There is a little cafe above the main car park for a coffee and cake after the "gift shop" labelled walks. As usual, Komoot makes the walk easier than using signposts - remember to download to the phone app. Kayaking/canoeing around the lake is only possible for about half of it due to a protected bird sanctuary.

Llangower provides access to the lakeside for walks, picnics and bird watching. The stop also offers access to the car park and adjacent toilet facilities provided by the Snowdonia National Park. There is a passing loop and small signal box here which is used on gala days and for the pink timetable to allow trains to pass. A beautiful little picnic area for a stop and a break before cycling them hills again.

A circular walk through the historical Nannau estate and along the shore of Llyn Cynwch The Precipice has a fantastic array of qualities. From habitats such as woodlands and meadows to captivating views of Snowdonia’s mountain ranges. The path will take you through part of the Nannau estate which dates back to the 12th century and is steeped in fascinating Welsh history. The route ends on the shores of Llyn Cynwch—a working reservoir that provides nearby Dolgellau with water.
