Fly into Bandaranaike International Airport (CMB) for the Negombo and Marawila coast. The airport operator confirms supervised airport taxi counters, Uber, PickMe, private taxis and public transport. Negombo is the documented airport-area dive base; Marawila is a separate coastal road transfer and should not be treated as the same pickup point. Book hotel and dive-operator ground transfers directly and compare pickup details, luggage capacity, route, nighttime arrival support and payment terms. No sea transfer or dive liveaboard is needed to reach this land-based destination.

The primary air gateway for a Negombo or Marawila coastal stay. It is not a separate dive-boat port. Verify flight operations and onward ground connections with the airline and airport.

Use a negotiated or metered taxi, app-based ride or prearranged driver for hotel-to-dive-center transfers, especially with cylinders or bulky luggage. Negombo is the primary operating and inquiry base, while Marawila excursions can require a longer ground pickup; do not imply a fixed journey time or launch location without a live operator confirmation. Rail and bus options may be useful for non-diving travel along the west-coast corridor, but stations, schedules, bag limitations and last-mile transport must be verified. Sri Lanka Railways provides the official rail-information starting point. Do not board a working fishing boat as an informal dive transfer.

Check Sri Lanka immigration and the official electronic travel authorization (ETA) portal before travel; immigration rules depend on nationality and travel document. The official ETA fee table, effective May 25, 2026, lists 40 nationalities eligible for a free 30-day tourist ETA, including the United States, United Kingdom, most listed Western European countries and several Asian/Middle Eastern countries. It also lists visa-fee exemptions for Singapore and Seychelles (30 days) and the Maldives (90 days). For other nationalities it lists a 30-day tourist ETA fee of USD $20 for SAARC countries or USD $50 for other countries when applied for by the traveler; arrival processing may cost more and is not a guaranteed entry route. Apply or verify status through the official ETA portal, not a third-party reseller. Passport validity, onward/return ticket, funds, entry permissions and permitted length of stay should be reconfirmed for the specific passport. Dive certifications do not replace immigration documentation.

Local centers advertise packages with rental equipment, but travelers should confirm the actual sizes, recent service, cylinder fills, weights, BCD, mask, regulator, fins, exposure protection and computer before arrival. Confirm whether nitrox is offered, the required certification and gas analysis procedure, and whether a qualified instructor supervises beginner dives. Bring proof of certification and any required medical clearance, fit and check equipment yourself, and keep travel insurance documentation accessible. For boats ask about drinking water, shade, seasickness precautions, dive flags, communications, emergency oxygen, a rescue plan and a dry place for valuables. Packing a surface marker buoy and audible signaling device is prudent where appropriate and permitted. There is no demonstrated fixed rental or filling facility specifically based in Marawila.

Pay ordinary local expenses in Sri Lankan rupees. Some dive operators advertise USD prices, but clarify the accepted payment currency, local exchange calculation, bank surcharge, inclusions and taxes before purchase. Cards may work in larger lodging venues while markets, small vehicles and vendors may require cash.

Cash machines and bank services are available in larger towns such as Negombo, but machine operation, foreign-card acceptance, withdrawal limits and cash availability vary. Carry a backup payment method and small local notes; do not assume an ATM will be available at a particular Marawila hotel.

Type G is the national standard per the electricity regulator; older Type D installations may remain. Check the actual property outlets and use a compliant adapter with dual-voltage electronics. A plug adapter alone does not convert voltage.

Communications

Airport mobile-service counters can provide local SIM options, and hotels commonly advertise connectivity, but signal quality at offshore sites and Marawila properties must be checked. The airport lists mobile communication services. Arrange an operator telephone or WhatsApp contact in advance and download essential addresses and permits offline. Mobile data is not a substitute for marine emergency communications.

Language

Sinhala and Tamil are official languages of Sri Lanka; English is widely used for many visitor transactions and may be available at dive centers, but do not assume every boat crew member or driver speaks it fluently. Confirm that a dive briefing and emergency instructions can be understood by each participant.

Insurance

Choose travel insurance explicitly covering recreational scuba to the intended certified depth, emergency oxygen and medical care, search and rescue where applicable, decompression illness treatment, recompression-chamber care and medical evacuation. Standard travel policies may exclude diving, freediving, higher-risk wreck work or boat operations. Ask the operator what liability/participant insurance it carries, then verify your own coverage and emergency contact procedure. No local chamber or insurer payment acceptance is guaranteed.

Packing list

Pack light quick-drying clothes, swimwear, sun protection, rain shell for transition months, repellent, reusable water bottle, reef-safe skincare, sandals and footwear with grip for wet areas. Divers should bring proof of certification, dive computer if available, appropriately fitting personal mask and insurance information. For coastal boats, use a dry bag, a secure phone pouch, a sun hat that will not blow away and a seasickness strategy approved by your clinician if needed. Bring a Type G plug adapter and check whether Type D is in use at older properties.
