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.

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.

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.

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.

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.

Newquay Zoo is a 13-acre zoo and garden site in Trenance Leisure Park, in the middle of Newquay. It is the largest zoo in Cornwall, and its planted grounds have won a Britain in Bloom Gold award. Visitors can see hundreds of species, including lynx, penguins, otters, zebras, sloths and meerkats, in a mix of indoor and outdoor habitats.

Tip: Check the zoo's website for current opening times, ticket offers and parking details before you go, as these can change.
