moderate
Approximately 17–18 days
Moderate—able to manage early-morning hill viewpoints, short walks (1–3 hours) at altitude and light beach activity; not technical endurance required.
Start in the stately avenues of Kolkata, climb tea-scented ridges in Darjeeling and Gangtok, then trade mountain air for coral-clear water at Havelock and Neil Island. This 18-day private tour pairs colonial history and Buddhist monasteries with snorkeling and island time.
The first light on Kolkata’s Hooghly River gilds the white stone of the Victoria Memorial, steam rising from a chai stall as vendors wheel out braided jute baskets. You begin here — in a city where British-era fortresses rub shoulders with Bengali cafes — and end with coral reefs and powder-white sand that make you forget the subcontinental bustle. This is an itinerary that threads urban history, mountain mornings and tropical seas into a single journey.

Pack a lightweight down or fleece for early mornings at Tiger Hill and Tsomgo Lake—temperatures can drop suddenly above 2,400–3,700 m.
Inter-island ferries (to Neil and Havelock) fill quickly—reserve seats and allow extra time for transfers to the jetty.
Use biodegradable sunscreen and a rash guard for snorkeling to protect coral and reduce skin irritation.
International travelers must carry passports; suppliers will collect passport info for bookings and permits—keep copies stowed separately.
The route traces colonial-era governance (Fort William, Cellular Jail) and British tea estate development in the Darjeeling hills, alongside centuries-old Tibetan Buddhist traditions in Sikkim and Kalimpong.
Coral reefs in the Andamans are sensitive—use reef-friendly sunscreen, avoid touching coral and follow guides’ instructions to minimize impact.
Warm layer for pre-dawn views at Tiger Hill and chilly evenings in Sikkim.
