Set off from Blackburn
Via A96/AWPR to the A90, then down through Perth. Leaving by around 9am gives you a buffer for a coffee/fuel stop (Perth or Dundee way is a natural halfway point) and still gets you into Riverside's car park for opening.
Riverside Museum
Start here — the tall ship Glenlee is moored right outside. ~1.5 hrs.
Kelvingrove Museum
Red-sandstone galleries — Dalí, natural history, a Spitfire hanging overhead. ~1.5 hrs.
University of Glasgow
Wander the quad and cloisters. ~20–30 min. Car's still back at Kelvingrove, no need to move it.
Kibble Palace & Botanic Gardens
Glasshouses stay open latest of the day — a calm way to close things out.
Argyll Hotel, Dunoon
Settle in for the night — back here again tomorrow after the Waverley cruise. Worth confirming guest parking when you book; if not, there's pay & display nearby on Alexandra Parade.
Dunoon Castle, Castle Gardens & Castle House Museum
The castle itself is long gone, but the hilltop grounds have grand views over the Clyde to Gourock, and the wee museum next door is packed with local & Highland Mary history. Round it off with a wander along the Esplanade seafront back towards the pier — about 10–15 min on foot. ~1.5–2 hrs all in.
PS Waverley — Paddle Steamer Cruise
The world's last seagoing paddle steamer, out on the Firth of Clyde for the afternoon. Grab lunch on the front before boarding — worth being at the pier ~20–30 min early.
Argyll Hotel, Dunoon
Second night here — set off back towards Glasgow tomorrow morning.
Head back to Glasgow
Western Ferries to Gourock (~20–25 min crossing) plus the drive in — allow ~1–1.5 hrs door to door.
Burrell Collection & Pollok Park
On the way in from Gourock — museum plus a stroll to spot the Highland cattle. ~2 hrs.
Barras Market
Weekend-only, and still comfortably open at this time. ~45 min.
Glasgow Cathedral
Opens later on Sundays — this timing lines up well. ~45 min. Right by the car park.
Glasgow Necropolis
Right next door — closes 4:30pm so don't linger too long, but great late-afternoon views over the city. ~45 min.
Sharmanka Kinetic Theatre
Book via ticketsource.co.uk/sharmanka once you have a firm date — the showtime should anchor this end of the evening. Afterwards it's an 18–20 min walk back up to the car at Cathedral Precinct, or a quick taxi if legs are tired by then.
