The last I heard they are open . Here is a quote from another thread from Ranger Lon
”Email permit requests are being processed remotely while the Visitor Center is closed. If you send a permit request to our email addresses (indicated on the top of the forms) I am processing them from home and sending back approved copies.
If you fax a request form, it will be picked up from the office when possible and processed, but not as quickly as the emailed requests.
Hopefully, when everything finally blows over, we can return to normal operation and hit the ground running. Until then please be safe, and be aware of local and State restrictions that may change whether these activities are advisable.”
