stayed in Trelawne but wasnt impressed.
The site itself was nice, the 1st caravan they put us in was dreadful but after kicking up a stink they upgraded us to gold at no extra cost & that one was very nice!
Looe is lovely & Polperro is pretty - Trelawne is half way between the two places.
The thing that let the holiday down for us was that at the time we were non-drivers. Did the trip by train & had to rely on public transport. Apart from Looe & Polperro there was nowhere else to visit as the buses seemed to stop in looe in one direction & polperro the other.
The nearest train station was Liskeard & that had cost us £20 taxi fare to get to Trelawne when we arrrived so we didnt attempt to go anywhere by train
I think if I had been driving then it would've been a totally different holiday. There is plenty to do around the area - if you can get to it - and the park itself is quite nice.
Sorry if this reply seems a bit vague - if there's anything specific I can help with just pm or email me
