Hi!
It will be around a 40-minute walk from the airport to the park, so I definitely don’t recommend walking.
The cheapest option to get to Sakuranoyama Park from Narita International Airport:
- Walk from Narita International Airport to Narita Airport Terminal 1 (around 650m)
- Take the bus heading to Museum of Aeronautical Sciences and Narita. In Japanese, it will be written as “多古本線：航空科学博物館～成田”
- Get off at Sakuranoyama bus stop, in Japanese, it will be written as “さくらの山”.
- Walk about 200m to the park.
