If you go to StreetMap.co.uk you can zoom out to see footpaths (short-dotted lines in pink) and bridleways (long-dotted lines in pink). You could do a search on Hutton and then just grab and move the map around to cover your area.
Theres loads of bridleways theres what we call 100 acres which takes u down into Loxton if ur coming from plantations theres also the bennetts ride which are 2 open field but u must stick to the path and that takes u into Loxton but Bleadon end u get to these paths when u go up the really rocky hill with the sheep in the field next to it and turn off the first gateways to 100 acres and the one abit further down the path is for bennetts hope this helps really hard to explain but theres some really nice riding!
Scratchy lane joins Canada coombe/Roman road to plantation. Puddle lane leads towards Banwell from plantation then go right and lanes back through Christon, up weston lane to rejoin plantation, or from plantation down 100 acres, bit of roadwork to crooks peak.
I,ve just looked on www.bridlewaymap.com====and there does not seem to be a lot around your area .Go into a good bookshop or large W.H.Smiths and seek advise on ordnance survey maps.
