Cream O’Galloway. Every Day.
Beach at Moss Yard, Kockbex and Sandgreen are all ace and worth visits, with varying sand or rockpooling.
Glentrool has walks and biking aplenty, a lovely spot.
Clatteringshaws visitors centre, climb the wee hill behind, head down the raiders road (dirt track) and picknic by the river.
Galloway Sailing centre hires canoes, sailing boats etc. A great, great spot (and happy memories of student summer jobs with the to-be mrs_oab for me…)
Some nice local gardens (Glenluce IIRC) have palm trees etc.
A day out visiting all sorts down Isle of Whithorn – it really is a place that feels like you need to just sloooooooow down. Bookshops, cafe’s, nice beaches, random gardens/artists/potteries all down the way, Whithorn itself is also nice for a mooch.
Some nice small hills to walk – get out OS map and follow nose. Ben John, Cairnharrow etc are nice (and great for Adder spotting).
Kirkcudbright, Gatehouse and Castle Douglas are all lovely. The road from Kirkcudbright round to Brighouse and along the coast to Knockbrex is worth exploring – loads of bays, walks and lovelyness. BIG crabs to be found in one of them…
