This is one of my favourite walks on Arran for families, and not too strenuous for anyone. The Machrie Moor standing stones are beautiful and impressive and honestly, a little bit magical. Highly recommend.
Conic Hill has truly beautiful views overlooking Loch Lomond. It is tricky for little legs towards the top with the loose stones, but it’s a great few hours out and the views make it well worth the trip.
We love visiting the Wallace Monument. The kids had a great time climbing the monument and playing on each floor. It’s surprisingly child friendly, and that view from the top is totally worth the climb. The walk up the hill is lovely too.
