Tottori Sand Dunes GPX Route - Tottori Prefecture, Japan
The Tottori Sand Dunes are a great spot if you're looking for a long GPX route to walk for hours. There are lots of Pokestops and Gyms located on the route itself, so you should have no issue staying stocked up on Pokeballs and other supplies. The long distance of this route is perfect for hatching eggs; being able to almost squeeze in two 10km eggs in one lap (when used in Super Incubators).
