Edinburgh’s Old Tunnels: Train Routes, Servants’ Work and Island Guns
A railway tunnel became a footpath. A house tour follows a servants’ passage. On Inchcolm, a tunnel helped crews reach their guns. Here is what each route was built to do.
Based on published records and visitor information. We have not visited these places.

From train tunnel to footpath
People walk through Rodney Street Tunnel on a route opened for trains in 1842. It now forms part of Warriston Walkway, linking King George V Park with paths in north Edinburgh.
The council’s September 2026 roads list confirms it as a public footway. Check signs for temporary closures: the list does not tell us the condition of the lights or surface today. Nearby Scotland Street Tunnel is a separate passage with different access.
Other passages served households, canal boats and military crews. At Newhailes, a named house tour includes a servants’ tunnel. On Inchcolm, an island tunnel helped crews reach their guns. Their different uses explain why an entrance alone tells you little about what lies beyond it.

A place to stop a boat
At Ratho Basin, boats could leave the main canal to stop or enter a dry dock. This was a space that could be closed off and drained, allowing workers to repair the parts of a boat normally below water. Scottish Canals still lists moorings and visitor services at the basin.
Farther west, the Falkirk Wheel’s original boat tour goes through Roughcastle Tunnel. A trip brings together a boat lift and a tunnel journey. Book the listed sailing and follow the crew’s advice.
The public areas do not open every part of either site. At Ratho, do not board boats or enter the dock without permission. The Roughcastle boat trip is not a walking route through the tunnel.

The work behind the grand rooms
At Newhailes, servants used a passage as part of their work around the house. The sources identify a service route, with no evidence here of a secret escape tunnel.
One National Trust for Scotland self-guided tour takes visitors through the main rooms and kitchen, then out through the passage. It shows two sides of life in the same house.
The named tour has been listed for the last Sunday of the month. It includes stairs. Check the event dates and ticket details. Entry to the estate alone does not promise entry to the tunnel.

A route to the island guns
Inchcolm is known for its abbey, but it also had military defences. The island’s military history describes a tunnel through the hill that helped crews reach their guns quickly.
Historic Environment Scotland offers island visits. We have not found current confirmation that visitors can enter the military tunnel. Check the ferry and site details, then ask staff which areas are open.
At Cramond, gun and searchlight sites served a barrier built to stop ships. The concrete remains make more sense as parts of that defence.

Check the tide before crossing
Cramond Island looks close to shore. The causeway is safe to walk only during the right tide window. Check current safe-crossing times and weather. Leave enough time to get back. Seeing someone else walk out does not prove you can return safely.
If the tide cuts you off, do not wade back. In an emergency, the RNLI says to call 999 and ask for the Coastguard. Getting onto the island does not give the right to enter its military structures.
Plan these as separate trips, using each place’s public route or named tour. Rodney Street offers a walk along an old railway. The Newhailes tour follows a servants’ route through a house. Neither tells you which passages are open on the islands.
