We are coming out 7/28 to 8/3 first 2 nights staying outside SMNP and then down to Alma or FairPlay area, renting a vacation house for the remainder. Family of 4, teen boys ages 19 & 17. Want to be central ( not too much daytime driving) so we can do: whitewater rafting; ATV rental; a few hours one day on horseback; and a day rental Jeep for back-roading. Are we more centrally located for these activities going to South Park area? Any suggestions?
