Mammoth Hot Springs Hotel 2023 Update

May 15, 2023

At this time, the NPS repair work appears to be on schedule to allow a June 16 hotel reopening. However, NPS still has several key components of the ongoing water treatment system repair and testing process to complete over the next several weeks for the system to be deemed operational. Though we still hope to reopen the Mammoth Hotel on June 16 and do not want to cancel reservations prematurely, the opening date for Mammoth Hotel remains subject to change, and we may not have a definitive answer for another couple weeks.

All other properties are opening as scheduled, and you may consider booking alternate accommodations if the Mammoth Hotel is unable to open on June 16. Please be advised that we have limited availability elsewhere inside Yellowstone National Park during the early season.

As always, thank you for your understanding.

Changes to Early Season Services

Mammoth Hot Springs Hotel 2023 Opening Delayed

Guests with summer reservations at Mammoth Hot Springs Hotel will be contacted. You will find the National Park Service news release here.

April 28, 2023

Wastewater Treatment System Construction Ongoing

In June 2022 the Yellowstone region experienced unprecedented flooding. The flood damaged the Mammoth Hot Springs wastewater treatment system, which led to the ongoing closure of Mammoth Hotel. Though originally scheduled to reopen on April 28, 2023, the National Park Service (“NPS”) advised us recently that construction delays related to the Mammoth wastewater treatment system have prolonged the closure, and we cannot open rooms or restaurant food services in April as originally planned.  You can find the National Park Service update here.

Currently, there is no scheduled reopening date, but NPS has confirmed that the Mammoth Hotel will not open before Friday, June 16, 2023. As a result, we have no choice but to cancel all reservations with Mammoth Hotel during this time.

Additionally, all tours departing from the Mammoth Hotel will be cancelled until the hotel reopens. These tour reservations will be cancelled automatically, and a refund will be issued for your deposits. Please allow 7 to 10 business days for the refund to be processed; no further action from you is required. However, if you wish to rebook into other tours, you can find tour information here.

Mammoth Hotel will remain open for day use in the interim, including the gift shop with take-out pre-packaged food and snack items and coffee service in the Map Room. No other food service will be available at Mammoth Hotel.

For guests with room reservations at Mammoth Hot Springs Hotel alone, or that include both Mammoth Hotel and other in-park property(s) before June 16, 2023, the Mammoth Hotel lodging portion of your reservation will be cancelled and that portion of your deposit refunded. All other portions of your lodging reservation will remain intact. If you wish to cancel any of these other reservations as well that have been affected by the Mammoth Hotel closure, we will gladly refund the full deposit for those portions of any summer reservation with at least 7 days advance notice prior to scheduled arrival.

We recognize the significant impact on your travel plans, and we thank you for your understanding of this unfortunate and unanticipated situation. Because we are unable to open Mammoth Hotel at this time, NPS authorized us to open rooms at Old Faithful Inn and Canyon Lodge earlier than previously scheduled in order to provide alternative overnight accommodations, though not in the Mammoth Hot Springs area of the park.

• We will open select rooms at Canyon Lodge on May 5 (instead of May 19) with no other lodging and limited services available until May 19
• We will open additional select cabins at Lake Lodge on June 2 (instead of June 10) for displaced Mammoth Hotel guests only. Food service and gift shop will be available at the nearby Lake Yellowstone Hotel
• All other properties will open as scheduled, but please note that there is limited availability if you choose to select other options
• Please refer to our Alerts webpage for further details on accessing lodging and the limited available services at the Old Faithful Inn and Canyon Lodge during the early openings

EARLY SEASON SERVICES FOR RELOCATED GUESTS

To accommodate relocated guests from Mammoth Hotel, we are opening up the Old Faithful Inn East wing a week early,  the Canyon Lodge two weeks early, and Lake Lodge eight days early. For guests who have relocated to any of these properties, please note the following:

For guests with room reservations that arrive after June 15 through the end of Mammoth’s operating season (November 26) your reservations will remain intact. We will send a hotel status update at least one month prior to your arrival date. If we know we are not able to open the hotel during your scheduled stay, you’ll have the option to either rebook at any other in-park property based on available space, or cancel and receive a full refund. You can also cancel your reservations now and receive a full refund.

If your room reservations include both Mammoth Hotel and other in-park property(s) you can cancel any of these other reservations as well and we will gladly refund the full deposit for those portions of any summer reservation with at least seven days advance notice prior to scheduled arrival.

For all guests planning to visit Yellowstone this summer, we also suggest you regularly check the Yellowstone National Park Plan Your Visit webpage.

If you’re not able to find in-park relocation options, Gardiner, Montana, is located 5 miles north of Mammoth Hot Springs and offers a variety of lodging and dining options. Silver Gate and Cooke City, Montana, are located just outside the Northeast entrance to the park. You can also find additional gateway community lodging information by clicking on the following links for Cody, WY, (East entrance); Jackson, WY (South entrance); and West Yellowstone, MT (West entrance.)

Thank you for your patience as we respond to events that are out of our control.
