Main access pattern for most pilgrims
Chengannur remains the most widely used rail approach point for Sabarimala-bound devotees; the Chengannur-Pamba rail link was found infeasible, so the Chengannur KSRTC hub remains the primary rail-to-bus connection.
From Chengannur, Pathanamthitta, and nearby gateways, pilgrims usually continue toward Nilakkal and Pamba through official bus movement.
Pamba is the ordinary base for the final climb to Sannidhanam. If you take the traditional forest route, the practical road approach changes and is usually aligned around Erumeli.
Parking restrictions, shuttle movement, opening dates, weather, and crowd controls can change. Official notices in force on the day of travel are final.
