Mynydd Ceiswyn

The walk up Mynydd Ceiswyn starts gently enough from the Dolgellau side, but don't let that fool you - it's proper steep in places and the views only get better the higher you climb. Once you're up there, the whole of Snowdonia unfolds: Cadair Idris dominates to the south, and on a clear day you can see right across to the coast. The summit itself is modest - a cairn and not much else - but the sense of space up there makes it worth every step.

This is one for hillwalkers and anyone who wants a proper sense of achievement without needing rock climbing skills. It'll take most people three to four hours there and back from the main approach, depending on fitness. Not ideal for very young kids unless they're already used to slopes, but teenagers and adults will find it genuinely rewarding. The local paths are reasonably well-marked, though a map is essential.

Stay at either Llwyn yr Helm or Torrent Walk, both within spitting distance of Dolgellau town, and you've got yourself a solid mountain break. Combine this with Cadair Idris for a proper two-day walking trip, or use it as a warm-up walk before tackling something bigger. Go early to beat the weather - this ridge catches cloud fast when the wind's from the west.
