11 Best Activities In Dover
Dover's best wet-weather cover was dug, not built. The Fan Bay Deep Shelter and The Wartime Tunnels at Dover Castle both sit in the adventure listings and both keep you under chalk rather than under umbrellas, while Dover Castle itself is flagged for indoor and outdoor visiting, so it works either way.
Eight of the town's eleven listings have space under a roof in all. For the fair days, Dover Sea Safari — the highest-rated thing in town at 4.9 — and Samphire Hoe Beach make the coastal case.

Few seaside towns are this well defended against rain. Start with the castle and its tunnels, keep Gamebase or Playbase in reserve for smaller children, and save the sea safari for a clear sky.
Visiting Dover with kids: FAQs
What should we do in Dover on a wet day?
You are spoilt: eight of the eleven listings here have indoor space. The Fan Bay Deep Shelter and The Wartime Tunnels at Dover Castle are rated 4.9 and 4.6 and stay dry by design, the Dover Transport Museum suits vehicle-mad children, and Gamebase and Playbase cover the younger ones.
Is anything in Dover free to visit?
Playbase is the one listing our data supports calling free to enter, and it is an indoor venue aimed at younger children, which makes it a useful card to hold. Beyond that, the honest answer is to confirm details with each venue directly — what our records are strongest on is which of Dover's eleven attractions keep you under cover.
Does Dover Castle work with children in bad weather?
Dover Castle carries both flags in our listings, and The Wartime Tunnels at Dover Castle appear separately under adventure, entirely under cover. That combination means the site can flex with the sky: ramparts and grounds while it stays dry, tunnels when it does not.
