"Back to one of my 'special' places. Needed to tick off the nuttall Glasgwm, so decided to do a route I've only ever come down - up the side of the waterfall. Decided on the clock wise route over to Aran Fawddwy and Drysgol from Glasgwm, making my 3rd summits of both. Got my feet wet despite taking care, and ended up with some painful frostnip on my toes due to minus 6 temps, wind chill and snow. I live and learn - always pack waterproof socks, or carry some bags to put feet in ;-) Oh, and put your gaiters on even if you think you can hoverboard over the bogs!
Despite being colder, the weather was quite enjoyable with blue skies and very little cloud. Winds were only around 20kmh. Was one of those days where one minute I'm down to a T-Shirt, then a middle layer, then switching between down and hard-shell jackets." — adventure-stricken • Mar 14, 2026

"I had a very early start today and headed up before sunrise to try to beat the usual crowds and catch a temperature inversion. Wind speed was a little higher than forecast, and the rock was like glass on the mini scramble up to Pen Y Fan summit. In the end, I didn't hang around much and only had a glimmer of hope on Corn Du for an inversion, but the wind chill meant I lost interest and started my descent on ground I hadn't covered before.
Not sure if today was my 7th or 8th summit of Pen Y Fan, but that now concludes my completion of every possible route up and down." — adventure-stricken • Dec 28, 2025
"Had left the 'mountain-forecast' tab open in my browser earlier in the week, and noticed a lovely looking sunny day with minimal wind across Snowdonia on Sunday. It has been a while since I've done a day trip so far away, but I decided to get up at 530am, and do the 3.5hr drive each way to 'seize' the day ;-)
Managed to tick off my last 2 x nuttalls on the Cadair range, and of course felt the need to tick off Cadair Idris for a 3rd time. I was going to do a route from the East, but at the last minute, I changed my mind and came in from the West. This turned out to be a great decision, a very enjoyable and varied route with some absolutely incredible views. One I'll always remember and hope to do again!" — adventure-stricken • Sep 28, 2025
"Run 🏃♂️
Today i was a particularly silly hobbit and only packed 1 litre of water. Twas a 30km run. Ran out of water at 15km…
I live to tell the tale, but my face resembles the pits of Mordor and Ironically, my mouth is as dry as a dragon.
Splendid views, a vast collection of concerned faces and sadly, few warm hellos from fellow adventurers. Perhaps the heat made everyone grumpy…
Alas, till the next time, you dragony bastard." — JKbaggins • Aug 24, 2025
