Hi, I have camped at the Rugby club since its first time great place. As others have said you can get under the road at Quarterbridge but may get wet feet. As Scaramanga said look on google earth there is a track that goes from the corner of the site behind the clubhouse through some lovely houses then turn right and follow to the dip of Bray Hill, great viewing from there you can walk through the houses up the hill to the crossing point at st ninians maybe 30 mins walk.
