Plan a visit
By car:
You can access our museum by car and if using a satnav device, please use the address: Heritage Way, Priddy's Hard, Gosport PO12 4LE.
Waterbus:
A Waterbus from the Historic Dockyard runs regularly to the museum. A full timetable can be found here.
The waterbus operates between 10am to 4pm daily during Summer, unless weather or other operational restrictions apply. During Winter, the waterbus operates under a restricted service, weekends only and subject to weather or other operational restriction.
The Waterbus is, unfortunately, unable to accommodate wheelchairs, due to the unsuitability of the jetty and steps.
A suitable wheelchair can be pre-arranged to meet the waterbus on arrival in Gosport. Please ask a member of staff for details or email enquiries@nmrn.org.uk to confirm availability
Please note that your safety is our number one priority and the sea is subject to change. Due to this, the waterbus may not be running. In the unlikely event, the waterbus stops running when visiting one of our Gosport sites from Portsmouth Historic Dockyard, you will need to arrange alternative travel back. This can be on the Gosport Ferry, which is larger than the waterbus so can operate in rougher conditions, or arrange a taxi from a local company. The National Museum of the Royal Navy will not be able to reimburse you for alternative travel arrangements.
Walking:
You are able to walk between our two Gosport sites. Please note however that this is a 2-mile walk and will take roughly 40 minutes.
We welcome all visitors to the Dockyard and we have tried to make it as safe as possible. However, some of our attractions are historic buildings and ships, and we know that there can be challenges for some visitors.
For those who believe they will be limited in their visit or need extra support, we do offer access restriction discounts, free carer tickets, and on-site additional support.
At Explosion Museum of Naval Firepower, you are able to leave your buggy at reception. Please note that your buggy and any items left in the buggy are left at your own discretion and we take no responsibility for anything lost or stolen.
Accessible toilets are available to guests at the museum
Free WiFi is available to our visitors. You will need to sign in and agree to terms and conditions.
