Mawddach Trail
The Mawddach Trail (Welsh: Llwybr Mawddach) is a cycle path route, part of Lôn Las Cymru, which runs for some 8 miles (13 km) from Dolgellau (52°44′41″N 3°53′12″W / 52.7446°N 3.8866°W) to Morfa Mawddach railway station (52°42′27″N 4°01′53″W / 52.7076°N 4.0315°W), by Barmouth bridge on the Cambrian coast. It is maintained by the Snowdonia National Park and is popular with walkers and cyclists alike. It passes some estuarine areas that are important for water birds, and the RSPB Information Centre at Penmaenpool makes use of the old signal box as an observation centre overlooking the estuary.
