Smugglers' Caves
Highlight • Cave
Due to its proximity to mainland Europe and its remote, cave-riddled bays, smuggling was a livelihood and a vital economic activity for many people along the Kent coast throughout much of the 18th and 19th centuries.
Thanet's smugglers openly carried weapons, defied the authorities, and forced locals to supply them with fodder and fresh horses. During the Battle of Botany Bay, informed tax collectors clashed with the notorious smuggler Joss Snelling and his gang. Machetes, knives, and boat hooks were used in the bloody battle, in which Snelling lost 15 of his men.
The danger (or the contraband) must have suited Snelling well. He reached the ripe old age of 96 and in 1830 – at the age of 89 – was fined 100 pounds for smuggling – an enormous sum!

Was this a place of worship, a site of secret meetings, or an extravagant gimmick? We don't know who built this amazing place or why, but ever since the first paying visitors descended the chalk staircase in 1838, the grotto's origins have been hotly debated.

Tips from the Community
When the later Queen Victoria visited Broadstairs, Snelling was so notorious that he was introduced to her as “The Famous Smuggler”! The cave entrance is easily accessible in the rear curve of the rock face and goes slightly uphill. There are a total of 3 smaller caves, lined up like a string of pearls. There used to be an upper exit that no longer exists. The way there is also the way back. Between the individual caves are low passages. If you don’t mind a bit of dust and lime, it’s fun to go on a discovery tour.

There are more questions than answers… The underground Shell Grotto, discovered by chance in 1835, captivates visitors with its curved chalk walls covered in 4.6 million shells. They form a magical mosaic of strange patterns and symbols. Was this a place of worship, a site of secret meetings, or an extravagant gimmick? We don't know who built this amazing place or why, but ever since the first paying visitors descended the chalk staircase in 1838, the grotto's origins have been hotly debated. https://www.shellgrotto.co.uk/visit

Guided tours by volunteers at the National Trust through these WWII tunnels/bunker. 125 steps down, approx 90 minute tour, only £6. Very factual, learn about the troops who used it, the reason it’s there, and how it was built.

£6 for an hour’s tour by the National Trust. Well worth it! Go 125 steps underground and tour the tunnels from WWII

Given its proximity to Hever Castle – the birthplace of Anne Boleyn – you can imagine Henry VIII riding through this holloway as you walk through it. An eery, magical and beautiful sight
