मुंबईMumbai.A field guide for everyone landing for Devcon 8, from down the road or across the planet.

The official e-Visa is the usual route for most nationalities. Apply on the government portal ↗ well ahead of travel, and watch for any conference or business visa guidance the Devcon team publishes.

Devcon can issue a letter to support your visa application, but you need a confirmed Devcon 8 ticket first. Request it at least 90 days before the event; requests made under two weeks out are best effort only. Double-check every detail before submitting, since incomplete info causes delays. Questions: visa@devcon.org.

The letter supports your application; it does not guarantee a visa. If it is not accepted, review your eligibility and explore other applicable visa categories on India's official visa portal ↗ for the latest requirements.

The closest polished business hotel to the convention centre. Expect it to be a Devcon hub.

French-flag luxury with strong restaurants and a pool. Popular with conference crowds.

Atop Palladium Mall. Farther out but plugged into shopping and dining if BKC is full.

Sea-facing icon in buzzy Bandra. Best base if you want cafes, bars, and the seafront after sessions.

South Mumbai polish on Marine Drive. Far from BKC, but a destination in itself.

The most famous hotel in India, on the harbour by the Gateway. A splurge and a sight.

Big rooms, a strong food hall, and a quick run to BKC outside peak. Reliable conference base.

Near the airport, handy for short trips and early flights, with a quick hop to BKC off-peak.

Beachfront, with a famous Sunday brunch. Trade venue distance for the seaside.

Across from the terminal. Great for arrival night or an early departure.

Solid four star on the beach with good value rooms and pool. Popular and books out fast.

Reliable mid range value near the airport. Reserve refundable rates early for event week.

Decent business hotel close to the airport and a manageable run to BKC off-peak.

Clean, no-frills, dependable. A safe pick for solo builders watching the budget.

The budget-friendly Bloom chain runs 50+ hotels across India, including several in Mumbai, and this one is the closest to the venue. Compact, well-run rooms and some of the cheapest beds this near BKC. Expect it to book out early.

Tidy boutique by the Gateway. Far from BKC, but unbeatable for sightseeing South Mumbai.

Modern backpacker hostel with dorms and private rooms. Good for meeting other attendees.

India's best known hostel brand. Social, cheap, and used to international travelers.

Pali Hill and Bandra are full of boutique hotels and serviced apartments. Best vibe per rupee.

• Sealed bottled water with an intact seal (Bisleri, Aquafina, Kinley, Himalayan). Hotels usually provide it free.
• Boiled or RO filtered water from your hotel.
• Hot tea and coffee, since boiling makes them safe.
• Sealed cans and bottles, and fresh coconut water from the shell.

• Tap water, including for brushing teeth. Use bottled.
• Ice from unknown sources and street stalls.
• Raw salads and pre-cut fruit washed in tap water at carts.
• Refilled "bottled" water. Always check the seal cracks when you open it.

Bring ORS rehydration salts, an antidiarrhoeal such as loperamide, and ask your doctor about a standby antibiotic for traveller's diarrhoea. Hand sanitiser and your own refillable bottle keep you in the game. Eat hot, freshly cooked food, and pick busy stalls with high turnover over empty ones.

Pharmacies (called chemists) are on every corner; chains like Wellness Forever and Apollo run late. For anything serious near BKC, the big private hospitals are excellent.

• Easiest is an eSIM, but buy and install it before you fly. Travel eSIM stores like Airalo ↗ and Holafly ↗ are not reachable from inside India (app removed, site blocked), so you cannot buy, activate, or top up after landing. An eSIM installed before arrival keeps working, so set it up on home Wi-Fi and buy more data than you think you need.
• Good India eSIM picks: Saily ↗ (best value per GB, runs on Airtel and Jio) and Nomad ↗ (dual Jio + Airtel network). All travel eSIMs skip the local KYC paperwork.
• Best local networks are Jio ↗ and Airtel ↗ for coverage and 4G / 5G. Tourist plans run roughly ₹600 to 1,200 for the trip.
• Physical SIM on arrival: buy at the official Jio or Airtel counter in the airport arrivals hall. Bring your passport, visa, and a passport photo. Activation can take a few hours.
• ID is mandatory (KYC). Use official stores, not street vendors, so it activates reliably.
• Indian residents just need extra data for the conference crowd load.

• UPI is king. Locals pay everything by QR. Visitors can use Google Pay ↗, PhonePe ↗, or Paytm ↗. Foreign visitors can now onboard too, so if you can, set it up before you fly. See UPI for visitors ↗.
• Carry some cash. Autos, small stalls, tips, and temples want rupees. Keep small notes of ₹10, 20, 50, and 100, since change is a perennial problem.
• Cards work at hotels, malls, and nicer restaurants. Tell your bank you are travelling and carry a backup card.
• ATMs are everywhere; use ones attached to banks, withdraw by day, and cover the keypad.
• Currency is the Indian Rupee (INR). Roughly ₹94 to $1 in mid-2026, but it moves, so check the live rate ↗ before you budget.

The 1924 arch on the harbour, Mumbai's defining landmark, with the grand Taj hotel right across.

The Queen's Necklace seafront promenade. Sunset walks, sea breeze, and Chowpatty beach snacks.

UNESCO rock-cut cave temples on an island, about an hour by ferry. Go early to beat heat and crowds.

A UNESCO World Heritage railway station, a Gothic and Indo-Saracenic showpiece, stunning when lit at night.

Street shopping, art galleries, heritage cafes, and the city's creative core. Great for a walk.

Bandstand promenade, Mount Mary, colourful Chapel Road murals, and the best cafe and bar scene near the venue.

A floating mosque and tomb on a causeway into the sea. Go around low tide and dress modestly.

The world's largest open-air laundry, best viewed from the Mahalaxmi station bridge. A photographer's classic.

Sensory overload of spices, produce, and goods. Bargain hard and watch your bag.

• Alibaug ↗: beach town a ferry ride away, good for a relaxed coastal day.
• Lonavala and Khandala ↗: green hill stations about two hours out, lovely post-monsoon.
• Kanheri Caves ↗: ancient Buddhist caves inside a national park, still within the city.

• Colaba Causeway ↗ for clothes, jewellery, and trinkets. Bargain to about half.
• Chor Bazaar ↗ for antiques and curios.
• Spices, tea, textiles, and handicrafts make great gifts. Fixed price stores like FabIndia and Cottons are hassle free.

Crypto is legal to hold and trade, but India taxes gains at a flat 30% with a 1% TDS (tax deducted at source) on transfers above small thresholds, and losses cannot be offset. This mainly matters if you transact on Indian exchanges or as a resident. Read a current summary before doing anything onchain for business here.

India's grassroots scene is huge, with groups like EthMumbai and the Devfolio hackathon ecosystem driving builder energy. Expect side events, hacker houses, and meetups around Devcon week. Watch the official channels and local communities for the schedule.

Between-session deadlines are a solved problem here: the venue's own coworking hall, day-pass desks inside BKC, and Bandra's laptop-friendly cafe scene. The full list lives in the Coworking section.

Treat a conference like any high-target environment. Keep seed phrases and hardware wallets in the hotel safe, do not discuss holdings with strangers, take your badge off in public, and be wary of QR codes and "airdrop" links from people you just met.

Devcon traditionally runs a large coworking hall inside the venue with tables, power, and wifi sized for thousands. Check the official site ↗ and app for quiet zones and call booths before trekking anywhere.

WeWork On-Demand ↗ sells day passes, and its Enam Sambhav building sits inside BKC itself, minutes from the venue. Awfis ↗ has day passes at several Mumbai centres too. Book in the apps; walk-ins during Devcon week are a gamble.

Ministry of New ↗ in Fort is the design-lover's coworking space, and IF.BE ↗, a converted ice factory in Ballard Estate, pairs a cafe with courtyard tables under a banyan tree.

Subko, Mary Lodge ↗ is the nearest of its nine outposts (15 to 25 min from BKC; no BKC branch), with a second Bandra spot inside Art & Charlie ↗. Blue Tokai ↗ and Third Wave ↗ have multiple laptop-tolerant branches.

Cafe Zoe ↗ in Lower Parel is the classic all-day laptop room with proper food. Candies ↗ in Bandra has terraces of seating, and Doolally ↗ tolerates daytime laptops with craft beer on tap. For destination coffee, Araku ↗ in Colaba is a South Mumbai day trip.

• Order something every hour or so; tables are the rent.
• Take calls outside, especially in small rooms.
• Afternoons get packed; mornings are the reliable window.
• Carry a hotspot-ready SIM (see section 06): cafe wifi varies wildly.
• Power sockets are scarce; arrive charged, pack a power bank.

• Default to app cabs (Uber / Ola) for transparent, tracked, shareable rides, especially at night.
• In autos and kaali-peeli taxis, insist on the meter or agree the fare before you start.
• Take the Metro during rush hour; it is the only thing that ignores traffic.
• Download Google Maps offline for Mumbai and install m-Indicator for live trains and buses.
• Carry small cash for autos and stalls, and keep your hotel address saved and on paper.
• Cross roads carefully and follow locals; traffic does not always stop. Use footbridges where they exist.

• Keep valuables zipped and in front in crowds, trains, and markets. Petty pickpocketing is the main risk, not violence.
• Do not flash expensive gear; take your conference badge off in public.
• Politely ignore touts and "free" offers, unsolicited guides, gem deals, or anyone steering you to a specific shop.
• Women travellers: use women-only Metro and train coaches, prefer app cabs at night, and dress as locals do in conservative areas.
• Keep digital and paper copies of your passport, visa, and ticket.
• Buy travel and medical insurance before you fly, and save your embassy's number.

Most foreign nationals need a visa, and Devcon can issue a ticket confirmation letter to support your application. Full details, timelines, and official links are in the Visa and entry section at the top of this guide.

Warm and a little humid, roughly 22 to 33°C (72 to 91°F), and mostly dry. Pack light breathable clothes, sunscreen, and a thin layer for over air-conditioned venues.

UTC plus 5:30, yes the half hour, and no daylight saving. Plan calls home accordingly.

English is widely spoken in business and hospitality. Hindi and Marathi are local. A namaste, a dhanyavaad (thanks), and a smile go far.

Casual is fine for the city and the conference. Cover shoulders and knees at temples and mosques, carry a scarf, and remove shoes at religious sites and many homes.

Not mandatory but welcome: about 5 to 10% at restaurants (check if service charge is already added), round up for cabs, and ₹50 to 100 for hotel help.

Use your right hand for eating and giving. Ask before photographing people. Bargaining is normal in markets, not in fixed-price shops and restaurants.

Use hotels, malls, cafes, and the venue. Carry tissue and hand sanitiser, since many public toilets lack paper.

Air can dip, and it is worse around Diwali fireworks. If you are sensitive, pack a mask or inhaler, and check the live index.

This guide is text and visual only with no audio, so it works without sound, and the toolbar (bottom left) adds larger text, high contrast, reduced motion, and underlined links. For step-free access, captioning, sign language, and quiet rooms at the event, check the official Devcon site ↗. Note that Mumbai streets and older sites can be uneven, so plan accessible transport ahead.

• Namaste (Hindi) / Namaskar (Marathi) for hello.
• Dhanyavaad for thank you (both languages); shukriya in Hindi.
• Kitna? (Hindi) / Kiti? (Marathi) for how much.
• Kam teekha for less spicy, and paani for water.
• Yes / no: haan / nahi (Hindi), ho / nahi (Marathi).
• Marathi: Kasa aahes? (how are you), barr (okay, good).
• Chalega (Hindi) / Chalel (Marathi) means "that works," the most useful word in Mumbai.
