While there has always been a footpath in the woods on the opposite side (which is part of the route of the Cader Race which is run every May from the town to the summit), recently there have been a couple of footpaths and boardwalks added which means you can now walk around the lake from the main road.Parking is tricky, so unless you’re staying at the hotel, you should probably park at Tŷ Nant car park and walk down the road past the hotel and then turn left at the sign and follow the boardwalk around the back the lake. Once you have passed the lake you can either follow the other boardwalk back up the field to the road or follow the race route through the woods, over the farm fields and back to Tŷ Nant(which is prettier if a bit trickier to follow when you reach the farm fields). The route around the back allows lovely views of Cader Idris over the water and you can also get some nice photos from the water’s edge.
Just after you walk down past the hotel you will see several tank traps in the undergrowth over the low wall on your left. These are remnants of World War Two and were built to slow down any invading German tanks. There are some of these on the Mawddach Trail and a few in the surrounding area.
