As with ALL good spots at the TT you have to be there early.  If you park in the road on the right at the top of Barregarrow where the marshals stand you can drive up to the mountain during racing and also to Union Mills and out under the track at Quarter Bridge but make sure you have a map and/ or good satnav. Walking from the top to the bottom is fairly straight forward as you are just following the track but there are various challenging obstacles so wear appropriate footwear. Enjoy the racing.    PS. I'm offering anyone who hasn't been round the track and is without transport a free tour most mornings (Early !!) See my posting on 'Events, Fundraising, Sponsorship' section
