Waterstone Retreat

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.

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.

Camel Creek is a family adventure park near Wadebridge in North Cornwall. The mix includes thrill rides and rollercoasters, outdoor play areas and animal areas, so there is plenty to fill a day. Its indoor play space covers 45,000 square feet, which means a wet day need not spoil the plan.

Tip: Check the park's website before you go for current tickets and events, as offers change. If a free return pass is offered with day tickets, read the terms first: it is non-transferable and excludes Toddler Takeover days, birthday parties, group bookings and school visits.

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.

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.

Lanhydrock is a Victorian family home inside a Jacobean mansion, once lived in by the Agar-Robartes family. Most of the interiors were rebuilt after a fire in 1881. Inside, you can see the Long Gallery with its ornate ceiling, and families can play in the refurbished Victorian nursery.

Tip: It is busiest between 11am and 2pm, so arrive later in the day for a quieter visit and shorter queues for the house.

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.
