A fairly steep descent from the western side, but the reward is a lovely waterfall and large pool

Great walk through a variety of tree species and easy to follow path. Would recommend going anti clockwise/reverse of suggested route as scenery coming back through gorge is stunning (with the bridge as a nice suprise at the end) and easier downhill as plenty of small steps. If taking a dog then be aware there is/are sheep grazing along the route but no stiles or fences to climb if you have a large dog but there are very steep banks/drops along the gorge so recommend keeping on a lead if they are a bit hectic! Would not recommend unless you have a basic level of fitness as some parts of the path are extremely steep.

Nice place to stop: coffee and cake, but also hearty food

Llyn Mair (Mary's Lake) is a Victorian decorative feature said to have been built by William Edward Oakeley for his daughter. In addition to an extravagant gift, the lake began supplying hydroelectric power to Plas and other surrounding villages in 2013. (Woodland Trust)

This remote and ethereal ancient oak woodland was once part of a historic estate and slopes gently towards Llyn Mair (Mary's Lake). A network of trails offers spectacular views across Snowdonia National Park, while steam trains from the iconic Ffestiniog Railway wind along the border. With rare wildlife and an abundance of beautiful flora, Coed Hafod y Llyn is the perfect forest destination for train enthusiasts and nature lovers. (Woodland Trust)

As of 24July 2023 this bridge is closed and many of the boards are missing. The detour down to the main road adds about 1 mile.
