From the start, take the path signed ‘Roman Steps’ heading south through woodland and L up the Roman Steps. For the first swim turn L at SH 653302 after 1 mile/1.7km and drop down to the western end of Llyn Morwynion. After swimming the length, turn R and head south-east uphill back to the path. If you decide not to swim you can continue on the Roman Steps path to reach this point. Turn R onto a smaller path to Llyn Du. Swim across or run around to the L and then join the path to the summit of Rhinog Fawr at 720 metres (2.6 miles/4.1km). Return down the same path to Llyn Du. Either swim to the western end or run along the southern shore and then navigate vague paths north-west to Gloyw Lyn. Swim north or run the eastern shore to the northern end. Join the path heading north-east and down into the woodland towards Cwm Bychan and pick up the outbound path to return to the start.
