The Deep is a public aquarium in Hull, overlooking the Humber Estuary where the River Hull meets it. Its Endless Ocean tank holds sharks, rays and northern Europe's only pair of green sawfish, and you can walk through Europe's deepest viewing tunnel or ride a glass lift through the water.

Tip: Check the daily talk times when you arrive and plan your visit around the shark and penguin talks. Use HU1 4DP or HU9 1TU for sat nav, which takes you to Tower Street.

Beverley Minster is the parish church of Saint John and Saint Martin in Beverley, East Riding of Yorkshire. It is one of the largest parish churches in the UK, bigger than a third of English cathedrals, and is regarded as a Gothic masterpiece.

Tip: Tours, including the Roof Tour, can be booked through the Minster's website. On Sunday mornings access is limited to the west end until services finish.

The Ferens is one of the UK's finest art collections, housed in a Grade II listed building in Queen Victoria Square. The collection runs from late medieval painting through to sculpture and new media, with highlights from Lorenzetti, Frans Hals, Canaletto, Leighton, Stanley Spencer, Helen Chadwick and Gillian Wearing. Alongside the permanent displays there are changing exhibitions.

Tip: No need to book for a normal visit, but last admission is 30 minutes before closing and the café shuts an hour before the gallery.

Bolingbroke Castle is a ruined castle in Old Bolingbroke, Lincolnshire. It was founded in 1220 by Ranulf, Earl of Chester, shortly after he returned from the Fifth Crusade. It is one of the earliest castles designed and built without a keep, relying instead on thick walls, five D-shaped towers and a twin-towered gatehouse.

Tip: Look for the lower walls and the ground floors of the towers, which are the main surviving parts to see.

Tattershall Castle is a National Trust property built in the 15th century by Ralph Cromwell, Treasurer of England. The Great Tower is an imposing red-brick keep with seven storeys, including the Parlour, Great Hall, Audience Chamber and Private Chamber. Some of the huge medieval fireplaces were once ripped out for sale abroad before being tracked down and returned.

Tip: The tower has 149 steps and no lift, and the grounds have deep gravel, so wear sensible shoes. Dogs on leads can go in most places but not inside the Great Tower, except assistance dogs.

The Trolleybus Museum at Sandtoft sits on part of a former wartime RAF station in Lincolnshire. It was founded in 1969 to house and restore trolleybuses as they disappeared from Britain's streets, and its collection is now described as the largest of preserved trolleybuses in the world, with well over 50 vehicles.

Tip: The museum only opens on selected days, so check the Open Days calendar on its website before you travel.
