The best beach for sun-bathing. Surrounded about 8000 pine trees and waves are calm even feel like a lake. On 3,6km long beach, you can find your spot to chill out. Also it is a shallow beach so suitable for children. Beside beach, I recommend you to visit Kasamatsu park for "bridge to heaven" view which literally what Amanohashidate means in Japanese.
The best beach for stroll. Before get to the beach, walk up to a lookout point which is also known as Onaru-Kofun-gun(Onaru burial mound, it is an ancient burial mound from 6th-7th century, the time Tango region was "Tango Kingdom" and that time the Kingdom played important role to contacting with Eurasia continent), you can see beautifully naturally carved rocks. After enjoyed the view, take a stairs down to the beach. On the beach, you can see a huge rock it is called Tateiwa which has Jizo statue inside the rock.
3. Kotohikihama beach
The best beach for having a fun? The beach is known as a singing sand, if the sand is wet, it cannot work..... If you still want to hear the sound when it's raining, you can visit the museum by the beach. Also on the beach, there is a tiny open-air Onsen(hot spring) for free of charge, it is not separated by sex so must wear swimsuit. Have a nice relax time by the sea!
4. Kamai beach area
The best beach area for sea-kayaking. Please check another page of my blog for further info. http://seasidekyoto.blogspot.com/2017/02/sea-kayaking-in-kumihamafrom-april-to.html
We are not located in tropical area but the colour of the sea is stunning! All the sea-kayaking tour start from early morning(8:30) so no public transportation is running so please stay over night at Furan-no-yakata where is the meeting point of the tours.
There are too many places I don't want to miss out from travel route but I know I cannot include all...so this is the four significant beaches which I highly recommend! (There are more beaches available in Tango region, please look at "Swimming-sea" category from my blog.) There are certain reasons of why I started from 1 to 4, so I don't recommend changing the visiting order.
Travel model route focused on beach hopping(so please consider this for April to November, if you want to swim July to September(September can be too late, depends on each year)) and include must see sightseeing spots in Tango region!
