Dock Koi

Dock Koi is exactly what it says on the tin - a specialist aquarium in Cleethorpes dedicated entirely to koi fish and their care. You'll walk through tanks displaying these ornamental carp in various sizes, colours and patterns, learning about breeding, water quality and pond maintenance along the way. It's educational without being preachy, and genuinely interesting if you're into fish or thinking about keeping koi yourself.

The space is compact - you're looking at maybe 45 minutes to an hour if you're thorough, less if you're just passing through. Children who like fish will find it engaging; those after splashing about and sea creatures might find it a bit specialised. Adults with garden ponds get the most out of it, honestly. The staff know their stuff and will answer questions properly rather than just pointing at tanks.

Admission details aren't published online, so ring ahead on the number listed. Opening hours are a bit variable - closed Wednesdays, shut at 3pm on Tuesdays and Fridays. If you're staying at Haven Cleethorpes Beach Holiday Park just down the road, it makes a sensible rainy-day stop or a quiet alternative to the seafront crowds. Don't expect the scale of a major aquarium chain, but that's rather the point. It's specialist, local, and refreshingly unpretentious.
