I will come to Qingdao Airport at 11:30pm and layover 13hrs to next day flight at 1pm.

Hi, Lu Xun Park, Botanical Garden, Naval Museum and Zhongshan Park are popular attractions in the city. Have a nice trip!

Can you tell me what transport from Qingdao airport to Lu Xun Park, Botanical Garden, Naval Museum and Zhongshan Park?

You are suggested to follow this route: Naval Museum - Lu Xun Park - Zhongshan Park - Botanical Garden.
From the airport, you can take shuttle bus line 2 to the Main Railway Station, go southwards along Tancheng Road to take bus 26, 223, or 501 to Lu Xun Park. Visit the nearby Naval Museum first and then go across the road to stroll around Lu Xun Park.
Take bus no. 312 in front of Lu Xun Park for 2 stops to Zhongshan Park. After that, walk eastwards to Botanical Garden.

Thanks
