Next morning we went by taxi to Barefeet Naturist Resort, to the north-east of Bangkok city centre. The driver understandably hadn't heard of it, but a quick entry of the address into Google maps on his phone and we were on our way.
Well we thought we were until a few km out we got stuck in traffic. The 25km (40 minute drive) took us 1 3/4 hours! We did make it eventually and were greeted by our hosts Gregers and Dao who showed us to our room. At last we could get our gear off thank goodness.
