Group trip from Boise with several that want a fancy spa resort and several that want to Mtn. Bike, in mid-October, within a long 1 day drive preferably, or maybe a direct flight. Suggestions, please. Sorrel Ranch in Moab, Red Mountain in St. George, UT? Too late in the year for Park City or Tahoe? Anything in Bend, OR? Enchantment in Sedona or Tuscon, AZ (a little too far to drive, maybe)? If anyone has done this type of combo Spa / mtn biking trip out West, I would love to hear about it. Thank you.
