Pea gravel isn't angular @grantcstewart - it's quite rounded, but very useful for heavier soil too. The sand is important though - it needs to be the gritty type. You could make the problem worse if it's builders' sand. Just putting a layer of 'stuff' on top of heavy clay won't work either if the clay is solid lower down. The best way to amend and improve clay is to add organic matter - well rotted manure, compost , leaf mould etc. That improves the soil structure.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
