The sign outside the Manresa Grotto states simply: "A beautiful grotto exists." And it's true! It does exist, and while it's beautiful in its own way, it can be a little eerie when one visits alone on a rainy day.
Despite the potential for gloom, this is a nice little picnic spot and rest area along the LeClerc Road just north of Usk, located within the Kalispel Indian Reservation. The grotto is a natural cave that served as a chapel for Jesuit missionaries and the Kalispel people beginning in the 1840s.
The trail to the grotto switchbacks up the hillside and is very short; no more than a half-mile round trip. In some places wooden hand railings have fallen down, so visitors with small children would need to keep a close eye on little hikers. Otherwise, consider this a super short, super easy hike to visit the cave!
