Beneath its inky depths lurks a hidden city, the devil or perhaps most chillingly - a bottomless pit. All according to local legend, of course.
Even its name, Lake Gormire, has a mythical, magical ring to it, conjuring up images of the future past scenery of Lord of the Rings or The Hobbit.
Its real life mystery is that it's one of only two natural lakes in Yorkshire, created by meltwater at the end of the last ice age. Added to this curiosity is that no water flows into or from it so it remains incredibly still. The theory is that it's fed by an underground spring and drained through a channel below.
It was vet-turned-author James Herriot who declared the view as the finest in the country.
The viewing platform points out various landmarks - the spectacular views across the Vale of Mowbray, gliders from the Yorkshire Gliding Club, Roulston Scar, Hood Hill, Menwith Hill, Blubberhouses, Garbutt Wood and Lake Gormire below.
Further along the Cleveland Way, you take a left turn down a very, and I mean, very steep footpath that cuts through the woodland. On our recent visit it was just Mr B and myself navigating our way down the slope - kids will need a helping hand and it's a no-go for pushchairs.
However, it's well worth the hike - the lakeside is one of the most tranquil places I have ever been to with a fantasy fairytale atmosphere.
Somebody had already been busy here as there were a couple of rope swings hanging from the trees, ready for some fun in the lake for the next young visitors.
Through the trees we spotted a swan and its cygnets gliding across the water.
After walking round the lake we braced ourselves for the steep climb back to Sutton Bank and as it was our anniversary, Mr B and I headed for lunch at the very nice Carpenters Arms in Felixkirk, just down the road.
This whole area is steeped in history and folklore. I first read about Lake Gormire, amongst other local places, in a fascinating book called The Plot by journalist Madeleine Bunting. It's a layered history of one acre of land near the North York Moors. But I think you could discover the same histories on any other acre of land in the UK and beyond.
Have fun if you do decide to visit!
