Two days is enough to see the major highlights of Glasgow, but you will barely scratch the surface of Scotland's largest and most vibrant city. With 48 hours, you can dedicate Day 1 to the West End, visiting the stunning Kelvingrove Art Gallery and Museum and wandering the campus of the University of Glasgow. Day 2 can be spent in the City Center and East End, exploring the Glasgow Cathedral, the Necropolis, and the modern Riverside Museum on the Clyde. Glasgow is famous for its "friendly" locals and incredible live music scene, so two nights allows you to experience the nightlife in the Merchant City or Finnieston areas. However, if you want to use Glasgow as a base for day trips to Loch Lomond or the Isle of Arran, or if you want to properly explore the "Mackintosh Trail" (the works of architect Charles Rennie Mackintosh), you would ideally need 3 to 4 days.
