Stargazing in Lake Tekapo is special because it sits inside a Dark Sky Reserve, so on a clear night, you can see the Milky Way with your naked eye. Free option: walk a little away from town lights, give your eyes time to adjust, and you’ll still get an incredible show. Paid option: book a guided stargazing tour or the Mt John Observatory experience for telescope views and expert explanations. Either way, dress very warm and aim for a clear, low-moon night. Tekapo gets cold fast after dark.
