Dunhams Wood Light Railway

You'll find this little railway tucked away east of March, a working narrow-gauge line that's genuinely easy to miss if you don't know where you're looking. Dunhams Wood Light Railway is the sort of place that appeals to a very specific crowd - enthusiasts of heritage railways and anyone with young children who still get excited about steam trains will absolutely be in their element here.

The line itself is modest compared to some of the grander railway attractions dotted across England, but that's rather the point. You get the authentic feel of a proper working railway without the queues or the gift shop overkill. Most visits run to around an hour or so, which is about right - any longer and you've probably exhausted what's on offer. The actual operational details are a bit vague online, so you'll want to ring ahead or check their website before making the trip, as opening hours and whether they're running on any given day can be hit or miss.

If you're based at one of the caravan parks nearby - Fenland Camping is closest at just over three miles away - it makes for a decent half-day activity. It won't anchor your entire holiday, but combined with a walk around the Cambridgeshire countryside, you've got a solid afternoon. Worth a visit if railways are your thing; perhaps give it a miss if you're hoping for a major spectacle.
