We spent a great day messing about on the roads around Arrochar, in particular the B839 Hell's Glen road between Lochgoilhead and Loch Fyne (here http://maps.google.co.uk/maps?f=d&source=s_d&saddr=B839&daddr=56.232911,-4.97308&hl=en&geocode=FUKTWQMdiv20_w%3B&mra=mi&mrsp=1,0&sz=15&sll=56.230733,-4.96552&sspn=0.010711,0.027165&ie=UTF8&ll=56.217587,-4.93372&spn=0.042857,0.108662&t=p&z=13)
The road has been completely resurfaced, so if you're descending towards lochgoilhead you have a very long, smooth, fast and pothole free descent through a torturous little glen with plenty of interesting corners, including a switchback sent straight from the Alps.
We were climbing it unfortunately but the descent down the other side had some excellent corners aswell, tight enough to need some care but open enough to get off the brakes and lean in.
The descent from Glen Douglas to Loch Long has also been resurfaced, and is silly fast and steep.
All in all a good day! 😀
