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.

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.

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.

The BIG Sheep is a farm park and theme park in Abbotsham, North Devon, built from the old buildings of a family farm. It is best known for its live shows, including the World-Famous Sheep Race, the Duck Trials and the Sheep Show.

Tip: Pre-book tickets online, as the park gets very busy in school holidays and term time, and booking ahead is cheaper than paying at the door.

The National Marine Aquarium sits in Sutton Harbour, near the Barbican in Plymouth. It is run by the Ocean Conservation Trust, a charity, and is split into four zones: Plymouth Sound, Eddystone Reef, Atlantic Ocean and Blue Planet. You'll see local sharks, rays and octopus, a jellyfish exhibit, and a huge Atlantic tank holding around 1,000 Caribbean fish, with lemon and sand tiger sharks.

Tip: Pre-book your tickets online, as entry can't be guaranteed without a booking, especially at weekends and in school holidays.

The Milky Way is a family-run adventure park on a former dairy farm near Bideford.

Tip: Book tickets online in advance, especially in school holidays, and check the calendar for opening days and times.
