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 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!
