    What's special

    White sand beachHidden covesRugged shorelineWinding footpathsPrivate island
    Dreaming of owning your very own island in Maine? Welcome to Poplar Knoll--a 31-acre private island where adventure, solitude, and possibility converge. Rising from the waters of Graham Lake near Ellsworth, this remarkable property boasts over 5,700 feet of shoreline, offering an entire world of your own to explore. At the island's heart, a 50-foot rise reveals sweeping views through ancient oak and hemlock forests, while hidden coves, rugged shoreline, and winding footpaths invite endless discovery. The existing improvements--a rustic 20' x 24' camp with loft bedroom, an 8' x 12' bunkhouse, and an 8' x 12' outhouse--provide a simple basecamp for your island adventures or the foundation for a grander vision. A white sand beach stretches out in front of the camp, creating the perfect setting for swimming, boating, and evenings spent around a crackling campfire beneath a canopy of stars. Whether you envision a secluded seasonal retreat, a multi-generational family compound, or a lasting conservation legacy, Poplar Knoll offers a once-in-a-lifetime opportunity to create something truly extraordinary. Complete with a 1/10 ownership share of a mainland access lot on Graham Lake's western shore in Waltham, this rare offering combines the magic of being completely removed from the everyday with the practicality of convenient mainland access. A private island. A blank canvas. A life less ordinary.
