Overall totally worth the money! Be ready to spend about 2 hours if you want to walk through all three tracks (Walks 1, 2, and 3)—the scenery with the colorful pools and Champagne Pool is completely surreal. Important tip for Lady Knox Geyser: You have to arrive early and make sure you are there before 10:15 AM (it only erupts once per day, so don't miss it!). Give yourself plenty of time to drive over from the main park entrance to the geyser viewing area. Highly recommend adding this to your North Island itinerary!
