From Trail Ridge Road, Upper Main Slope is the most obvious, wide-open slope. This line often holds the best snow in the area, mid-winter, and is the most popular line in Upper Hidden Valley, for good reason.

Trail Ridge Road was open so we parked on the side and skipped the lower T-bar area. Did a few laps, plenty of snow but very wet and sticky 1mi
