RE: advice on mountain climbing??
As long as you've got two legs, you'll make it to the top. Depending which route you go will depend on the severity. There's actually no climbing involved, just walking. In October you'll need some warm kit, waterproofs, sturdy footwear and preferably some scoff and a flask of hot whatever. There's a cafe on the summit so you can get a bite to eat and drink once on top.
