Parking - there is on-road parking around the model yacht pond and along the harbour arm. Note that these are disc zones with your stay limited to three hours in some places.

Bus - the Castle is a 10-minute walk from the bus terminus (all routes except 111)

Access - We regret that the Castle is not accessible to wheelchairs beyond the shop. The Castle has steps, steep staircases and uneven surfaces which those with restricted mobility or impaired vision might find difficult. There are sheer drops and children should be closely supervised at all times. We recommend that visitors with special needs visit the Disabled Go page on Castle Cornet, which gives a detailed description of access - click to be directed to the page here

What you can do at Castle Cornet

The Noon-day gun is one of most popular and impressive sites. It is fired daily throughout the season by keepers clad in scarlet costumes who will stay and pose for photos with you after every firing. 

Guided tours of the outer areas of the castle run daily at 10:30am. 

There are children's trails to follow around the castle and activity sheets in some of the museums which you can get from the castle shop. Just ask in the shop or look out for our staff in uniform around the site. 

Every day from April to September there are Living History presentations from the Guernsey History in Action Company. They last about 20-30 minutes and start most days at 12.10pm (subject to change and occasional cancellation on the day) so check at the shop when you arrive. You can visit their website at to learn more about them and see their timetable of performances.  

Garden Tours of the period gardens take place fortnightly in June, July and August when the gardens are at their best. Call the castle to find out the timetable.

The Castle refectory is open every day throughout the season for coffees, light lunches, snacks and ice creams and as it is fully licensed, you may also enjoy a nice glass of wine with your food.

The Gift shop is beautifully stocked and sells a wide variety of souvenirs, local crafts, prints, fudges and local and historic books. If nothing else, we recommend you buy a guide book of the castle.

Within the ancient walls of the Castle are five museums to be visited at your leisure.

Is there anything for children & families?

 Castles are already exciting but we do provide extra resources for little ones and their grown ups:

  • Trails and activity sheets for all ages  
  • Dressing up room at the base of the clock tower
  • Spot-it picture boards inside the galleries, aimed at children under 7
  • Baby change facilities next to the 201 Squadron Museum
  • Back carriers can be borrowed from the shop - pushchairs may be left there on arrival
  • Suitable picnic spots include the lawn in the Inner Ward
  • Café and toilet facilities in the Castle are located in the Upper Barracks building

How long does it take to see everything?

A familiar question the staff are asked every day but for which we have no answer. Everyone is different and enjoys historic sites and tourist attractions in their own way but we rarely see disappointment however long you come for. 

You can...

Come for an hour - Have a quick peek in the museums, enjoy the fantastic views of the harbour and St Peter Port, purchase a guide book to swat up on your history and a magnet for your fridge and away you go. Happy you're done.


Come all day - Go on the tour, watch the gun fire and the living history show, bring a picnic and snooze on the lawns, inspect every herb in the gardens and every Roman pot and medal in the museum, watch the boats out on the harbour over a slice of cake in the café and follow the kids on every trail.

Just enjoy - however you like to do it.
