I thought I'd resurrect this three year old thread because I think the topic has a lot of value as a Public Service Announcement entering a new ski season. Looking to reconfirm earlier nominations and add new input representing all ski regions of North America. The focus should be on ski areas with notable advanced ski terrain AND consistently lower crowds than many competing resorts, recognizing the terms "great skiing" and "no crowds" are subjective and relative within different regions.
Below I have recapped the earlier suggestions and added a few more of my own. MAYBE ONE WAY TO ORGANIZE THIS THREAD IS TO ADD TO THE LIST AND PASTE THE UPDATED COPY WITH EACH NEW POST. Feel free to add comments or qualifiers about suggestions especially for an obscure or counter-intuitive place or if you want to contest other inputs based on recent firsthand experience.
GREAT SKIING WITH NO CROWDS - A LIST OF NORTH AMERICAN SKI AREAS
Many places in Interior BC have low crowds.
The Aspen areas especially Buttermilk (Tiehack)
Big Sky/Moonlight Basin
Many places in MT have low crowds.
WEEKDAYS - non HOLIDAY and LATE SPRING
Everywhere - many of the finest ski areas in the US including numerous not listed above, particularly in the East, are uncrowded during mid-week, non-holiday periods throughout the season and at all times in late spring assuming a good year when advanced terrain remains open. The exception to the weekday rule might be popular resorts in Colorado, Utah and California during March when many US schools and colleges are on staggered Spring Break resulting in strong visitation throughout the month.
