The fantastic thing about Glasgow is that it is a long narrow city , with a motorway running through the middle. It means that wherever you are, you are never far from the countryside.
So for example, you can live on the Southside of Glasgow, like me in Pollokshields, and still only be 20 minutes from the countryside to the North (and less to the South) and just over half an hour from Loch Lomond.
Glasgow also has a great suburban railway system and a dinky wee underground.
In addition to Bearsden, Milngavie, Newton Mearns and Giffnock, have a look at Pollokshields (one of the world's original garden suburbs, yet within a long walking distance of the city centre), Shawlands, Newlands, Langside and Strathbungo on the Southside and the West End on the North side (depending on your budget
) within the city boundary. There are good schools within Glasgow - ds has just finished at Shawlands Academy (and now away at Aberdeen Uni) and I couldn't be more impressed with the school (which, BTW, is recognised by the British Council as an "international school" the most international state school in the UK? with 55 languages spoken at the school
and c50% with English as an Additional Language).
Lots of parks in Glasgow as well as excellent free museums like Kelvingrove Museum (although you have to pay for the Science Museum). Plenty of culture with Scottish Opera, Scottish Ballet and the RSNO all based in the city.
