Definitely worth it! Husband and I went on the 45 min tour on a particularly cold November evening. But it was worth it! It was about 50° so bundle up. We weren’t but bought a spiked hot cider and that helped. We sat on the top, open air area. They do have an enclosed warm area downstairs with the concession stand and bathrooms. Additionally, Alison, our guide, was amazing and offered so much valuable information. If we had more time, we would have booked a longer tour.
