Thoughts & Reflections

What did you like the most about the trip?

① Local guided trekking in the Tottori Sand Dunes

“Compared to visiting the Sand Dunes on my own without a guide, the experience was completely different. I felt that the knowledge explained by the guide about the Sand Dunes made me experience and appreciate the natural surroundings in a different way.”

② San’in Kaigan Geopark Museum of the Earth and Sea

“Although the building itself is not large, I felt that this museum is a MUST when visiting the geopark area. Here, you can learn about the the geopark’s natural aspects through a variety of materials such as original videos and giant squid exhibitions.”

Why would you recommend this tour to other people and who would you recommend it to?

“The geopark itself has an academic theme of being a place that is rich in various topography, geology, climate, and people’s lives in relation to the formation of the Sea of Japan.”

“Other than that, various activities are available around the Tottori Sand Dunes and the Uradome Coast so I think I could recommend this tour to groups of students in the inbound field as well.”

“Many of the student groups I’ve previously handled are those who are studying Japanese or are interested in Japan. Which is why I think it could be a valuable experience for them to study this area which is geographically and geologically important for Japan.”

What is the best season for joining this tour?

“According to local guides and taxi drivers, a lot of people come to visit the sand dunes in the summer for some reason. In the summer, traffic jams are unavoidable so it is probably best to avoid that season.”

“I visited and trekked through the sand dunes in October and the weather was neither too hot or too cold. It was quite comfortable and the sky was a beautiful shade of blue.”

“However, if putting activities that are affected by the winds and waves into consideration, it is probably better to visit in the summer.”
