Hidden valley wicklow is a great campsite. It is run by a really nice man and his son. You can light a fire on the stones along the river. There are rowing boats and kayaks for hire in the small lake. Or take your own kayak to go in the big river. You can also fish in the river. To hire a kayak is only €5 to park the car is free. 2 people in a tent was €20 a night. Would def recommend it.
