Trou aux Cerfs, a dormant volcanic crater in Curepipe, Mauritius, offers panoramic island views and is easily accessible by car, taxi, or bus. It's free to visit and can be enjoyed solo, though it's often a stop on guided island tours. While open year-round, clearer weather provides the best photographic opportunities, avoiding the foggier or rainier periods, especially from November to April. A typical visit lasts 15-30 minutes, perfect for capturing photos and admiring the scenery. Expect local vendors selling souvenirs and snacks at this popular viewpoint.
