhead.

The first portion of the trail is a 4WD road in the summer, but in winter it’s only open for skiing and hiking. On both visits, we strapped on our snowshoes and began making our way up the trail into Mayflower Gulch. This area is home to the old – and ultimately unsuccessful – Boston Gold Mine. The first of the ruins are visible along the trail. A photo of one is below; the other was so buried in snow that I didn’t even see it on my first visit and wasn’t able to get a good photo of it the second time around.

After about 2 miles, the trail emerges from the trees and forks; we initially continued to the right and up toward the ridge line but promptly abandoned this attempt as it was headed straight up an avalanche-prone slope.

Retracing our steps, we returned to the intersection and went left this time, past a gate (which was nearly buried in snow) and up into the center of the gulch. This area is home to the rest of the Boston Mine remains and is open for exploration. You can even walk into a couple of the buildings.

From the main area, there is another building up the hillside that’s just barely visible. On my first visit, no one had yet been up there that morning so we decided to break trail up to it and once we did a few others began to follow.

Prior to our visit this past weekend, I’d heard rumors that there were a couple more buildings up even higher. Pat and I took a chance – and it was a pretty big chance, given that we had to break trail through deep snow for quite a distance – but there were in fact two more buildings up there. One of them was the largest structure in the area and from it, a cable extended up the hillside to a second structure that appeared to be built into the side of a cliff.

Truthfully, though, it would’ve been worth the trek even if there hadn’t been ruins, because once we reached this upper bowl we had gained enough elevation to see over the western wall of Mayflower Gulch to the rugged mountains beyond.

And just as we were preparing to forge a path back down, Pat and I glanced over our shoulders to see an example of a phenomenon called cloud iridescence (photo below). These rainbow illusions form when sunlight reflects or refracts off certain types of clouds, and since the sun hadn’t yet crested the ridge we were able to see the full array of colors.

It was an unexpected and colorful ending to a beautiful winter hike!


The Important Stuff:

  • Getting there: the trailhead is located off CO Highway 91 about 6 miles (9.7 km) south of Copper Mountain; coming from Copper Mountain, the parking lot will be on your left
  • Fees and passes: none
  • Hiking: 5 miles (8 km) round trip and 1400 feet (430 m) elevation gain, plus any additional exploring/climbing you want to do once you reach the gulch
  • Where to stay: there are many options for camping and lodging in the area, as you’ll be in the heart of ski country
  • Other: though the trail travels through terrain that’s at fairly low avalanche risk, Mayflower Gulch itself is surrounded by slopes that are at an optimal angle for avalanches. We felt fairly safe, as the gulch is large and wide open and we probably could have moved out of the way of any avalanche that did occur. However, if you’re planning to continue climbing up the slopes you should carry avalanche gear and be mindful of all the hikers down below you.

  1. What I’m taking from this post is that I should visit Colorado in the summer and the winter. Looks like there are endless opportunities for great hiking trails with lovely views of the mountains. This may be a stupid question (but it’s only because there are no mountains in Ontario), but did you have to worry about the risk of an avalanche while hiking along this trail?

    1. Haha yes absolutely, you should visit in both seasons! Summer is beautiful and sunny but the mountains are just so pretty in the winter.

      Not a stupid question at all about the avalanches, it’s something we always check on before heading out. The Gulch itself is pretty wide open so we weren’t terribly concerned, but the walls of the Gulch do have some avalanche potential so we were paying close attention to the snow condition and our surroundings. I wouldn’t have wanted to go any higher than we did.

  2. I can totally see why this might be your favourite winter hike. There is something so appealing about that blanket of white surrounded by mountains and that big sky. I’ve never seen the iridescence you show in your last photo. It’s stunning.

  3. I still haven’t gone in winter…but it looks awesome! Glad you made it all the way up! The ore chute (taller building) is my favorite! The cables were used to bring the ore from the shaft and then it was stored in the ore chute. The other little building up there is a bunkhouse for the workers (since you can still see a mattress frame!), and the first cabins on the trail are the main town area. We think the bigger one may have been a hotel or larger bunkhouse type building. Every time we go we find something new, such a cool spot.

    1. Definitely worth the drive! We’ve never been in summer so I’m sure it looks completely different then. Thanks for the info on the buildings! If there are any signs they’re buried in the winter so I didn’t know any of those details.

  4. Isn’t just Colorado one of the best places on Earth to explore on foot, especially in the winter month? It’s been a while since I’ve seen photos from this corner of the world covered in snow – it looks absolutely amazing. Thanks for sharing and happy trails. Aiva
