Westonbirt and the gardens round Tetbury
Westonbirt, the National Arboretum, near Tetbury, is the big day out of the South Cotswolds: 15,000 trees, a 300m treetop walkway that works for wheelchairs and pushchairs, and Silk Wood, where dogs can run off the lead. Autumn colour peaks from late September to mid-November, when you should book ahead. Volunteer-led walks through the Old Arboretum leave at 11am and 2pm every day, with an extra walk at 11.30am from 1 October to 15 November, when a place costs £1 to book.
Close by, Highgrove's gardens open only by booked guided tour from April to September, with tickets on sale in March, and Rodmarton Manor, the house Ernest Barnsley and local craftsmen built by hand from 1909 to 1929, opens on Wednesdays, Saturdays and bank holidays from May to September. Chavenage House, Trenwith in Poldark, takes visitors by reservation only, and in August 2026 its owner said filming left little chance to tour the house.
Lacock, Dyrham and Malmesbury
Lacock Abbey, the National Trust's abbey made from a medieval nunnery, is where Fox Talbot made the earliest surviving photographic negative in 1835. The museum, the abbey and the village's four streets fill a morning. The abbey rooms close from 1 November to 1 March, apart from the Great Hall at Christmas.
North of Bath, Dyrham Park has William Blathwayt's baroque house of the 1690s, a 270-acre deer park with long views and a play area, open every day but 24 and 25 December. In Malmesbury, the Athelstan Museum in the Town Hall tells the stories of King Athelstan and Eilmer the flying monk. It is free, with a lift, and dogs are welcome.
Sport on summer weekends
Beaufort Polo Club at Westonbirt lets spectators watch free every weekend of its summer season, from late April to mid-September in 2026, with picnics and dogs on leads welcome. Only the Beaufort International charges. Castle Combe Circuit, half a mile from the village, holds race days from spring to November, with under-16s free.
Prices, parking and dogs
The Athelstan Museum and the polo are free. An adult pays £15 at Rodmarton, £19 to £22 at Westonbirt in autumn, £21 at Lacock and £23 at Dyrham (2026). Lacock and Dyrham charge non-members to park, £5 and £4 a day (2026). Rodmarton's car park is free. Dogs are welcome in Lacock's garden and Westonbirt's Silk Wood, but not at Dyrham, because of the deer, nor at Highgrove or Rodmarton. Without a car, take the X34 bus from Chippenham to Lacock. Westonbirt is cheaper if you arrive by bus, train or bike: £13 on weekdays and £15.50 at weekends in autumn 2026. For the town and its gardens, see things to do in Tetbury, and for lunch, places to eat in the South Cotswolds.
In July, Sherston Boules Festival closes the village High Street for a day, and on Boxing Day morning the Marshfield Mummers perform their play along Marshfield's High Street. Lacock is the last stop on our film locations drive, for Hogwarts, and a week in the Cotswolds ends with three nights in Malmesbury for Westonbirt, Castle Combe, Biddestone and Lacock.
