Calcite is a quirky, lakeside, cabin named after one of the many minerals that were once quarried at this now peaceful spot. Trevassack Lake is right in the centre of The Lizard Peninsula, making it the perfect base for exploring this incredible Area of Outstanding Natural Beauty (AONB). Tucked away behind the lake, this charming, contemporary home is one of six accessible properties at Trevassack Lake sleeping up to five people, with a king size bed in the large "studio style" open plan living area, and a double bed with single bunk on top in the separate bedroom. With floor to ceiling windows throughout and sliding doors opening out on to the large, enclosed garden, you can enjoy your beautiful surroundings from every room.
