Hi Watto, there are many routes up Gable from Wasdale.
It is a lovely walk up to Sty Head Tarn, and from there you have a choice of
a few routes...
1. Up via Aaron Slack, which is the route in between Gable and Green Gable, and
whilst there you could nip up Green Gable. From Aaron slack to Great Gable there
is a scrambly bit and the actual Aaron Slack path is quite rough and bouldery at times.
2. UP via Beck Head, which is inbetween Gable and Kirk Fell. From Beck Head there
is a very scrambly bit up to the top, and one time in Novemeber I had to turn back because
of the very coldness and slipperyness of the rocks. I don't like this way tbh.
3. Via the Climber's traverse... which is a very difficult path to find sometimes tbh. I have
met many people who have not been successful with this one, due to the feeling of
exposure and the route finding difficulties. The first time I did this I was successful because I followed someone who had been there before.
4. UP via the tourist route from the Stretcher box at Sty head tarn. It is a bit of a slog, but it
is my favourite way up, because of the feeling you get when you are getting higher and higher,
you can feel it happening, at each step up and the views are just marvellous!
Just recently I went up via the tourist route and descended via the Aaron Slack route. The Aaron slack path has a lot of rubble and is quite rough, but when I could I trotted alongside a stream on the right, which was better going for my dog's feet.
I use the tourist route in winter as the fastest form of ascent for the Remembrance Day service.
Great Gable is a lovely fell to climb, but some of the paths are very eroded now. I hope you get fab weather, and in my opinion it's one to be enjoyed and savoured in good weather both for the aaspects of slipperyness and the views.
