Diggerland is a theme park where children and adults can ride, drive and operate real diggers, dumpers and other full-size construction machinery. The Devon park is in Cullompton, and the whole line-up runs to around 20 rides and drives.

Tip: Check the ride height chart on the Diggerland website before you go, so you know which rides each child can enjoy.

Castle Drogo is a country house and mixed-revivalist castle near Drewsteignton, built between 1911 and 1930 and known as the last castle built in England. Edwin Lutyens designed it for Julius Drewe, the founder of the Home and Colonial Stores. It is built of granite and overlooks the Teign Gorge. The castle is Grade I listed and the gardens are Grade II* listed.

Tip: The car park has limited spaces, so if it is full, come back another time rather than parking along the drive, which blocks farm vehicles.

Paignton Zoo covers 80 acres of animal enclosures and gardens, and most families spend a full day here. You can follow the four zones (Wetlands, Islands, Grasslands and Rainforests), catch the daily talks and feeding sessions, and wander through nature trails in Clennon Gorge wildlife reserve.

Tip: Book tickets online ahead of your visit to save money.

Exeter Cathedral has stood at the heart of Devon for nearly a thousand years. Its Norman towers and Decorated Gothic interior are topped by the longest uninterrupted medieval stone vaulted ceiling in the world. Inside you can see the 15th-century Astronomical Clock and an early set of misericords, and guided floor tours and audio guides help bring the building to life.

Tip: Head for the Treasures Exhibition tour or a guided floor tour, both included in standard admission, though floor tours are subject to availability.

Powderham Castle is a fortified manor house six miles south of Exeter, on flat ground beside the Exe estuary. The medieval core dates from after 1390, and the house was extended and altered in the 18th and 19th centuries. It has been home to the Courtenay family, Earls of Devon, for centuries.

Tip: The main public entrance gates are in the village of Kenton, so head there rather than to the castle's other side.

Killerton is an 18th-century house near Exeter, cared for by the National Trust and shown as a comfortable family home. Inside, period rooms display a collection of 18th- to 20th-century costumes, and there is a fashion exhibition on the first floor.

Tip: Dogs on short leads are welcome everywhere outside and in the Stables Coffee Shop, but only assistance dogs are allowed in the house and the Kitchen Café.

Otterton Mill is a working watermill beside the River Otter, near Budleigh Salterton. A mill has stood here since the Domesday Book, and the old workings are free to look round, with a self-guided tour and the water wheel kept turning. Flour is still milled using traditional methods.

Tip: Well-behaved dogs on leads can sit outside or downstairs in the café, but only assistance dogs are allowed in the farm shop, gallery and upstairs café.

Okehampton Castle is a ruined medieval castle on a wooded ridge above the swift-flowing West Okement river. It began as a Norman motte and bailey castle, and in the 14th century Hugh Courtenay developed it into a palatial home. You can still explore the remains of his buildings, from the keep mound to the tall gatehouse.

Tip: Wear sturdy footwear for the steps and uneven ground, and note that opening depends on volunteer availability, so it can close at short notice.
