The library is open Tuesday to Sunday from 10:00 to 22:00, and closed on Mondays (except statutory holidays).

If you fail to cancel a reservation in time, accumulating more than 3 no-shows will result in a 90-day reservation restriction, so please plan accordingly.

What to Expect

The library's unique cave-like design creates a distinctive atmosphere for reading and relaxation. However, to preserve the environment, certain items are prohibited: food, colored or sugary drinks, pets, study materials, personal books, and photography equipment such as cameras, selfie sticks, and tripods. Backpacks must be stored in lockers before entering. Note that the library does not offer book lending or sales services.

One of the highlights is the sunset view from the library. At dusk, the sky turns orange-red with golden-edged clouds, offering about 40 minutes of changing colors—a free natural exhibition that's worth experiencing.

Getting There

Public transport: take bus routes 57 or 49 and get off at Waitan Center station. If driving, you can park at the Century Park parking lot.

From the Bell Tower, taxi is recommended; from nearby dining spots like Xiamen Xiamian, you can choose to cycle or take a taxi.

You can also take the free elevator on the west side of Century Bridge to go up the bridge. Facing the sea in front of the library, walk along the coastline to the right to reach the bridge entrance.

For a scenic approach, consider the 'Hainan Star' cruise, which passes by the library and other landmarks, or the 'Meilan No.1' night cruise that offers views of the library's exterior. The 'Bengbeng Bus' also operates daily from 19:30 to 20:00 in August, connecting various landmarks including the library.
