Came by and a sign was posted saying it was closed for safety reasons.. website and answering machine says open- no snow at all today or within the last week-sunny and clear skies

I would definitely say they are closed if it has snow and ice on the roads. It is a very narrow road.

If there was snow on the road they will close. Its a narrow road to the top with a good 1000 foot climb in altitude.

Very narrow road. Difficult to navigate under the best conditions. I visit the park in the summer.

Last time i went there, about a year ago, it was no rail guards on the road to the top; is dangeros but also beautiful; i'll sugest to visit this place on summer time.

I was just there on 2/18/2018. We drove up and walked the crater.

Wet and icy conditions are a possible reason. Narrow roads.

I was there in July with my kids and we were not able to walk all the way up due to common since and Ice cycles forming on my eyelids..Enjoy your adventure.Heed any warnings.

Double check the website.

Well, obviously something happened.
