Mammoth Hot Springs Hotel Unable to Open for the Winter 2022/23 Season

Guests with winter reservations at Mammoth Hot Springs Hotel will be contacted. You will find the National Park Service news release here once it is posted 

As you’re likely aware, extreme flooding in June impacted certain roadways in the park. Those repairs have been made in impressive fashion and the roads have since reopened. As well, a new wastewater treatment system is being built to serve the Mammoth area and reopen the Mammoth Hotel. However, the new temporary system is not ready to support hotel operations on the timeline originally envisioned. The National Park Service is working diligently to make this system operational as soon as possible, but we have been advised by the National Park Service that we will be unable to open the Mammoth Hotel to overnight guests or provide food services in the Mammoth Hot Springs area for the winter season, December 2022 through March 2023. You will find the National Park Service news release here once it is posted.

The gift shop, ski shop, barista and lobby will be open to serve guests. Regularly scheduled snowcoach service between Mammoth and Old Faithful, as well as our regular tours from Mammoth, will be available.

As an unfortunate result of this closure, all room and package reservations for the Mammoth Hotel will be cancelled. This includes room and package reservations that include stays at Mammoth Hotel only (Frosty Fun at Mammoth, Winter Wolf Discovery), and package reservations that include Mammoth Hotel and Snow Lodge (Winter Couples and Old Faithful Winter Expedition). We will cancel these reservations and process refunds of your deposits; therefore, no further action from you is required. Please allow 7 to 10 business days for the refund to be processed. Please note, there are still opportunities to rebook your winter visit at the Old Faithful Snow Lodge. Details are provided below.

For those guests with non-package room reservations that include both Mammoth Hotel and Old Faithful Snow Lodge OR Mammoth Hotel rooms with Mammoth-based tours or snowcoaches, the Mammoth Hotel lodging portion of your reservation will be cancelled, and that portion of your deposit refunded. We will keep the Old Faithful arrangements and other tour/snowcoach portions intact. If you wish to cancel the Old Faithful or other tour/transportation components as well, we will gladly refund the full deposit for those portions of any winter reservation with at least 14 days advance notice prior to scheduled arrival. You can cancel online, contact us via web chat, our contact form, or by calling our call center at 307-344-7311.

We recognize the significant impact on your travel plans and thank you for understanding this unfortunate and unanticipated situation.

The situation is not impacting the Old Faithful area or other locations in the park. We will be in full operation at the Old Faithful Snow Lodge, with lodging, food, tours, gift shop, and skier services available as usual. As there is still winter availability at the Snow Lodge, you might consider replacing your Mammoth room or package reservation with a stay at the Snow Lodge. For example, our Frosty Fun package at Snow Lodge offers some discounts on rooms and transportation, along with a Snow Card gift card that entitles you to 10% off meals, tours, and gift items. If you’re interested in this option, please book online or contact our reservations call center at 307.344.7311. Please be advised that call volumes may be very high resulting in long hold times. As a reminder, access to Old Faithful Snow Lodge in the winter is limited to over-snow travel, and there is snowcoach service from Mammoth from the north and Flagg Ranch from the south.

Gateway Community Options

Gardiner, Montana is located at the north entrance to Yellowstone, five miles north of Mammoth Hot Springs. If you wish to replace your Mammoth Hotel reservations with Gardiner lodging, dining, and more, you can find information on those options from the Gardiner Chamber of Commerce. For Mammoth guests who rebook in Gardiner, Montana, we’re working on a schedule that will provide the airport shuttles to Gardiner and transportation from Gardiner to Mammoth for access to our tours. While details are still being finalized, we ask that you check the website occasionally for the latest information. Silver Gate and Cooke City, Montana are located just east of the Northeast entrance to Yellowstone and also provide winter lodging, dining and other wonderful winter recreation experiences. From the south, snowcoach service is offered by Scenic Safaris between Flagg Ranch and Old Faithful. Lodging available south of the park can be found by contacting the Jackson Hole Chamber of Commerce.


As Covid-19 transmission rates have been unpredictable, and high rates could necessitate a return to mask mandate with little notice, we suggest you check our health and safety page frequently prior to your scheduled trip. You can find more information on our health and safety protocols here.

Mask requirements vary by park, based on CDC’s COVID-19 Community Level tool. Please check the park website before visiting. Additional details are available at

A short section of road in Lamar Canyon will remain a paved, single lane through the winter season. A temporary stop light will be in place for traffic control and delays will be minimal. For the most up-to-date information about temporary road closures in the park, visit the park roads web page.
