We visited Ah-Shi-Sle-Pah as a side trip to Bisti Widerness. Ah-Shi-Sle-Pah receives even less visitors than Bisti. We hiked entire day but saw no one. Rock formations are amazing. The place is worth exploring a couple days. GPS is needed; otherwise you can easily get lost especially if you hike in the dark as we did.
