Use the overlap of official hours
HR&CE publishes 6:00 AM–noon and 4:30–7:45 PM. The district Tamil page gives 7:30 AM–noon and 4:00–7:30 PM. Plan within 7:30–noon or 4:30–7:30 and confirm locally rather than choosing the more convenient margin.
A vehicle road is not step-free access
The district reports separate ascent and descent steps plus a vehicle road. Ask about the final surface, thresholds, handrails, seating and toilet before travel. A meaningful ground-shrine visit may be the better plan for limited stamina.
Secure the return
App taxis are unreliable. Agree an auto fare, waiting time and return before leaving Alathur Gate or the village. Carry water, avoid the hill in lightning or midday heat and keep the Tamil name செட்டிக்குளம் offline.
