Travel By Air: The nearest airport is New Delhi. From Delhi one can reach Almora by train or by road as given below.
By Train: The nearest train station is Kathgodam. Several important rail stations in India have direct connection to Kathgodam. From Delhi, there three main trains run almost daily from Delhi to Kathgodam: 12040 ANVT-KGM Shatabdi (06:15 AM), 15013 Ranikhet Express (22:40) and 15035 UTR-SAMPARK Express (16:00). We recommend the first two connections. One may also get down at Haldwani (the station just before Kathgodam). Please note that train number 12040 starts from ANAND VIHAR railway station at Delhi and the other two trains depart from OLD DELHI railway station. So, if you plan to reach Kathgodam by train, after arriving at the airport or New Delhi railway station, you should direct yourself towards the Anand Vihar railway terminus or the Old Delhi rail station in Delhi. The metro stops most nearest to these rail stations are Anand Vihar and Chandni Chowk respectively. Details about Delhi metro service's are available here.
