In the past Bluebell Hill had two pubs on it. One at the top and one at the bottom. In olden days, before cars were on the roads, there was a single steep track on the hill. Horses were used to pull carriages up and down the narrow track and bells were rung to indicate the movement of the carriages so they didn't meet part way.
One of the pubs has since gone (The Upper Bell). When it was there it sometimes had music playing.
Those are not the Bells your looking for here.
Fairly easy cache to solve for an older Geocacher. The cache can be found at :-
N 51 19.(Glockenspiel) (Mandolin) (Grand piano + Double-speed quitar)
E 000 30.(Bass Guitar) (Mandolin - Slightly distorted guitars) (Spanish guitar + Grand piano)
It is a steep hill walk to the Geocache and back to the recommended parking (the starting point of this cache). There are some great views at the parking. Best to use the way point for the path on the way down and up.
