Three historic tunnels you can visit, in three different ways

A former railway tunnel in Edinburgh is a public walkway. At Standedge and Roughcastle, visitors go underground on organised boat trips. The difference starts with who runs each route.

Based on published records and visitor information. We have not visited these places.

The tunnel is only part of the answer

Rodney Street Tunnel in Edinburgh has become a public footway. Standedge in Yorkshire takes visitors under the Pennines by boat. Near Falkirk, a booked trip passes through Roughcastle Tunnel after riding the Falkirk Wheel. All three routes go underground, but the way in depends on what each tunnel does today.

Rodney Street belonged to a railway. Standedge carries the Huddersfield Narrow Canal beneath the hills. Roughcastle is part of the canal connection at the Wheel. Their history explains why they were built; the council and waterway operators explain how visitors can experience them now.

Edinburgh: a railway passage that became a walkway

Edinburgh Council traces the railway through Rodney Street Tunnel to a line laid in 1842. The line has gone, but this short passage has found another purpose. The council’s September 2026 roads register includes the tunnel under Rodney Street in Warriston Walkway, an adopted public footway. It links into the old railway path and King George V Park.

That makes Rodney Street a place you can pass through on the recognised public route, without arranging a tour. The register does not promise that the lights or surface will be in a particular condition when you arrive, so follow any temporary signs. Scotland Street Tunnel is a separate railway tunnel nearby. The public status of Rodney Street does not extend to it.

Standedge: choose the boat trip you mean to take

At Marsden in Yorkshire, the stone entrance to Standedge Canal Tunnel is the visible end of a much longer journey under the hills. Canal & River Trust runs visitor boat trips into the tunnel. Its advertised Discovery rides and less frequent through trips are different experiences. A booking for one does not mean you will travel the full length, so check the exact trip before paying.

The visitor centre can also be reached along the canalside path from Marsden. The Trust warns that this approach may be slippery in wet or icy weather. It says the boat is accessible for a wheelchair user from the canal side, but has space for only one wheelchair on each trip. If that matters to you, contact the operator before choosing a sailing. The nearby railway tunnels are separate working routes, not an extension of the canal visit.

Roughcastle: part of a journey on the Falkirk Wheel

Scottish Canals advertises an original Falkirk Wheel boat tour that lifts passengers between canal levels, travels through Roughcastle Tunnel and returns. Roughcastle is therefore one part of a booked boat trip. The heritage point on our map is not a boarding place, and the advertised trip does not establish a public walking route through the tunnel.

The names can be confusing. Roughcastle Tunnel is not the older Falkirk Tunnel on the Union Canal. Check that the booking page names the trip you want. Scottish Canals has also published temporary works around a south-bank path at the Wheel in autumn 2026, while saying that navigation is not expected to stop. Check its current notice and follow signs on arrival rather than assuming a past route through the grounds is unchanged.

Choose the route before setting out

These are three separate outings, not stages of one walk. Rodney Street needs a check for any local closure on a public footway. Standedge needs a look at the particular boat trip and boarding needs. Roughcastle needs a place on the Falkirk Wheel’s advertised tour. Each operator’s page is linked below the relevant place record.

None of those arrangements gives permission to enter another tunnel, railway line or service passage. If a route is not advertised for visitors, leave it out of your plan. There is enough to see from the lawful paths and booked boats without guessing where an unmarked opening might lead.
