Forget Tog Hill most of the time as the chavs have found it and it's nowhere near as good as it once was. Better is the car park just off J18 of the M4 on the A46 towards Bath (signposted Picnic Area). There are woods just opposite the entrance to the car park itself where you will find gay action pretty much 24/7 (look both sides of the path opposite the car park) and late at night you'll find couples meeting in the car park, often going on to The Barn for some more private fun.
