We did this route on the 20/12/2020, last trail of that year!
There is no parking, you can park there,so it can be packed easily.
As usual we did the trail the other way around and in winter.
Until Mangerton, everything is nice and there is a trail, it is true that the trail goes around the edge, so you will have to find your way till the cross (that part is boggy, since is flat and at the top), from there to Stoompa the path comes and goes, but it is not hard to get there. Descending form Stoompa is straight forward, you just go down the mountain.
Once you are at the level of the last lough, you will start to find some boggy places, and then you will find the river which it is not narrow and as we were on winter, well it had quite some water. So we had to cross it the best way we could, be aware that the stones are slippery and that you may be have to walk inside the river as a safer way to cross it. The alternative is to go along the river and walk around 6-7 km more on the road to come back to the car park.
I would like to try it in summer, since it may have less water and maybe it is easier to cross the river then.
