Arapahoe Basin Ski Area Difficulty Level

Difficulty Score

←  EasyHard  →
Arapahoe Basin Ski Area is one of the hardest ski areas in the country, with a difficulty score of 75.5. This mountain ranks in the top 10% of most-difficult ski resorts in all of North America, mostly due to the fact that it has 73% of its trails rated as expert-level, and a vertical drop of 2,270 feet.


At Parks & Trips, we've created a proprietary Difficulty Score that attempts to show how difficult a particular ski slope is. We get to this number by combining a number of metrics for each resort and comparing them to its peers. Most of the score is based off the amount of easy-intermediate-expert slopes by acreage and the maximum vertical drop of the overall resort, but also includes a few lesser-used metrics as well.

Our algorithm compares each resort’s metrics with all others in North America, then assigns each a Difficulty Score, which we use to rank them accordingly. Resorts with a lower score are easier to ski than those with a higher one. However, a high score does not mean that the resort does not have any easy slopes, or vice versa. This is just an overall score given to the resort based on all its metrics grouped together.

I love traveling the United States. I hunt down fantastic places to visit in the summer and great slopes to ski down in the winter. The first national park I ever visited was the Smokies, but since then, I've been to dozens. However, my favorite by far has been Zion.
