Just a short drive, or walk, from Tywyn and you are in the heart of one of the most beautiful valleys in Wales. Nestling at the foot of Cadair Idris stands the ruins of a romantic Welsh Castle, Castell y Bere, an ancient church, St Michael's in Llanfihangel-y-Pennant, and, close by in the Fathew Valley, the beautiful Dolgoch Falls. Continue up the valley passing the lovely village of Abergynolwyn and you will come upon one of the most beautiful lakes in Wales - Tal-y-Llyn.
The Dyssini River flows through the valley from the east before spilling into Cardigan Bay close to Tywyn. To the north west sits the massive mountainous block of Cadair Idris including Mynydd Pennant and Pen y Garn. To the south east sits the huge rock known as Craig yr Aderyn and a pass cuts through the hills to the village of Abergynolwyn.
