Inside, you’ll find only the essentials — a bed, a table, and a tiny kitchen.
Because of its simplicity, you can bring your own camping gear and create a space and time that’s entirely your own.
Bring your favorite coffee set and brew a cup to start the day.

Or make use of the surrounding trees to hang a hammock or stretch out a tarp —
the space is yours to enjoy freely.
You can make full use of both the cabin and its surroundings, discovering many ways to enjoy your time here.
While you can fully enjoy the charm of the outdoors, there’s no need to worry about setting up a tent or preparing bedding — just relax and feel at ease.
