Hi there we stayed in Trevornick park a couple of years ago (it's in Holywell Bay, Newquay, i think there's another big park down the road from it) We didn't take our dogs as we were staying in one of their eurotents and dogs weren't allowed in them, but there were people with dogs there. I think certain areas were allocated for people with dogs to stay.
We had a great time although the was a very uphill trek to access the beach, i think there was a slightly less steeper way but it took longer to get on it.
There was loads to do though there, a funpark, swimming pool, fishing etc it was great. I'd love to go back there :-)
