The Highlands Ranch Mansion opens for free public hours several days a month, mostly on weekdays. Families can walk through on their own or ask a volunteer docent for a guided historic tour. Both are free, and a guided tour runs about 60 to 90 minutes depending on what the group wants to see.
The Mansion and its historic park tell the story of the ranch that gave the community its name. Lawrence Phipps Jr. bought the Diamond K Ranch in 1937 and renamed it Highlands Ranch, and the Arapahoe Hunt Club was headquartered on the property for part of the 20th century. Today the Mansion is a Highlands Ranch Metro District property.
A note for homeschool families: the Mansion’s site does not mention homeschool groups, but public hours are open to everyone and the daytime weekday schedule suits a homeschool calendar. Reservations are recommended for all tours and required for larger groups. The tours page sets that line at eight people and the October listing says 10, so a co-op of any size should reserve.
