Tips for Taiwan Travelers

Best time to visit

January and February are cooler, so it is recommended to bring a warm jacket and scarf; March and April are more comfortable during the day, suitable for photography and outdoor trips.

Ticketing and Queuing Tips

Hot meals and peripherals are always at risk of being sold out, so it is recommended to purchase puzzle props and redeem special editions when entering the park, and then follow the route to raid the meals and photo spots. If it is a weekend or a continuous holiday, you can save a lot of queuing time by making good use of the park's opening slot.
