It’s official. Motorbike fans across the country have voted Scotland’s Glen Coe and the A82 as Britain’s favourite scenic biking route in a survey of over 1,500 bikers recently conducted by DVLA Personalised Registrations. Bealach na Ba, situated just off the A696, and the stunning surroundings of the Heights of Kinlochewe found along the A832, were noted as bikers’ second and third most popular routes, positioning Scotland as home to the nation’s top three bike vistas.
No doubt some of the other guys will have there own personal favourites. But hey we are all allowed our own opinions.
