Free entry, but parking is £3 if you use the official one. Free if you park across the road. Very informative and well laid out museum.

Atop the escarpment of Portsdown Hill above Portsmouth lie five forts. Built during the Victorian era, these forts provided vital defence for the military harbour below. Fort Nelson is a six-sided Palmerston Fort, squat with red brick walls. After falling out of use, the fort was eventually sold to the local council to be renovated and reopened as a museum. Today, the fort houses a fascinating array of cannons and other weapons, with live firing demonstrations and guided tours. You can also explore the tunnels within but don't forget a jumper because they can get rather chilly, so thick are the walls.

Nice to take a break inside the castle and enjoy a coffee from the little cafe just inside the entrance.

The path is away from the road, but it can be a bit narrow for walkers and bikes together. There is often a good wind coming in from the sea. There are several seats along the path and it's worth stopping to take in the view.
