Hot Springs Fed Pool and Hot Tub

welcome to Lost Trail

Where It’s FUN to Get In HOT WATER!

Our main attraction is our beautiful, chemical-free, hot springs pool. The natural, mineral, hot springs bubble up from the ground at 107° year round. Our swimming pool average water temperature is 95° and 103(winter)-105°(summer) for the hot tub.
Sacajawea Lodge, Meriwether Lewis Lodge and Cabin occupancy includes access to the pool, hot tub & dry sauna as well as one pool towel per day. Our daily rate is discounted by $1 for those staying in our RV Park and Campground. Keep in mind this is also the bathhouse, with changing rooms and showers. There is only a rustic outhouse (and port-a-pot in the summer) available in the camping area.

Our Features

Why Choose Us

Everyone in the family will relish a refreshing dip, regardless of age. The pool is perfect for exercising, young children, the elderly, and women with “baby on board” – all of which are groups of people that need to avoid the hotter temperatures of the hot tub. For the ultimate in relaxation, follow your swim with a session in our dry sauna or 8 person hot tub. The 20′ by 70′ pool has a 9’ deep area diminishing to a 10” wading pool. It is covered by a dome in the colder months, throughout most of Fall, Winter and Spring. The giant greenhouse-looking dome keeps the pool usable year-round by keeping the water warm as well as by keeping the air warm around the water.
