TimberStone Adventures Inc., a treehouse resort and disc golf course in Stoneham, says it is giving away its entire property through a photo contest.

The company says the winner of the contest, which requires one photo and a $99 entry fee, will receive three live-in treehouses, a five-story Castle Tower, an 18-hole disc golf course, private mountaintop, 56 acres bordering the White Mountain National Forest, a Polaris Sportsman Side-by-Side vehicle, $25,000 cash and more.

Here are the details from the company:

— The largest treehouse is custom-built, two stories and 1100-plus square feet. It comes fully equipped with all the amenities and includes a full kitchen, a solid oak spiral staircase, two bathrooms with a jetted tub in the master bath, two private bedrooms, open space upstairs with cathedral ceilings for additional sleeping and a large front deck. It also sleeps eight and has Wi-Fi and DirecTV.

— The mid-size treehouse also comes fully equipped with all the amenities, one bath, a kitchen and a loft. It sleeps four, and has a wrap-around deck, Wi-Fi and DirecTV.

— The smaller treehouse is more primitive and is nestled just off of the disc golf course. It has a loft, 12V lighting, front deck and sleeps four.

— The 18-hole mountain disc golf course has Innova DISCatcher baskets, concrete T-pads, handmade benches throughout the course and ends at the base of the mountain throughout the ledges.

— The five-story castle tower is located at the summit of the mountain. Imagine your own 360-degree breathtaking views of the surrounding lakes and mountains of the White Mountain National Forest. Just a half-mile hike from the tower brings you to picturesque and secluded Virginia Lake in the WMNF. There, you will find a beautiful white sandy beach and be completely surrounded by gorgeous mountain backdrops.

— Other extras include a Polaris Sportsman side-by-side vehicle, Woodland Mills sawmill, large family fire pit, hiking trails, snowmobile trails, ATV trails and close proximity to three major ski resorts.
