Philip if your looking for a good site around st ives that doesnt get overcrowded in the summer it isnt a good site. Try Polmanter just outside st ives very good site with a pool but with a very good site with a pool it will be very very busy in the summer!!!
When I mean overcrouded what I mean is the pitches Ive seen some where you have hardley got room to put your car and awning up because the people that run the sites are trying to make as much money as possible trying to get as many on as possible but you do see the nice sites where the pitches are the same all year round and not on top of each other
