Hi Mike,I would recommend a "go explore ticket" it gets you unlimited bus travel and includes steam train and electric trains, which can give you more options when in Ramsey,or Port Erin or Laxey,you can get them at the sea terminal,Douglas steam train station,or Mannin centre Peel.Given the fact you are at braddan bridge campsite,just walk down to kirk braddan for frequent buses to Peel and Ramsey,or walk over quarter bridge,past Mc Donald's then turn right over bridge at big power station,there is a bus stop that will take you to the south.about 20mins walk from campsite.Also from site you could walk up to Johnny Wattersons lane to Cronk Ny Mona,great views,and handy pub,(the cat with no tail)and shops .and during road closures,from there you can walk down past pub,left into,Snaefell rd, into School rd,past Manor hotel (nice old pub)into Greenfield rd,then you are at the start/finish line,then you go into cemetery ,over metal bridge into grand stand area.nb the buses are really quite frequent and good.
