Located only 24 kilometers from the Indo-China (Tibet) border, Badrinath is generally a one dayjourney from either Kedarnath, the site that precedes it in the Char Dham circuit, or one of the main disembarkation points on the plains. The temple and its surrounding village are accessible by road. The best time to visit Badrinath is between June and September.

 
How to reach Badrinath[edit]Latest comment: 9 years ago1 comment1 person in discussion
Air[edit]
The nearest airport is the Jolly Grant Airport near Dehradun 317 km (197 mi) away by road. However, the distance by a helicopter journey is hardly 100 km. There are many providers of helicopter service from Dehradun and Phata.
Railway[edit]
The nearest railway stations are at Rishikesh (at 297 km) and Kotdwara (at 327 km). However, Rishikesh is a small railway station not connected by fast trains. Kotdwara is connected by only a few trains. Haridwar railway junction, 24 km farther from Rishikesh, has train connections to most of the major cities in India and is, therefore, the railhead for Badrinath.
Road[edit]
Badrinath is reached by national highway NH58 that connects Delhi with Mana Pass in Uttarakhand near Indo-Tibet border. Buses carry pilgrims from New Delhi to Badrinath via Haridwar and Rishikesh in pilgrim season of summer months. Rishikesh is the major starting point for road journey to Badrinath. 
Regular buses operate from Rishikesh bus station to Badrinath and start very early before dawn. The last bus from Rishikesh leaves for Badrinath before dawn. The road is narrow after Joshimath and travel is not permitted on the road after sunset. Therefore if one misses the bus for Badrinath at Rishikesh bus station, one has to go only up to Rudraprayag, Chamoli or Joshimath and spend the night there to take the early morning bus for Badrinath from that town.
The road distance from Rishikesh to Badrinath is 293 km (182 mi) via Rudraprayag, Chamoli and Joshimath.
