Last week I went to Old Westbury Gardens to see their Shimmering Solstice holiday light display. The display is a self guided walking tour through the mansion’s grounds. The tickets are timed entry but you can go at your own pace once you are in. There are a few concessions where you can buy snacks and warm beverages. There is also a table selling Christmas light necklaces for kids. We spent about an hour walking along and then went to get ice cream. If you are interested in visiting yourself you can learn more here.
