The Old Roundhouse

The Milky Way is a family-run adventure park on a former dairy farm near Bideford. It has more than 110,000 sq ft of indoor attractions as well as acres of outdoor space, so a day here works whatever the weather. Rides include roller coasters, indoor dodgems, a mini-train and Ziggy's Blast Quest, an interactive laser shooting ride.

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

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.

Hartland Abbey was founded in the 12th century and is still the home of the Stucley family. You can wander through the house at your own pace, taking in rooms from Medieval to Victorian times, with paintings, furniture and Chinese porcelain collected over generations. Exhibitions cover filming on the estate and the Stonehenge pioneer William Stukeley.

Tip: Hartland Quay is only a mile away, so it pairs well with a visit; the tea room needs a valid garden entry ticket.

The Museum of Witchcraft and Magic is in the village of Boscastle in Cornwall. It is dedicated to European witchcraft and magic, with exhibits on folk magic, ceremonial magic, Freemasonry and Wicca. Its collection of such objects has been described as the largest in the world.

Tip: The museum's website says there is no parking at the museum, so plan how you will get to Boscastle before you set off.

Arlington Court is a neoclassical country house, built in the 1820s and set in a picturesque garden. Inside, you can see the Chichester family's antique furniture and an eclectic collection of family memorabilia. The National Trust Carriage Museum on site holds an impressive collection of horse-drawn vehicles.

Tip: Dogs on leads can go in the garden, wider estate and Carriage Museum, but not the main house or tea-room. Follow the brown signs, not sat nav, as unmarked lanes are dead ends.

King Arthur's Great Halls stand on Fore Street in Tintagel and are dedicated entirely to the legend of King Arthur. The building opened in 1933 and was built by Frederick Thomas Glasscock as the headquarters of the Fellowship of the Knights of the Round Table of King Arthur. Fifty-three different types of Cornish stone were used in its construction.

Tip: You enter through the King Arthur themed shop at the front, so head straight through it to reach the halls and windows.
