Trail Overview

Arrastra Gulch to Little Giant Basin is an exceptional, moderate high-alpine climb just outside of Silverton, Colorado, perfect for four-wheel-drive enthusiasts seeking dramatic mining history and rugged mountain scenery. Spanning approximately 3.8 miles one way, this trail ascends aggressively from an elevation of 9,461 feet to a breathtaking 12,106 feet, serving up over 2,700 feet of elevation gain along the way. Unlike the softer, grassy meadows of the nearby Million Dollar Highway, this route carves through a starker, rockier landscape dominated by towering peaks like Hazelton Mountain and King Solomon Mountain. Along the route, travelers will encounter impressive, well-preserved mining relics, including massive metal tramway towers that stand as testament to the area's rich mining heritage. The trail is highly accessible to standard four-wheel-drive vehicles and SxSs, with a technical rating of 3 due to a few rocky steps and minor obstacles that may require careful tire placement. As the track winds deeper into the gulch, drivers will navigate several narrow shelf road sections where passing is impossible, requiring careful attention to oncoming traffic. While most of the rocky obstacles are located away from steep drop-offs, reducing the overall consequence, utilizing low range can help smooth out the crawl over the larger rock steps. The trail culminates near a scenic high-alpine mountain lake tucked into the basin, where a short extension beyond the water leads to a convenient turnaround point. Beyond this vehicle turnaround, the extremely steep path continuing over the pass is reserved exclusively for hikers, runners, and mountain bikers. The route is typically accessible from late spring through early autumn, depending on seasonal snowpack.

Difficulty

There are a couple of spots where there is a rock or two you have to go up and over. Something with AWD might have issues here depending on how the transfercase is configuring. Anything with 4x4 should be just fine. None of the rocky spots are near a cliff, so consequence is low once you are past the tight spots.

Saw 1 hiker - no other vehicles. The 3 rating does feel misleading due to the steep terrain & 95% of the trail being loose rock. There was some ice after the first blind corner. Beautiful trail with incredible views the whole way! Slow & easy gets you there, well worth it xx

It was a great day for trail riding up. only ran across 2 other SUVs. this trail I would say is a 3.5. you definitely need a 4x4 and with some height clearance. we ran it up and down on 4 low and aired down to 25. it was a great reward at the top.

After the break off at the county road, the first switch back has a small wash out putting you against the rock wall.

This trail was extremely rocky. The trail is 3.8 miles to the top, but for more than 3 miles the trailer is covered in sharp loose rocks. I have a 2024 4Runner and was not able to go more than 3 miles an hour most of the trail. I would recommend at least a small lift kit and bigger than 32 inch tires to do this trail. And the level three difficulty rating is misleading.

I don't have skid plates and believed it necessary to 6-7 times stop to move rocks. maybe it was a 3 last year but i just did both clear lake and kendall mt. road 33 and this was a bit worse than both IMHO😎😎 so it is a 4 + deeper in although starts easy

Pretty nice trail. This time of year I recommend 33in tires and a locking differential to combat the snow
