If you are unfortunate to get a pitch close to the road then you,lll be pleased to know that at around midnight the noise subsides (but only until about 5 a.m.) the rest of the time traffic noise is constant. That was the only down side for me, the wardens are really great and the walk into Henley is easy as is catching the bus to Marlow. Both delightful towns, Hemel Hempstead however is perfectly missable. Would I stay at this site again - yes, though I would try and stay towards the rear of the site. There is also a superb walk to be found along the river bank.....walk towards Henley and take the path opposite the rugby club and your on the banks of the Thames with only boats and wildlife.
