Kailash Tekri is a small hilltop Shiva shrine near town, best treated as a quiet add-on rather than a destination in its own right. The appeal is simple: a short rise, a temple, and a view over Ambaji's low buildings toward the surrounding hills.
It works best around sunset, when the light softens and the day's heat starts to lift. If you are short on time, choose Gabbar Hill first; Kailash Tekri is for travelers staying long enough to fill out the local circuit.
