Things to do in Inveraray when it rains

Check the day before deciding that rain means a museum visit. The castle closes on Tuesdays and Wednesdays and has a seasonal closure. The jail also lists reduced opening days, so confirm its live booking calendar before relying on it. On an operating day, either can provide enough interest to anchor the outing without inventing a long list of indoor places. At the jail, allow time for the courtroom and prison stories. The full circuit includes stairs and short transfers between buildings, so a waterproof and an access check still matter. Wheelchair visitors can see ground-floor prison areas, but that is a different route from the whole experience. The separate escape room needs its own booking and should not be assumed to come with ordinary entry. The castle offers ground-floor rooms and further floors reached by stairs, with a video alternative for rooms that cannot be accessed. Confirm the arrangement before travel. Garden time is optional in rain, and the gravel approach may be less comfortable than a central paved street. Keep lunch and any second stop flexible. Auchindrain is an open-air museum and Dùn na Cuaiche a woodland climb, so neither should be sold as a way to stay dry. For a shorter wet-weather visit, choose one suitable indoor attraction and a meal, then return without forcing an exposed waterfront walk.
