Hi, I know EXACTLY where you are on this map, (your arrow). I have spent 15 yrs of summer hols in corfe castle, just down the road, what are you EXACTLY wanting to know. The smaller together the lines, the steeper the hill. The wider the gap between the lines(called contour lines) the easier the steepness (if theat makes sense!!) Are you planning a walk? If you zoom to 1:25,000 it'll show the names of the major bays. Let me know if you need some more specific info. Last summer I walked along the coast from St Aldhelm's west up to Kimmeridge Bay, past the re-sited Clavells tower. Beautiful coast walk, with FAR too much up & down for my liking!!LOL!!
