Are Gardens your thing?
The Japanese Garden at Cowden in Fife is a bit different and has recently been re-opened following extensive works. Open from April onwards
Here is a link to a The Gardens in Scotland website you might want to use to research further. Many private gardens are open through Scotland’s Gardens, but you will need to check when the owners are due to open them. Some gardens will open for you by appointment, given advance notice. There are great gardens at Branklyn in Perth, Cluny in Aberfeldy (you might see a Red Squirrel), at Scone and Falkland Palaces and at most of our historic houses.
