You may have heard some spooky rumours about Mt. Fuji's Aokigahara Jukai forest but there are many nice trekking routes in this thick forest. The trekking is very flat and easy to walk and you will be immersed in breathtaking scenery. The area is also known for hundreds of small icy caves, which are a great way to escape the summer heat. Bring a headlight for a mini-caving adventure!
Finish the trekking at Saiko lake, one of Fuji's famous five lakes. The lake has amazing views of Mt. Fuji and the water is crystal clear that makes you wanna take a quick dip.
