Wiltshire or the County of Wilts is situated in the south west of England and borders the counties of Dorset, Somerset, Hampshire, Gloucestershire, Oxfordshire and Berkshire. Along with the rest of South West England, Wiltshire has a temperature climate which is generally wetter and milder than the rest of the country. Wiltshire, mostly rural, is made up of high chalk downlands, limestone downlands, wide clay valleys and dales providing a beautiful rolling landscape. There are two rivers named Avon that flow through Wiltshire the Bristol Avon and the Hampshire Avon. The largest vale is the Avon Vale with the Bristol Avon cutting diagonally through the north of the county, flowing through Bradford-on-Avon and into Bath and Bristol. The Hampshire Avon rises at Pewsey in Wiltshire flows through the City of Salisbury and the county of Hampshire before entering the English Channel in Dorset.  The Vale of Pewsey cuts through the chalk into Greensand and Oxford Clay in the centre of the county. The Vale of Wardour is in the south west of the county and to the south east are the sandy soils of the northern most area of the New Forest. The highest point in the county is the Tan Hill-Milk Hill ridge at 295 m (968ft) in the Pewsey Vale just north of Salisbury Plain. Wiltshire is known for its pre-Roman archaeology and the Mesolithic, Neolithic and Bronze Age people built settlements on the hills and downland. Stonehenge and Avebury are the most famous Neolithic sites in the UK. The largest area of chalk is Salisbury Plain a semi-wilderness used mainly for arable agriculture and by the British Army as training ranges. The famous Stonehenge, Avebury stone circles and other ancient landmarks can be found on Salisbury Plain. Wiltshire has many country houses open to the public including Longleat near Warminster and the National Trust’s Stourhead near Mere and the City of Salisbury is known for its mediaeval cathedral.

The Cotswolds are a range of hills covering an area of 25 miles across and 90 miles long and lie mainly within the counties of Gloucestershire and Oxfordshire but extend into parts of Wiltshire, Somerset, Worcestershire and Warwickshire. The spine of the Cotswolds runs southwest to northeast through the six counties particularly Gloucestershire, west Oxfordshire and south western Warwickshire. The Cotswolds have been designated as the Cotswold Area of Outstanding Natural Beauty and is the largest AONB in England and Wales. The northern and western edges of the Cotswolds are marked by steep escarpments down to the Severn Valley and the Warwickshire Avon and this escarpment is often called the Cotswolds Edge. On the eastern boundary lies the city of Oxford and on the west is Stroud. To the southeast the upper reaches of the Thames Valley and towns such as Lechlade, Tetbury and Fairford mark the limit of this region and to the south the boundary reaches beyond Bath and towns such as Chipping Sodbury and Marshfield. The Cotswolds are characterised by attractive small towns and villages built of the underlying Cotswold stone, a yellow limestone, and drystone walls many built in the 18th and 19th centuries can be seen everywhere in the fields. The most well known towns or villages are Bourton-on-the-Water, Broadway, Burford, Chipping Norton, Cirencester, Moreton-in-Marsh, Northleach, Stow-on-the-Wold, Stroud and Winchcombe. During the 13th – 15th centuries the native Cotswold sheep were famous throughout Europe for their heavy fleeces and high quality of wool. Cotswold wool came at a high price and the wealth generated by the wool trade enabled wealthy traders to leave their mark by building fine houses and beautiful churches, known as “wool churches”. Today the sight of the sheep on the hillside is still one of the most common features of the Cotswolds.

Slaughterford is a small village about 5 miles west of Chippenham, in the Cotswolds, Wiltshire. The village is a crossing point of the river By Brook in a wooded valley between Castle Combe and Box. The 15th century church of St Nicholas is Grade II listed. It was partly destroyed by Richard Cromwell’s troops on their way to Ireland in 1649. It was left in ruins until it was rebuilt in 1823 then had a further restoration in 1883.

The By Brook is a small river and a tributary of the Bristol Avon. It is 12 miles long and its sources are at Tormarton and Cold Ashton and join just north of Castle Combe. The river flows through the village southwards through the village of Ford and on through Slaughterford. It then runs south westerly past Shockerwick House before joining the Bristol Avon at Bathford. A variety of flora and fauna is supported by the river including the endangered white-clawed crayfish. Twenty watermill sites have been discovered on the river but now none remain in use.

The Macmillan Way is a 290 mile long distance walk linking Boston in Lincolnshire to Abbotsbury in Dorset. The route follows existing footpaths, bridle ways and byways with only short stretches of minor road. From Boston the path heads to Stamford, then by the shore of Rutland Water to Oakham then on to Stow-on-the-Wold via Warmington then through the Cotswolds to Bradford-on-Avon, through Somerset and into Dorset via Castle Cary and Sherborne to Abbotsbury on the coast. The path links to the Viking Way, the Thames Path and the South West Coast Path.
