You are not doing very well at spelling Cornish locations my 'ansum' :-)
Lands End isn't as much of an attraction as its made out to be unless you like tat for the mantle piece. Nearby Sennen Cove and Gwenver beaches are nice.
If you have some younguns with you, a reel of cotton and a bent dolly pin gets hours of fun in rockpools using prised off Limpets for bait.
If you like walks Park up in ST. Just and have a stroll down to Cot Valley beach then maybe a cliff path across to Cape Cornwall and back to St. Just. Or you can hire push bikes from a shop on the corner of Chapel Roa
