The trail is a wide path of volcanic stones interspersed with some larger rocks that have probably fallen from above. The trails have guard rails provided by fencing, as you can see in the picture. The grade is fairly steep and constant. It will take a moderately conditioned person about 20 minutes to walk to the refreshment stand at the summit where guides can be hired (or will be waiting for tour groups). Many in our group took more than 30 minutes to arrive at the summit.
Passing through clouds or fog is frequent in spring. We made the trip in May, and we passed through dense layer.
