Tropiquaria is a small zoo and animal sanctuary based in and around a repurposed 1933 BBC Radio Transmitting Station at Washford Cross in Somerset. The listed building houses the Reptile House, Aquarium and Nocturnal House, with several acres of outdoor enclosures around it. Outside you can spot animals such as gibbons, ring-tailed lemurs, meerkats, tapir, wallabies and serval.

Tip: Don't leave dogs in your vehicle, as the car park has limited shade; only registered Assistance Dogs are allowed in the zoo.

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.

Dunster Castle stands on a steep hill called the Tor above the village of Dunster, and has been fortified since the late Anglo-Saxon period. Today it is a Grade I listed country house run by the National Trust, with dramatic views and subtropical gardens around it.

Tip: The car park is small and its gates lock at 6pm, so arrive early. In poor weather you may be asked to use Dunster Steep village car park instead.

Cheddar Gorge is a dramatic limestone gorge in the Mendip Hills, with cliffs up to 137 metres deep. A day ticket covers Gough's Cave, Jacob's Ladder and the Museum of Prehistory. Gough's Cave is where Cheddar Man, Britain's oldest complete human skeleton, was found, and its stalactites and stalagmites were shaped by an underground river.

Tip: Arrive before 11am, especially in school holidays and on bank holidays, to find a parking space easily. Booking day tickets online in advance also saves money.

Glastonbury Tor is a conical hill rising from the Somerset Levels, topped by the roofless 15th-century tower of St Michael's Church. Excavations at the summit revealed the plans of two earlier churches on the site.

Tip: There is no parking at the Tor itself, so use the nearest fee-paying car park at Draper and Co on Chilkwell Street and walk, and keep your dog on a lead because sheep graze here.
