Every time I pass it on the train, I think, that looks like a nice place to live... So does anyone have any info, other than it being next to the Teign estuary.
a great view across Lyme Bay (on a clear day people say you can see Portland from the Ness)
There's also some kind of little castle thing with landscaped gardens that's open to the public. Keep meaning to go there and have a look round.
You can.
I'm not totally convinced. At 100m height you can see just over 20 miles, ish (eg. you can clearly see the coast of France from the top of Dover castle) but Portland is at least 40 miles across the bay from the Ness, and the Ness can't be more than 100m tall (probably less tbh), so at least in theory Portland must be too far away to really see one fom the other. I suspect what can be seen is a sort of refracted/reflected version of Portland from just over the horizon.
You need to factor in the elevation of the highest point on Portland Bill too.
