How to reach Nainital
Nainital sits in the Kumaon hills of eastern Uttarakhand, and the single most important thing to understand about reaching it is that the town has no railway station and no airport of its own — the mountains do not allow either. You travel to a gateway in the foothills or on the plains, and finish the journey by road, climbing roughly 1,000 metres over the final stretch on a winding mountain highway. Build that last leg into your plans: the map distance from the railhead is short, but the drive up the ghat road takes far longer than flat-country intuition suggests.
By train. The nearest railhead is Kathgodam, about 34 kilometres away on the edge of Haldwani, where the broad-gauge line from the plains meets the foot of the hills and simply stops — it is the last station before the mountains. Kathgodam is well connected to Delhi and to other cities, with overnight and daytime services that make it the standard arrival point for rail travellers. From the station, shared taxis, private cabs and buses run up to Nainital in roughly an hour to an hour and a half depending on traffic on the ghat. Haldwani, a little below Kathgodam, is a larger town with more services and is an alternative disembarkation point. Because live timetables and seat availability change constantly, check current trains and fares in the search box on this page rather than relying on a fixed schedule, and note that seats on the popular hill-gateway trains fill early in the summer season.
By road. For many visitors the whole trip is done by road. Nainital is roughly 300 kilometres from Delhi, a drive of about seven to eight hours via the well-used Delhi–Moradabad–Rampur–Haldwani corridor, with the final climb from Kathgodam to Tallital being the slow, scenic part. Government and private buses run from Delhi's Anand Vihar terminal and from other North Indian cities to Haldwani, Kathgodam and, in season, directly to Nainital's Tallital bus stand. Self-drive and hired car-with-driver are both popular; a driver who knows the ghat road is worth the money if you are not used to mountain driving. Note that during the peak season and on holiday weekends the town authorities sometimes regulate or cap vehicle entry to control congestion around the lake, so confirm current rules before driving all the way in.
By air. The nearest airport is Pantnagar (PGH), about 65–70 kilometres away in the plains of Udham Singh Nagar district. It is a small airport with a limited and changeable roster of domestic flights, so you cannot count on convenient connections through it; when flights are operating, the onward drive to Nainital takes roughly two to two and a half hours. For most travellers the more reliable air gateway is Delhi (DEL), from where you continue by train to Kathgodam or by road. Always confirm current Pantnagar routes before planning around them, and treat Delhi as the dependable fallback.
Getting around once you arrive. Nainital itself is compact and best explored on foot — the flat Mall between Mallital and Tallital is a pleasant walk, and stretches of it are pedestrianised or closed to traffic at busy hours. For the outlying viewpoints (Snow View, Tiffin Top, Naina Peak, Land's End) you can walk the forest trails, hire a pony, or take a shared or private taxi; a fixed-route local taxi and taxi-union stand operates for the standard sightseeing circuit, and agreeing the fare or hiring a car for the day is the simplest way to string the high points together. The aerial ropeway offers a quick, popular alternative to the climb up to Snow View. Parking near the lake is tight in season, so many visitors leave the car at their hotel and use taxis and their own feet.
