Sunnyland is a modern amusement park on the slopes of Trebevic, above Sarajevo. Its headline ride is the alpine coaster, but the broader appeal is the combination of family entertainment and quick access to the mountain that frames the city.
It is not essential Sarajevo, but it is useful if you are travelling with children or want a light break after museums and war-history sites. The views are part of the point, so pick a clear afternoon and combine it with a wider Trebevic outing if transport allows.
