The small car park is level tarmac with no accessible spaces marked.

Approach to site

The site is along a short, slightly sloping path. There are 41 steps to King George’s Battery (the first 14 with no handrail).

Visitor centre

The shop and artefact display are in the Governor’s House. The doorway has a threshold.


The castle site is very large, steep and rocky. All areas are reached via a number of narrow stairways, many of them historic.

Governor’s House (shop and artefact display) is up the first set of stairs at the entrance to the site at King George’s Battery.

The Spur, Spanish and Bower Batteries are on a long, loose gravel path with several steps along the south west wall. The path finishes in a dead end.

The Guard House (exhibition on the castle’s history) and Portcullis Arch are reached via a very long, steep, narrow and historic set of stairs between the two rock peaks of the site.

The White Tower’s remains are further still, at the top of the site’s highest point. This is reached via another very long, narrow set of stairs. It can be very windy along this exposed route. 

The French prison, Wallace Tower, and One Gun and Duke of York’s Batteries are along a slightly sloping loose gravel path, which begins at the top of the stairs just after the Portcullis Arch.

The Duke of Argyll’s and Prince Regent’s Batteries are up another set of steep steps from just after the Portcullis Arch. A steep, loose gravel path leads to the powder magazine at the top of the second peak.


Nearest adapted toilet is about 1/3 mile away at:
