By air: Very well connected with some major airports in India, including New Delhi, the closest airport is Leh Airport. To reach the destination from the airport, taxis can be hired.
By Rail: At a distance of 812 km from Leh, the closest major railway station from Leh is Jammu Tawi. To reach Leh over Srinagar Leh Highway in a 3-day journey with overnight halts at Srinagar and Kargil, taxis can be hired from the railway station.
From Leh via Manali Leh Highway, Joginder Nagar railway station is just 635 KM but is not a major one.
By road: The most feasible option is to travel the distance between gurudwara and Leh by road. Between November and April, the road remains closed, so during that time, you should avoid going there.
