First, the parking lot is free, which is a big plus. The park itself isn't that big, so there's no need to pay for parking. The air-raid shelter within the park is one-way and a bit far away, so it takes over half an hour to walk back and forth. It mainly features educational programs on air defense, air defense, and air defense, along with photo displays. The park's museum is free, while the adjacent Aerospace Museum costs an additional 90 yuan. Also, good news: if you buy a ticket to the Two Bombs City, you get a free ticket to Qiqu Mountain. You can exchange your ticket directly at the Qiqu Mountain front desk with your online purchase record, and pay an additional 20 yuan for round-trip transportation. Qiqu Mountain is primarily a tourist attraction, the Qiqu Mountain Temple, where people burn incense. No wonder it's free; it's incredibly difficult to visit, especially in the heat.
