Regrettably there is no camping of any sort allowed on the club grounds. This is because of local government regulations so outside the control of the club. If you are travelling by motorhome, you are very welcome to drive into the club every day.
The nearest campsite to HISC is Fishery Creek. It is 10 minutes level ride by bicycle. It takes motor homes, caravans and tents. This and the other sites taking tourers are listed in http://www.visit-oystercoast.co.uk/ and http://www.resort-guide.co.uk/ .. The other sites are a bit further away, being about 10 minutes drive or 15 to 20 minutes by bicycle.
