Mawddach Estuary has a lot to see, ie:
Arthog side:
– Llynau Cregennen (hunt the little cave and the megaliths?)
– The Blue Lake and derelict quarry, amazing views over Llyn Peninsula. Old quarry looks like somehwere giants lived and built.
– Walk the railway bridge into Barmouth from Morfa Mawddach, (pay the Bridge Troll), get pizza or ice cream etc
– Family cycle from Fairbourne beach up the Mawddach Trail (old railway line) along the estuary to Dolgellau for lunch in the amazing Roberts café, which itself is something else. Upstairs is huge if it’s busy downstairs.
Or do it it the other way around, ie start in Dolgellau, big breakfast, then stop a while Barmouth and chill on the beach before cyling back up the estuary birdwatching, pub stop etc etc.
Along the trail there is an RSPB station and also picnic stops with shade. It’s a beautiful area and well worth exploring.
As said, Cader Idris is the obvious climb. Pony Trail to summit and back (5hrs) or Minffordd Path up to armchair lake and back (2.5hrs). both very different walks, the first dry, rocky, long and quiet with huge 360 views (weather permitting, rare to be clear) to the coast. The latter is short, watery, tree-ful and noisy, I did the Minnfordd as a little kid and it seemed just about right. Lots of torrents and small waterfalls on the way.
