Lake Hayes, near Arrowtown, Otago, is a picturesque destination in New Zealand, renowned for its mirror-like reflections of the surrounding mountains, especially during calm weather. It's generally accessible, offering a relatively flat walking/cycling trail around the lake, suitable for most fitness levels. The lake is great to visit year-round, although autumn provides stunning foliage colors. A visit can be enjoyed independently, with the loop track well-marked, but guided tours offering deeper insights into the region's history and ecology are available. The cost is primarily for transportation and potentially bike rentals or guided tours. Expect to spend approximately 2-3 hours to complete the loop around the lake.
