If you love to explore the rugged coastline of the UK, then you'll definitely want to stop off to see the Old Battery & New Battery at The Needles on the Isle of Wight.
These are Victorian coastal defence and secret rocket testing sites, sitting high above the Needles Rocks.
You may need to pay to enter the actual batteries, but you can enter the mini exhibit with everything you need to know about this site, for free!
Why not plan a lovely day out to the coast with the family? This is the perfect free stop-off.
Concessions: Free entry
