About Slieau Lhean
Sitting as a broad, heather-topped shoulder above the Laxey Valley, this Tump offers a quieter alternative to nearby Snaefell. The terrain is typical Manx moorland—often spongy underfoot—leading to a summit that provides clear, earned views across Glen Roy and down towards the Lady Isabella waterwheel in Laxey.

Did You Know?
- •Derived from Manx Gaelic, the name translates to 'Broad Hill,' a fitting description for the wide, undulating ridge that separates the head of Glen Roy from the steep-sided Laxey Valley.
- •The hill is a key waypoint on the ridge route south from Snaefell, providing a grandstand view of the mountain railway as it winds its way up the island's highest peak.
- •On a day of high visibility, the view eastward extends across the Irish Sea to the distinctive peaks of the Lake District, while the summit itself offers a rare perspective of the Great Laxey Wheel from above.
- •While the summit is technically a Tump, the local definition of 'dry feet' is highly subjective here; the broad plateau is a masterclass in how much water a bit of peat can hold.
