I'm a big fan of this mountain, an ascent of the south side of the mountain gives airy views of the moelwyns, industrial archaeology, a nice if boggy lakeside walk, and the highlight of the ascent, the Ddear Ddu ridges offers an introduction to scrambling, and great practice for the tougher scrambles on neighbouring hills. The summit also gives just about the best views of the Snowdon horseshoe going. And you can do the entire walk in just an afternoon, meaning easy highs for relatively little effort.
