• Trinity Hot Springs is a historic hot spring resort in Central Idaho
• The mineral water earned European Natural Health Water Certificate
Trinity Hot Springs is a developed rustic resort near the small community of Featherville about 100 miles away from Boise. The hot spring resort, previously known as Paradise Hot Springs, sits in the wooded hills at the hot mineral Grouse Creek near the South Fork of the Boise River. This beautiful geothermal oasis offers a perfect escape from the day-to-day routine to the nature of rural Idaho and provides a variety of services as well as access to numerous recreational activities.
Water comes out of the source located two miles underground at about 135°F and flows into a large outdoor swimming pool. The pool temperature depends on seasons and weather conditions and varies from 95 to 108°F in the summer and from 90 to 95°F in the winter. Natural spring water contains a wide range of beneficial minerals with a high concentration of silica and fluoride. This water is pure and free of contaminants and certified to be safe for drinking.
Trinity Hot Springs is the only North American location that earned Natural Health Water Certificate (Naturliches Heilwasser) from the Institute Fresenius based in Germany. This certification proves the exceptional purity of this geothermal mineral water. The Trinity drinkable natural water as well as its infused flavored varieties are available at the resort or can be purchased online.
In addition to refreshing soaking, resort guests can enjoy spa services, yoga, and meditation classes. Lodging options include six lodge rooms, two cabins, a separate house, and a campsite for both tents and RVs. Trinity Hot Springs is open year-round. You can rent the club facility for your family reunions, birthdays, and other events. The pool is open for overnight guests as well as for day visitors.
The resort is family-friendly, pet-friendly, and handicap accessible. Bathing suits are required on property and no glass containers are allowed. This is a membership-based resort so at least one member in a group has to have a membership for both overnight stay and day use.
