India.

India is 3.3 million square kilometers stretching from the Himalayas to the tropics. Three things to internalize:

1) The plains are unlivable in summer; the Himalayas are unreachable in winter. Late March through mid-June, Delhi, Agra, Jaipur, and most of Rajasthan hit 40–46°C. Outdoor sightseeing becomes a sunrise-and-sunset operation. Meanwhile Ladakh's two road approaches (Manali–Leh and Srinagar–Leh) are buried under snow until late May, Kashmir's high passes are closed, and Spiti Valley is unreachable. Summer is a vertical migration season, go up or grit through the heat.

2) Monsoon is regional, not national. The southwest monsoon arrives in Kerala around June 1, sweeps north over six weeks, lingers until September. Mumbai gets pummeled (June rainfall 500–600mm, serious flooding most years). Kerala gets steady, dramatic rain, the traditional Ayurveda season. Goa shuts down for tourism. The Golden Triangle is hot, humid, and gray. Ladakh sits in the rain shadow and is dry and accessible July–August. Pick your region.

3) Festivals are pricing events, not just cultural ones. Holi (March 3, 2026), hotels in Mathura, Vrindavan, Pushkar, and Jaipur run 2–3x normal rates and book up 3–4 months ahead. Diwali (November 6–11, 2026), five days of national domestic travel, flights triple. Pushkar Camel Fair (November 1–9, 2026), hotels book 6 months ahead at 3–5x rates.

The payoff is real: India is one of the highest-value travel destinations on Earth, with backpacker $25–40/day and mid-range $60–120/day in 2026. The friction is the timing puzzle. Solve that and the rest is gravy.

India splits into five travel zones, each with its own seasonal logic.

The Golden Triangle and Rajasthan (Delhi, Agra, Jaipur, Udaipur, Jodhpur, Jaisalmer). Best mid-November through February, with December and January as peak, Delhi 7–22°C, Jaipur 10–25°C, dry, clear, comfortable. Avoid May, June, and most of July, heat is genuinely dangerous (>45°C is normal in Jaisalmer in May). Five to seven nights minimum. Air pollution caveat: Delhi's air quality crashes from late October through January, with PM2.5 routinely above 200 µg/m³ on bad days (WHO guideline: 15). Asthmatics should pack masks and consider basing in Jaipur instead.

Kerala (Kochi, Alleppey backwaters, Munnar, Varkala). The lush tropical south. Best October through March, with December–February as peak. Houseboat stays on the backwaters are 1–2 nights; Munnar's tea plantations 2–3 nights. Monsoon (June–August) is a different proposition, dramatic, green, and the traditional season for authentic Ayurveda treatments. Many Ayurveda resorts run their best programs June–August. Just don't expect beach time.

Goa. Beach Goa is binary. Open November through February, peak crowds late December to early January. March–April still warm but humidity climbing. May through September: shut down, beach shacks dismantle, water sports close, many guesthouses padlock.

The Himalayas (Ladakh, Himachal, Manali/Dharamsala/Spiti, Sikkim, Darjeeling). The flip calendar. Ladakh is best late May through September (overland routes open; Leh airport runs year-round but the city wakes up only in late May). Himachal is best March–June and September–November. Sikkim and Darjeeling: March–May for rhododendrons, October–November for the clearest Kanchenjunga views. Avoid Himachal and Uttarakhand in monsoon (July–August), landslides on the highways are routine.

The South interior (Hampi, Mysore, Hyderabad, Madurai, Tamil Nadu temples) and the Northeast (Assam, Meghalaya, Nagaland). Both best November–February for the south, October–April for the Northeast.

Suggested 2-week sketches. Nov–Feb (most travelers): Delhi 2 → Agra 1 → Jaipur 3 → Udaipur 2 → flight to Kochi → Alleppey 2 → Varkala 3 → Kochi 1. Jun–Aug: Delhi 1 → Leh and Ladakh 9 → Srinagar 3 → Delhi 1. Oct shoulder: Delhi → Varanasi → Khajuraho → Agra → Jaipur, before Diwali if possible.

Holi, Festival of Colors (March 3, 2026; Holika Dahan March 2). Spring festival celebrating Krishna and the triumph of good over evil. Iconic places: Mathura and Vrindavan (Krishna's mythological birthplace, most religiously intense, week-long temple celebrations); Pushkar has become the international-traveler Holi capital, big organized parties at hotels and on the ghats; Jaipur does an elephant-festival-adjacent celebration; Udaipur's royal Holi at the City Palace is the upscale option. Trade-offs: hotels run 2–3x normal rates and book out 3–4 months ahead. Wear clothes you'll throw away, oil skin and hair before going out, dry-bag your phone. Some street colors are toxic, buy organic gulal in advance.

Diwali, Festival of Lights (November 6–11, 2026; main night Nov 8). Five-day Hindu festival of lights, gifts, sweets, and family, comparable to Christmas in scale. Travel impact: the biggest domestic travel surge of the year. Flights to/from Mumbai, Delhi, Kolkata, Bangalore, Chennai run 2–3x normal, trains sell out a month ahead. Cultural payoff: every city is lit with oil lamps; Varanasi's Dev Deepawali (full moon two weeks after Diwali, November 25 in 2026) lights a million lamps on the ghats. Air quality crashes, fireworks plus Punjab stubble burning push Delhi PM2.5 to 400+ the day after. Book international and domestic flights 3 months ahead.

Pushkar Camel Fair (November 1–9, 2026; Kartik Purnima Nov 5). Annual livestock fair in the small Rajasthan pilgrimage town that turns into a 200,000-person spectacle of camels, horses, folk performances, and Hindu pilgrims bathing in Pushkar Lake on Kartik Purnima. Photographically iconic. Hotels in Pushkar and Ajmer book 6+ months ahead at 3–5x normal rates; many travelers stay in Ajmer (15 min away) or in tented camps set up for the fair.

Other festivals worth knowing. Durga Puja (Kolkata, October 15–22, 2026), Bengal's biggest festival, the city becomes one giant outdoor art installation. Onam (Kerala, August 26–September 5, 2026), Kerala's harvest festival, snake-boat races, flower carpets. Kumbh Mela rotates between four cities; Maha Kumbh in Prayagraj 2025 drew an estimated 600 million pilgrims; the next major Kumbh is Nashik 2027. Republic Day Parade (January 26, Delhi), military parade on Rajpath, hotels packed. Hornbill Festival (Nagaland, December 1–10), showcase of Naga tribal culture for travelers willing to navigate inner-line permits.

If you can route a trip around one festival, make it Holi (March), Diwali if you don't mind premium prices and pollution, or Pushkar for the photographic spectacle.

Visa. Most Western passports apply for the Indian e-Visa at indianvisaonline.gov.in (the only official portal, third-party scam sites charge triple). 2026 fees: 30-day double-entry tourist e-visa $25, 1-year multi-entry $40, 5-year multi-entry $80, plus 3% bank fee. Apply 4–30 days before travel; processing 24–72 hours. The e-Visa allows entry through 28 designated airports and 5 seaports including Delhi, Mumbai, Kolkata, Chennai, Bangalore, Kochi, and Goa, but for land borders (e.g., from Nepal) you need the regular paper visa.

Trains. Book through IRCTC (the official portal) or 12Go Asia / Cleartrip (English UI, foreign cards). Class hierarchy from cheapest: Sleeper ($5–15) → 3AC ($25–40) → 2AC (~$40–60) → 1AC ($60–100). 3AC is the sweet spot, air-conditioned, curtains, charging points, decent sleep. Tatkal (last-minute) bookings open 24 hours before departure.

Domestic flights. Essential for big distances. IndiGo (dominant low-cost), Air India, Vistara, Akasa run dense networks at $30–100 one-way. Book 3–4 weeks ahead; Diwali and Christmas–New Year need 2–3 months.

Daily costs in 2026. Backpacker (hostels, street food, sleeper trains): $25–40/day. Mid-range (3-star hotels, AC trains, occasional flight): $60–120/day. Comfort (4–5-star, restaurants, private drivers): $200–400/day. Two adults, 2 weeks, mid-range, Delhi–Agra–Jaipur–Udaipur–Kochi loop: $1,800–3,400 on the ground, plus international flights ($900–1,800 per person).

Food safety, the "Delhi belly" question. Bottled or filtered water only (tap is unsafe). Skip ice in non-tourist places. Avoid raw vegetables and unpeeled fruit unless you washed them yourself. Eat at busy places with high turnover, locals at a thali shop is a signal of safety. Vegetarian shifts the odds, most of India's safest food is vegetarian. Pack ORS sachets and ask your travel doctor about an antibiotic prescription (azithromycin is standard).

Health. CDC-recommended vaccines: routine boosters, Hepatitis A and Typhoid (essential), Hep B, and for longer rural stays Japanese encephalitis and rabies. Malaria is patchy, most tourist routes are low risk. Dengue is widespread in monsoon, DEET or picaridin, long sleeves at dusk. Air pollution in Delhi from late October through January is genuinely dangerous; pack N95 masks.

Scams. Classic Delhi tricks: "Your hotel is closed/burned down" (driver pushes a partner hotel, call your booking to confirm); fake travel agents in Connaught Place and Paharganj; gem and carpet shop commission runs; fake monk donations; taxi meter manipulation. Use Ola, Uber, or InDrive in cities; confirm tuk-tuk fares in advance. Theft is real on overnight trains, chain your bag to the seat post.

Etiquette. Right hand only for eating, giving, receiving (left is considered unclean). Shoes off in temples, mosques, gurudwaras, most homes. Cover head and shoulders in religious sites. No leather in some Hindu temples. Dress modestly, covered shoulders and knees, especially outside Goa. Public displays of affection are frowned on. Tipping: 10% at restaurants, ₹50–100 for hotel staff, ₹50–100 per day for drivers.

Money. Indian Rupee (INR), non-convertible internationally; exchange before leaving the country. ATMs everywhere; foreign-card fee around $4–6 per withdrawal. Cards work at hotels and mid-up restaurants; cash essential rurally and for street food, tuk-tuks, small shops. UPI dominates for locals but is hard for foreigners without an Indian bank account. English is widely spoken in tourism, business, and cities.

Solo female travelers. Most solo women report the established tourist circuit (Kerala, Rajasthan, Goa, Himachal, Sikkim, Ladakh) as fine to excellent. Friction concentrates in Delhi (especially after dark), Varanasi (intensity not danger), and small-town North India, staring is constant; harassment occasionally crosses into uncomfortable. Mitigations: arrive in daylight, Uber/Ola not flagged taxis, dress conservatively in non-tourist areas, single rooms not dorms in lower-budget northern hotels, women-only train compartments when available, trust your gut and walk away early.
