Breck or Keystone?

Both are pretty mellow mountains but Breckinridge has more steeps and cliffs by far even though they're all easy stuff

Keystone is completely devoid of anything challenging. Outback bowl can be fun but is not steep in the least. Breckenridge has some more challenging slopes if you know where to find them. We're not talking anything that really compares to other more extreme resorts but they do have some runs that can be entertaining and slightly technical. If you go to breckenridge, try the lake chutes, e chair, whales tail, and windows.

Try A-Basin too the runs are shorter, but steeper and more natural stuff. Still not much is open yet, but on years with a stronger snowfall it is crazy fun.
