International arrivals ordinarily use Bandaranaike International Airport (CMB) near Colombo, then continue by road or the southbound coast railway. Sri Lanka Railways lists Weligama and Mirissa as named stops, but service times, disruptions and reservations must be checked using the official timetable. Buses and pre-arranged car/van transfers are possible road alternatives; do not assume a direct airport train. Mirissa harbor is for booked local whale-observation boats, not an established passenger ferry. No reliable inter-destination sea transfer or dive liveaboard gateway was documented for this bounded visitor cluster.

Main international arrival gateway near Colombo/Katunayake. Continue by pre-arranged ground transport or connect to Sri Lanka Railways Coast Line; neither is a same-airport direct sea transfer.

Use short road transfers, tuk-tuks and operator pickups between accommodation and activity meeting points. Mirissa Collective advertises paid tuk-tuk pickup for some experiences, with the exact fare calculated by distance and a different arrangement for whale harbor departures. Ask the specific dive shop which beach/harbor it leaves from. Trains serve both named towns but are not substitutes for a pre-dawn whale-boat transfer. No exact trip durations or fares were assumed.

As of the 25 May 2026 official rule, all foreign nationals require a pre-arrival Electronic Travel Authorization (ETA), even nationalities currently eligible for a free 30-day tourist ETA. The official ETA portal lists 40 eligible passports, including the United States, United Kingdom, Spain and many others; this is not a universal free visa. Follow the current nationality-specific fee and application rules rather than an old travel blog. Immigration entry guidance calls for a passport valid at least 6 months from arrival, a return/onward ticket and adequate funds. Extension procedures and eligibility must be checked with Immigration before travel.

Both confirmed scuba operators advertise equipment packages: Mirissa Collective lists regulator, BCD, wetsuit, mask, fins and tank; Weligama Bay Diving Centre states its fun dives include equipment and a local guide. Confirm sizes, weights, tank fill, dive-computer availability, emergency oxygen, specialty or camera gear, charges and any medical paperwork. Bring qualification documents and personal mask if fit matters. For snorkel, verify guide, life jacket and tide on the actual date. No reliable enriched-gas or technical fill supply was verified.

The Central Bank confirms LKR as domestic legal tender. Local activity operators can publish LKR prices or other currency quotes; ask which currency will actually be charged. Carry enough small local notes for informal transport and daily expenses, and use electronic payments only where offered.

Plan cash withdrawals in serviced town or transport hubs such as Weligama and Mirissa, but no specific ATM address, uptime, withdrawal limit or fee was independently verified. Keep a backup payment method and arrange cash before early boat departures.

Type G is Sri Lanka's official socket standard under the public utility regulator, though legacy D and M socket formats may remain in older properties during the transition. Bring a quality Type G adapter and check your chargers accept 230V/50Hz; an adapter alone does not convert voltage. See country electrical reference.

Communications

SLT-Mobitel and Dialog advertise tourist prepaid SIM/eSIM products, including airport pickup or activation with a passport. Check current data allowance, eSIM device compatibility and signal at the actual lodging. Share a working phone number with the activity operator, and download maps before boat or lagoon outings; offshore mobile reception is not a rescue plan.

Language

Sinhala and Tamil are Sri Lanka's official languages. English is commonly used by tourism-facing dive and activity operators; the PADI listings reviewed advertised English among their operating languages. Confirm the language of the safety briefing and medical questionnaire rather than assuming it.

Insurance

Purchase a policy that explicitly covers scuba to your certified depth, DCI/recompression, emergency evacuation, boat outings and any contemplated surf/freedive activity. Confirm policy exclusions for introductory scuba, rented equipment and weather cancellations. SLTDA expects operator insurance but that does not replace personal coverage. FCDO health guidance warns private medical care and medical evacuation can be expensive.

Packing list

Bring a passport/ETA record, sun clothing, washable quick-dry layers, personal mask if preferred, reef-aware sunscreen, water bottle, suitable footwear for wet rock, small dry bag, seasickness precautions when appropriate and a Type G adapter. Divers should bring certification and medical history; surf students a rash guard, and kayakers any water-safe prescription eyewear. Do not pack wildlife-baiting food or assume unfamiliar equipment sizes will be in stock.
