Moel Gwern-Nannau

The walk up Moel Gwern-Nannau from Bala isn't the most famous route in Snowdonia, which is partly why it's rather good. You get proper mountain air without the crowds you'd find queuing for Snowdon itself. The peak sits at 2,100 feet, which means it's strenuous enough to feel like an achievement but not so brutal that you'll regret choosing it after the first mile.

This is solid territory for walkers. The ascent takes roughly two hours from the base if you're moving at a decent pace, and the views across the Bala Lake basin are genuinely worth the slog. On a clear day you're looking at the Arenig mountains in the distance and the whole valley spread out below you. The summit itself is a bit windswept and exposed, so bring proper kit.

It's not a walk for very young kids unless they're experienced hikers, but teenagers with reasonable fitness levels will find it manageable. The terrain is straightforward enough - no technical scrambling - though it can be boggy in places after wet weather. Allow a full morning or afternoon for the round trip, including a decent break at the top.

Stay at Tyn Cornel Camping just 4.7 miles away, or go upmarket at Porth Eryri Glamping nearby if you want something with a bit more comfort. Either way, Bala itself is a proper little hub for mountain activities. The walk is free, obviously, and there's nowhere to buy food or water at the summit, so come prepared.
