What Travellers Say
Reviews Summary
Visitors consistently praise the breathtaking and overwhelming views of Onami-ike Crater Lake, calling it a must-see natural wonder. The hike, while steep and rocky, is considered rewarding and manageable for a half-day trip. Some note the lack of facilities and limited parking as minor inconveniences.
"Great view. If you only want to walk around the crater, it’s an easy walk with a mostly flat trail. (But you do need to hike a little to get the crater first though.). I’m here in a winter day so it was covered in snow. It’s cold but worth the view. (It’s not that dangerous but please still be cautious and stay safe on the trail?"

"What a nice trail on the beautiful sunny day! The walking way up to the hat was not difficult but just steep and rocky. It would be great if you have the trekking pole. It may be slippery if it rains. The hat was clean, spacious, and great to have a read about the Onami lake. There is no toilet here, but only the private space. You need a handy disposable toilet. The view is just breathtaking, worth walking on the rocky way."
