We were happy with this campsite! It's conveniently located between Grand Teton National Park and Yellowstone National Park. The environment is peaceful and surrounded by nature. The cabins are clean and equipped with beds (you need to bring your own sleeping bags), a table, chairs, and a lamp. However, please note that there is no electricity. Each cottage has a fireplace and a picnic table with chairs. The shared showers and toilets are available 24 hours a day, free, clean, with hot water always available. Additionally, there is a drinkable water refill station. Adjacent to the campsite, there's a restaurant that opens at 7 o'clock in the morning, providing a convenient option for dining before a long day of hiking. Very friendly and helpful staff in the reception, which is open 24/7.

Basic cabin with a bed and small table. Larger windows for more airflow would have been nice when hot but overall it was great.
