Beautiful sunny day to climb, although quite chilly for this time of the year.
Temperature at the top was -1°.
In my research beforehand I read that there is not an established path up but I found fairly good paths most of the time.
In order to reach the north "peak" you need proper waterproof boots and gaiters as the access is very boggy.
Up and round from Llyn Arenig Fawr
Ascended with Ken on a day trip to Wales from Liverpool. Wet start then driving hailstones on the trail to the Lynn. At the Lynn, Ken was surprised to see that there was a puddle of water inside the bothy. We carefully crossed the reservoir spillway as the water was surging close to the iron ladder. After that the rest of the ascent was uneventful. We only saw one other person.
I really like this mountain, although its not as high and dramatic as the other peaks in Snowdonia it more than makes up for it in wilderness.
