A good pit-stop when you are out riding with an old guy called Peter James. Sometimes he'll get the cakes in!

Situated in the beautiful wilderness between the Breacon Beacons and the Black Mountain overlooked by the hills of Fan Fawr and Fan Gihirych, Maen Llia is a truly massive sliver of rock. While it is over 3.5 metres tall and nearly 3 metres wide, it is only 75 centimetres thick and bears a striking resemblance to a giant Neolithic hand axe. Although it is aligned north to south, the sides of the rock become surprisingly warm to the touch on a sunny day. This must have been an important pass between the hills, both to the local prehistoric population and to the Romans who came this way some 3000 years later - they built the road 'Sarn Helen' right by the stone and the current road still follows part of its course.

The River Tawe begins its journey at Llyn y Fan Fawr, which collects the run off from Fan Brycheiniog. It's just a short uphill walk from here to reach the llyn and the impressive escarpment that towers over it. There's plenty of parking on the road.

According to legend, the stone goes down to the river, the Afon Llia to drink on occasion. This tall tale seems likely to be an allusion to the fact that its shadow is cast across the moorland as far as the river when the sun is low in the evening sky.

This road is a firm favourite with those who know it - which is surprisingly few. Enjoy the spectacular views across the Brecon Beacons and Carmarthenshire Fans, with good quality tarmac under your wheels and only occasional car traffic. The approach from Trecastle to the North is about a 7km climb, with an elevation gain of 259m, and an average gradient of 3.7%.
