Several places to park all across the park, they charge Cars at £3.00 per day.
Clue is in the title, Dassett Hills, it's a group of hills in the Warwickshire countryside. There are well walked pathways across the Hills but it's a free roam place, so you can walk as little or as far as you want.
No water here
Various bins across the park.
Highly Recommend the Yew Tree Pub a mile or so down the road in Avon Dassett www.theyewtreepub.co.uk - very dog friendly, great food and large beer garden and they also have an ice cream hut in the summer.
This isn't the longest of walks but it's deffinately worth the trip (www.countryparks.warwickshire.gov.uk/homepage/4/burton-dassett-hills). As you can see from the photo's the sunsets are spectacular. It does get a bit busy on clear evenings but you can usually find parking spaces even at peak times. You could spend half a day quite easily here, walk the hills, have a picnic (lots of picnic benches etc spread across the park), fly kites, play games. There are sheep grazing a lot of the time so dogs need to be kept on a lead etc.
