some epic biking roads
just follow the coast and you cant go wrong a82 up loch lomond, a83 from tarbet round loch fyne to lochgilphead
a816 up to oban, detour to crinan ferry if you want, oban great place to stay for beers, whisky, seafood..campsite just outside town overlooking isle of kerrera if you are camping..otherwise plenty of B&B's and a very grand youth hostel with amazing view over the bay
follow the coastal route if you want or head back inland depending on which way you want to see glencoe..its amazing either way and a must if you are on bike, again detour down to glen etive from the a82 if you want to see some amazing sights..its a single track road, little used and doesnt even have a number..but well worth it
head on up to skye...from there you are limited by the road network..or lack of it a832/835/836/890 are about the only roads..and they just keep on going! but they are A roads in name only, vast swathes of them are single lane with passing places..only a bike can really make rapid progress.
just miles and miles of bugger all, bogs and midgies
