This is a wonderful are for horse riding in the stunning natural location of Chiltern Hills and Ridgeway. There are bridleways which makes this a comfortable route for your horse although in the winter if the ground is not frozen, it is quite luckily to be muddy and in the summer you will need to watch out for nettles.
I highly recommend that you be an experienced rider before heading on these trails. It is a circular route which makes it convenient for getting home. With this route you will have to ride 55km so much sure you are fully prepared (as is your horse).
This is an area of exquisite beauty and this route is only a small sample of its natural beauty.
