Coastal Hiking at Miura

I recently joined a volunteer and hiking group by the name of Jambo. The organization focuses on environmental protection and also supports programs in Africa, hence the name jambo  – ‘hello’ in Swahili. They are a great group of people, old and young, Japanese and non-Japanese, and all with a love of the outdoors and meeting people!
Please check out their homepage:


We arrived at Arazaki in Miura, about 50km south of Tokyo, mid-morning. The weather was perfect: sunny, breezy, and warm. After a briefing by the group leader, we headed for the coastline. The area is noted for its stunning cliff faces. From a distance, though, it wasn’t the rocks that first caught my eye, but the mass of tents! Families with little kids and big kids alike were camping along the cliffs, BBQ’ing, playing in the water, having a great time! What a great way to spend time with family and friends.

The closer we got to the sea shore, the more extraordinary the rocks became. At a quick glance, the cliffs look messy and dirty, but in fact years and years of wind erosion, water erosion, and faults and folds in the earth have resulted in incredible patterns and carvings. Geologists must go crazy here! The colours in the rocks range from light cream to brown to black. It reminded me of hardened lava pipes. I was so curious that after some research, I discovered it is in fact alternating beds of silt, basaltic gravel, solidified ash and volcanic sand. Could Mt Fuji have been responsible for this??!

Another thing that surprised me was the water… crystal clear, sparkly, cool, refreshing! I could see every little detail on the sea bed, from the tiny fish nibbling on rocks to the bumps on the back of the shells. Although well into spring, it was still a bit too cold to jump in. Perhaps another trip in the summer!?

Well, enough of me describing, take a look yourself…
