Thuya Garden is a semi-formal herbaceous garden, in the style of Gertrude Jekyll, located at 15 Thuya Drive, Northeast Harbor, Maine. It is open daily from May through October. The garden is located on the grounds of Thuya Lodge, built between 1912 and 1916 for Boston landscape architect Joseph Henry Curtis. At that time, today's garden was an orchard. After Curtis' death in 1928, Thuya Lodge and its grounds were placed in a trust directed by his friend Charles K. Savage, an heir of the nearby Asticou Inn and creator of the Asticou Azalea Garden. Today's greatly expanded garden was originally conceived in 1933 by Savage, and built from 1956 to 1961 with plants from Beatrix Farrand's Reef Point Garden in Bar Harbor when that estate was dismantled in 1956, and with financial help from John D. Rockefeller Jr. It opened to the public in 1962. The garden is laid out as a narrow lawn axis with cross-axes, edged by a rustic pavilion to its north and a shallow reflecting pool to the south. Flower beds contain about half perennials and half annuals, with plantings of rhododendrons and mountain laurels.

The Asticou Inn is an inn in Northeast Harbor, Maine. It was built in 1883. In 1899, it was destroyed by fire and rebuilt over the course of two years. The rear of the building overlooks the Northeast Harbor inlet, which opens out to the Atlantic Ocean. The inn has been owned by the Asti-Kim Corporation since 1965 and, between 2015 and 2019, was managed by the Acadia Corporation. Tim Harrington's Kennebunkport Resort Collection became the current managers of the inn in 2023.There are 48 guest rooms: 31 in the main inn, plus 17 in six adjacent buildings: Cranberry Lodge, Blue Spruce, Bird Bank, and three "Topsiders". The inn closes for the seven months between Columbus Day (late October) and Memorial Day (late May).

The Asticou Azalea Garden in Northeast Harbor, Maine, United States, is a popular visitor attraction. It was created by lifelong resident of the village, Charles Kenneth Savage, in 1956. Much of the initial plant collection originated at Reef Point Estate in nearby Bar Harbor, the summer residence of renowned landscape architect Beatrix Farrand. The collection was moved with the financial assistance of John D. Rockefeller Jr., including the weeping hemlock, just north of the main bridge. Located at the intersection of Route 198 and Route 3 (Peabody Drive), the 2.3 acres (0.93 ha) garden and its pond are open to the public during daylight hours from May 1 to October 31. It features a selection of rhododendrons and azaleas, including the Rhododendron canadense, Maine's native azalea. Styled after a Japanese stroll garden, the fine-gravel paths are raked regularly in a manner that suggests flowing water. There is also a sand garden, where this effect is repeated but with the addition of stones, which are meant to represent islands.Savage was also the owner of the Asticou Inn, which is located on the opposite side of Peabody Drive. Prior to the establishment of the garden, the Savage children and grandchildren had made a treehouse and rope swing in the white pine still standing today. The present-day pond was formerly surrounded by an alder swamp.Group photographs for weddings at the inn are often taken in the Garden.

The lighthouse is now a private aid to navigation and a private residence. The rest of the island has belonged to the Dunbar family since 1884 (or 1886), after it was bought by Harvard professor Charles F. Dunbar.

Raventhorp is a historic summerhouse in Southwest Harbor, Maine. It is prominently situated at the northern tip of Greening Island, which is set at the mouth of Somes Sound, the inlet dividing Mount Desert Island, between the villages of Southwest Harbor and Northeast Harbor. It was designed by the partnership of Fred L. Savage and Milton W. Stratton and built in 1895 for Joseph Gilbert Thorp and Anne Longfellow Thorp. The Shingle style house is an important surviving example of this collaboration, and was listed on the National Register of Historic Places in 1988.

Little Long Pond is a pond in Seal Harbor, Maine, United States, at the southern end of Mount Desert Island. Fed by Jordan Stream, a runoff of Jordan Pond, the pond is separated from Bracy Cove at the Gulf of Maine by a narrow causeway carrying State Route 3. It is officially called Long Pond, but has been given the Little prefix to differentiate it from other Long Ponds in the area. A 2.2 miles (3.5 km) trail circumnavigates the pond, while an offshoot leads to Jordan Pond House. Mostly flat on its eastern side, it rises somewhat from the pond's northern end to around halfway down its western side.Little Long Pond includes 17 acres of meadows, 12 acres of marsh, a bog and nearly 1,000 acres of forest. A boat house stands on the eastern shore of the pond. It is possible it was used to serve the farm of Frank Callahan, which stood near the opposite shore in the 19th and early 20th centuries. It has since been demolished. John D. Rockefeller Jr. purchased the land around the pond for its scenic value, and built in 1914 The Eyrie, a summer house atop the hill immediately to the east of the pond. It was torn down in 1962. The land was privately owned until 2015 when, in celebration of his 100th birthday, David Rockefeller Sr. donated it to the Land & Garden Preserve.There is a parking space either side of the gate and along the northern side of Route 3.
