The village is home to the Knowl Hill Primary School, St Peter's Church, a greasy spoon café and a tool shop. There are three fine pubs within the village, the Bird in Hand, "The Old Devil Inn" and "The Royal Oak" (the Seven Stars closed in 2012 and will be converted into three four-bedroom dwellings) and others in neighbouring places, each with its own unique character and history. ;The Old Devil Inn' reverted to its original name 'The New Inn' mid way through 2013 after an extensive re-fit. Situated on the south side of the A4 is Knowl Hill Common, a small hill looking out over Berkshire towards Windsor Castle which can clearly be seen on a nice day. Also on the south side is a small wood known as 'The Clumps', the name coming from two separate groups of trees that were once significantly taller than the rest and clumped in the middle.
Knowl Hill is most famous for the Knowl Hill Steam Rally. This was an internationally known event that was held every August. Unfortunately, due to rising insurance costs the decision was made to hold the very last Steam Rally in 2004. This caused much disappointment in the local community. The Steam Rally provided an enjoyable opportunity for the public to see, and for enthusiasts to show, a wide range of vintage machinery that has been an integral part of the United Kingdom's history. This included traction engines, steam-powered labour machinery, vintage cars and motorcycles and a working railway extraction engine. The event also had a large fun fair, local and commercial food traders, craft and animal-showing tents and helicopter rides.
