The Carrick coast is unusually dense with things to see. Within the town you have an island bird sanctuary reached by boat, a Georgian jail and a Victorian museum. Within twenty minutes: Robert Adam's greatest castle, the lighthouse built where Robert the Bruce was born, a ruined abbey and a road where cars appear to roll uphill. Within an hour: Burns' cottage, the UK's first Dark Sky Park, a sub-tropical garden and the southernmost tip of Scotland.
Each page below gives you what it is, why to go, exactly how far, how long to allow and what is nearby.
If you only do three things
Culzean Castle for the house and the country park; Ailsa Craig by boat from the harbour if the weather allows; and the free walk across the links from Maidens to Turnberry lighthouse at golden hour. Between them they cover the castle, the island and the coast.
A note on seasons and access
A great deal here is seasonal. Castle interiors, gardens, lighthouses and forest drives generally run from around Easter to late October, and several close entirely from November — Culzean's castle, Souter Johnnie's, the Mull of Galloway and Logan among them. The country parks, the free ruins and the coast stay open all year.
Two specific things to check before travelling: Crossraguel Abbey, which opens April to September only and Thursday to Sunday only, and been restricted by Historic Environment Scotland masonry works, and the Quay Zone, where the soft play and cafe were still to reopen after storm repairs.
