Castles near Glasgow
21 castles are within 40 miles of Glasgow - fewer than Edinburgh's count, and the city's own castle didn't survive, but Bothwell and Crookston are both a short trip out and genuinely worth it.

Can you reach any castle within 40 miles of Glasgow by train?
11 of the 23 sit within 1.5 miles of a railway station, the closest being Aberdour Castle and Gardens (Aberdour, 0.1 miles), Alloa Tower (Alloa, 0.4 miles), Stirling Castle (Stirling, 0.4 miles) and Newark Castle (Port Glasgow, 0.5 miles). Those are straight-line distances from the station to the castle, so the walk on the ground is longer than the figure.
Can you go inside every castle within 40 miles of Glasgow?
Not all of them on the same terms. 8 of the 23 restrict what a visitor can see. Crossbasket Castle is a hotel, so there is no way in without booking a room or a table. At Cadzow Castle, Craignethan Castle, Clackmannan Tower and Drummond Castle the building itself isn't open to visitors, so you see it from the grounds or from outside. At Menstrie Castle, Portencross Castle and Lauriston Castle you get the grounds or a booked tour rather than free run of the building.
