Description

Fort Nelson is a beautifully preserved Victorian fort and a museum category attraction situated on Portsdown Hill. It is widely considered one of the best things to do with kids in Portsmouth because it combines sprawling outdoor ramparts with a massive collection of historic cannons and big guns. As home to the Royal Armouries' national collection of artillery, it offers a hands-on look at military history in a safe, open-air environment.

Visiting this historic landmark is incredibly budget-friendly for families. General admission is free for both adults and children, though you must pre-book your arrival slot online to guarantee entry. There are occasionally small charges for specific seasonal events or car parking, but the core museum experience is accessible to everyone.

If you are looking for the best place for a day out with family and kids that offers plenty of space to run around and explore, this is it. It provides an educational day out where children can walk through underground tunnels, see world-famous weapons, and enjoy panoramic views over the harbour. It is a fantastic choice for parents seeking a high-quality historical experience without a high price tag.

Top 5 Highlights

The Underground Tunnels: These are a highlight because they feel like a real adventure. Kids love exploring the cool, dark passages that lead to the various parts of the fort.
The Parade Ground: This is a great spot because it’s a massive open space where kids can let off steam. From here, you can see the scale of the Victorian engineering that built the fort.
The Mallet’s Mortar: Look for this giant weapon—it’s one of the largest ever built. It’s a must-see because it helps children understand just how "big" big guns can get.
The Viewpoint: Head to the top of the ramparts. It’s a highlight for parents and kids alike because you get a perfect view of the modern Royal Navy ships in the harbour below.

Facilities

Toilets: Located in the visitor centre and near the café, including baby changing facilities.
Buggy Parking: While the visitor centre is accessible, the tunnels and ramparts have steep steps and uneven ground; a carrier is recommended for the darker corners.
Food & Drink: The 1871 Café serves hot drinks, sandwiches, and "soldier-themed" lunch boxes for kids.

Pro-Tips for Parents

Bring a Torch: While the tunnels are lit, kids love bringing their own small torches to explore the darker corners of the fort.
Pre-book Early: Even though it is free, weekend slots for the best things to do with kids in Portsmouth fill up fast.
Wrap Up Warm: The fort is very high up and can be incredibly windy, even on sunny days. Bring an extra layer!
