Heading east from Devizes the canal passes through the Wiltshire countryside and a series of locks and swing bridges before another flight of locks at Crofton.

At Honeystreet is the remains of a wharf that was the home of boat builders Robbins, Lane and Pinnegar, which served as the boat building headquarters of the Canal Company. They built many of the boats used on the canals of southern England before closing in about 1950. Next to the wharf is the Barge Inn, a substantial public house once known as the George Inn. It was roughly half-way along the canal and served as a bakehouse, slaughterhouse, and shop for provisions for those living and working on the canal. The building was destroyed by fire in 1858 and rebuilt within six months. It was built just within the parish boundary of Stanton St Bernard to "serve the Honey Street wharf in Alton parish, which refused to allow drinking establishments".

Jones's Mill is a 29-acre (12 ha) area of fen vegetation, scrub, and woodland lying along the headwaters of the Salisbury Avon northeast of Pewsey. It has been designated a biological Site of Special Scientific Interest because it is "the best known example of a calcareous valley mire in Wiltshire".

The four locks at Wootton Rivers mark the end of the climb from the Avon. Between Wootton Top Lock and Crofton is the summit pound of the canal at 450 feet (140 m) above sea level, stretching for about 2 miles (3.2 km) and including the 502-yard (459 m) long Bruce Tunnel. The tunnel is named after the local land owner, Thomas Brudenell-Bruce, 1st Earl of Ailesbury (1729–1814), who refused to allow a deep cutting through his property and insisted on a tunnel. The tunnel has red brick portals, capped with Bath Stone, each with a decorative stone plaque of Bristol Pennant Limestone. The tunnel was begun in 1806 and finished in 1809. It is lined with English bond brickwork and has a wide bore to cope with the Newbury barges used on the canal. There is no towpath through the tunnel, therefore walkers and cyclists must walk across the top of the hill. When canal boats were pulled by horses the boatmen had to haul their barges through the tunnel by hand, pulling on chains that ran along the inside walls.

The Crofton Locks flight marks the start of the descent from the summit to the Thames; the nine locks have a total rise/fall of 61 feet (19 m). When the canal was built there were no reliable water sources available to fill the summit by normal gravitational means. A number of usable springs were found adjacent to the canal route about one mile (2 km) east of the summit pound, and about 40 feet (12 m) below it, and arrangements were made for them to feed the pound below lock 60 at Crofton. Some years later the Wilton Water reservoir was created to enhance the supply to this pound using the springs and the River Dun.

Water is pumped to the summit at the western end of the locks, from Wilton Water, by the restored Crofton Pumping Station. The original steam-powered pumping station is preserved and contains one of the oldest operational Watt-style beam engines in the world, dating from 1812. The steam engines still pump water on selected weekends, but for day-to-day operation electric pumps are used, automatically controlled by the water level in the summit pound.

Near Crofton are Savernake Forest and the remains of a railway bridge that carried the Midland and South Western Junction Railway over the canal. Mill Bridge at Great Bedwyn is unusual in being a skew arch; on its completion in 1796 it was the first of its kind. From there to Hungerford the canal follows the valley of the River Dun through Freeman's Marsh, which consists of unimproved meadows, marsh, and reedbed. It is an important site for overwintering, migratory and breeding birds, and supports many varieties of flora scarce in Southern England. It was cited by English Nature in 1986, and forms part of the North Wessex Downs Area of Outstanding Natural Beauty. There are plans to construct a marina and hotel complex adjacent to the site, but the potential environmental impacts (particularly to water voles) of such a development on Freeman's Marsh have led to local opposition. To the north of the canal are seven separate small areas, four in the Kennet Valley and three in the Lambourn Valley, which make up the Kennet and Lambourn Floodplain SSSI. Occupying a total of 57 acres (23 ha), it supports particularly large populations of Desmoulin's whorl snail.

There are several locks and bridges in Hungerford, including one which carries the A338. Hungerford Marsh Lock is unique on the Kennet and Avon Canal in that it has a swing bridge directly over the centre of the lock that must be opened before the lock may be used. In the area around the lock, called Hungerford Marsh Nature Reserve, more than 120 bird species have been recorded.

Between Kintbury Lock and Newbury, passing to the north of Hamstead Marshall, the canal is very close to the River Kennet, which flows into the canal via several channels. The canal passes through an area known as the Kennet Valley Alderwoods, the largest remaining fragments of damp, ash-alder woodland in the River Kennet floodplain. The SSSI includes two woods – the Wilderness and part of Ryott's Plantation – which are important because they support a very great diversity of plants associated with this woodland type, dominated by Alder (Alnus glutinosa); though Ash (Fraxinus excelsior) is abundant in places and there is occasional Oak (Quercus robur) and Wych Elm (Ulmus glabra). In addition to the wide range of higher plants the woods support a diverse bryophyte flora including the uncommon epiphytes Radula complanata, Zygodon viridissimus and Orthotrichum affine. Nearby is Irish Hill Copse. This site of coppiced ancient woodland includes an extensive area of calcareous ash/wych elm coppice on the hill sides, merging into wet ash/maple and acid oak/ash/hazel woodland with aspen, on the higher parts of the site. The lower slopes are dominated by Dog's Mercury (Mercurialis perennis), with abundant Herb Paris (Paris quadrifolia), Toothwort (Lathraea squamaria), Solomon's seal (Polygonatum multiflorum), Twayblade and Early Purple Orchids (Listera ovata) and Orchis mascula and, locally, Wild Daffodil (Narcissus pseudonarcissus).

A wooden bridge was built close to Newbury Lock in 1726, replaced in stone between 1769 and 1772 by James Clarke, and now known as the Town Bridge or Water Bridge. As there is no tow path, a line to haul the barge had to be floated under the bridge and then re-attached to the horse where the tow path resumed.
