About Mawnog
Tucked away in the undulating moorland of the Pumlumon range, this 519-metre hill embodies the quiet solitude of Central Wales. Expect pathless, grassy terrain that stays true to the summit’s name. From the top, you gain clear perspectives across the Rheidol valley toward the main Pumlumon massif and the remote Nant-y-moch reservoir.

Did You Know?
- •The name is derived from the Welsh word 'mawn', meaning peat. A 'mawnog' is specifically a place where peat is found or was historically cut, reflecting the deep blanket bog that covers much of this plateau.
- •This summit sits within the so-called 'Cambrian Desert', a vast area of Mid Wales known for its extreme lack of roads and permanent settlements, offering a level of isolation hard to find elsewhere in the UK.
- •From the higher ground, there are excellent views west toward the Nant-y-moch Reservoir, a large man-made lake created in the 1960s as part of the Rheidol hydroelectric power scheme.
- •If the ground feels suspiciously soft underfoot, the hill is simply living up to its name; the local peat can be deceptively deep, especially after a typical Mid Wales downpour.
