How to split wine, surf and forest without rushing any of it.
Day one: arrive, settle in, and keep it easy with two or three cellar doors around Wilyabrup before an early dinner. Day two is the big one — start at Boranup Forest before the day heats up, then Mammoth Cave, then a late-afternoon surf check at Gnarabup if conditions allow.
Day three is for whatever got missed — usually another winery or two, plus the drive back via Busselton if the jetty and its underwater observatory are of interest. Three nights is comfortable; two is doable but rushed.
