This colonial-style mansion, with its sparkling white exterior and hunter-green shutters, recalls the grand summer residences more often seen on the East Coast. It is the highest point on the island, and it rests amid beautiful shrubbery and landscaping. Completed in 1921, the former home of chewing gum magnate William Wrigley Jr. hosted important social gatherings during its heyday. Nowadays, you’re the guest of honor in the cozy Inn’s six guest rooms and suites, which feature ocean or harbor views (some rooms have fireplaces and some have terraces or decks). Floral-patterned wallpaper, bed coverings and window treatments lend a New England ambience, while high ceilings and large windows make the rooms feel spacious.

The Inn on Mount Ada Amenities:

• 6 rooms, 1 suite. Children over 14 years only. Complimentary breakfast and lunch.
