A few possibilities for places to visit and would be good to get pictures of the cars together.
The Sound, has a nice Cafe, overlooking the Calf of Man
The Lady Isabella (the largest working water wheel) also know as the Laxey Wheel. A couple of nice pubs just below the wheel.
Niarbyl, again just picturesque with a nice Cafe
And one for the bikers among you as well – The Bungalow, just along the Mountain Mile on the TT Course
