Updates Regarding COVIID-19

We have been actively taking precautions to provide a healthy and safe environment for our guests, visitors, employees, and locals for several weeks now. With regularly scheduled anti-viral cleaning of highly touched spaces, social distancing, allowing employees to stay home if feeling ill or uncomfortable, and cancelling reservations for guests without question has allowed us to have seemingly stay on the right side of the curve. All our employees and patrons appear to be happy and healthy.

We had already planned on shutting down operations by the end of the week, but an official decision has been made to close all hotels and vacation rentals indefinitely starting Sunday March 22, 2020. In response to this decision we will not be accepting bookings for any dates prior to May 15th. As always, we deeply appreciate you all for your continued support of Grassy Flats and we hope to see you soon. For more information regarding COVID-19 and the city of marathon please visit,
