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.

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.

Bristol Zoo Project is a wildlife conservation park in South Gloucestershire, run by Bristol Zoological Society. It covers a large site, and its areas are designed to link ecosystems and conservation programmes around the world. Current areas include Bear Wood, Benoué National Park and Discover Madagascar.

The Helicopter Museum near Weston-super-Mare is billed as the largest dedicated helicopter collection in the world, with more than 80 helicopters and autogyros, civilian and military, on display under cover. Highlights include two Queen's Flight helicopters, the Westland Lynx G-LYNX that still holds the helicopter world speed record, a Vietnam-era Huey and a Russian Hind gunship.

Tip: Parking is free, and the museum is a few minutes from Junction 21 of the M5. Book air experience flights online in advance.

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.

SS Great Britain is a museum ship on Bristol's harbourside, designed by Isambard Kingdom Brunel. When launched in 1843 she was the largest passenger ship in the world, and one of the first iron, propeller-driven ocean liners.

Tip: Parking is available at the Maritime Heritage Centre car park next to the site, and you pay at the ticket desks. The Long Ashton Park & Ride is an alternative Monday to Saturday.}

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.

Gough's Cave sits in Cheddar Gorge on the Mendip Hills. The first 820 metres are open to the public as a show cave, and this stretch holds most of the cave's more spectacular formations. It runs on to Diamond Chamber, the end of the show cave today.

Tip: Combine your visit with the Cheddar Man and the Cannibals Museum in the Gorge, where you can see a replica of the Magdalenian remains.
