Good selection of cakes, coffee & snacks. Great stop off after a bike ride or hike.

Lovely mix of fire road to start with and then a huge climb up and over into a valley that time forgot - perfect single track - although can be a bit muddy in places. Probably best to make sure there has not been too much rain in the week before riding this route - and in the winter be prepared for quick changes of weather and plummeting temperatures.

Capel Soar Y Mynydd is the most remote chapel in Wales. An invaluable spot to find some shelter on longer trips!

A nice easy route for walking or riding, So glad the track across the dam is now open again, just have to keep your eyes open for the dog shit left all over the place.
