  • Back from the March was closed due to a typhoon last August, could not visit and tour once again became available. Longquan cave is famous underground lakes also increases transparency, beauty continued as before, is no other cave is the bright blue of the Blue Dragon. But in the area along the river and on the road during construction there are many, and there are many know of the damage, could imagine at the time.

  • Like becoming a resume from 3/19 and tried it in a rental car from Morioka! Who was 84 km on the mountain road to drive so much pain as well as passengers who were sleeping! It is a large limestone cave. That's not about 10 degrees take care! While no toilet!

  • Currently for damage by a flood closed ryusendo went in the family. Personally, I'm about 40 years ago, memories, far away again visited. As June and low temperatures also visited with long memories of the old cave tour in quite a hurry, left after good walk a little more slowly and regretted. Cold weather protection is required. I think cave is very impressive because it is one of Japan's three great limestone caves, visit a little more slowly. And unfortunately not see 3/19 in the flood of visitors after the are concerned about recovery. 3. 11 disaster, would you want come to visit after recovery is followed by last year's floods and natural disasters.

  • Cave was good but at places where water would drip they had a lot of plastic sheets to keep you dry but I thought they were a huge eye sore. Very nice area around cave as well. Make it part of a road trip and it is worth the drive.
  • This place is very interesting. The cave is large, with a few separate levels. Many small spaces and lots of stairs, but manageable. The cave is lit with many color changing lights that creating a good atmosphere. There are a couple small cafes and a restaurant on the property as well.
  • Cave is very cool and has great history. Signs with proper routes will keep you from getting lost. Just make sure to bring a hoodie, you will get wet!
  • While open until 6pm, come earlier so that you dont miss out on walking around the outside of the caves, and trying some local made frozen yoghurt. the caves themselves are well worth viewing... english information as well as korean everywhere. The water is amazingly clear, and you can drink some of it coming straught out of the spring. PH9.5 and safe to drink.
  • Beautiful area! Loved the caves but it was also a pretty area to walk through. The grape and strawberry ice cream was good too!
