Dartmoor Zoological Park is a 33-acre zoo just north of Sparkwell, on the south-west edge of Dartmoor in Devon. It is run by a charity that focuses on conservation, education and research, and it belongs to BIAZA, the British and Irish Association of Zoos and Aquariums.

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.

Adrenalin Quarry is a family-owned adventure park in Menheniot, built around an old flooded quarry. It offers five rides: an inflatable aquapark for ages 6 and over, go karting on an 800m all-weather track for ages 7 and over, a zip wire that is 50m high and 490m long, a giant swing 150ft above the lake, and axe throwing for ages 12 and over.

Tip: You can book all rides online ahead, or just turn up for the zip and the giant swing.

Buckland Abbey was founded as a Cistercian abbey in 1278 and later became the home of Sir Francis Drake. Unusually, the church was kept as the heart of the house when it was converted. Explore the Grade I listed building, where Drake's Drum is part of the collection, then see the medieval Great Barn next to the house.

Tip: Dogs on leads can go almost everywhere except the Kitchen Garden, but only assistance dogs are allowed inside the Abbey. Parking is free.

The Plym Valley Railway is a heritage railway on part of the old Great Western line from Plymouth to Tavistock, which closed in 1962. Trains run from Marsh Mills station to Plym Bridge, a journey of about 1.5 miles of track. Marsh Mills is also a railway centre where volunteers preserve and restore steam and diesel locomotives, carriages and wagons.

Tip: There is no parking at Marsh Mills station, but the Coypool Park and Ride car park is directly opposite and can be used by railway visitors at weekends.

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.

Restormel Castle stands on a high, deeply ditched mound overlooking the River Fowey near Lostwithiel. Its huge, almost perfectly circular keep is one of the best-preserved of its type, and it was once a luxurious residence linked to the Earls of Cornwall and Edward the Black Prince.

Tip: Bring a picnic to enjoy at the castle, and combine your visit with a walk in the Fowey valley.

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.
