By air: Fly to Keflavík International Airport (KEF), 45 minutes from Reykjavík. Direct flights from most European hubs, plus North America.
From Reykjavík: Most dive operators offer pickup from central Reykjavík. Otherwise, rent a car for maximum flexibility (Iceland is best explored independently). Bus routes are limited and not ideal for dive gear.

The vast majority of diving is accessible from Reykjavík or nearby. Stay in central Reykjavík for widest accommodation choice (guesthouses, hotels, hostels, apartments). Book early for summer high season. For north/coastal dives, plan a 1–2 night stay in Akureyri or small-town lodges.

Cold water diving — dry suit required. Conditions are generally calm, but prepare for cold topside winds year-round. Some sites are suited for all certified divers (with dry suit experience), others for advanced/tech divers.
All dives are land-based or short-boat rides. No liveaboards or dive resorts. Day trips only.
Divers must be age 17+ (18+ for National Park dives). Most operators require documented dry suit experience (certification or proof of 10 dry suit dives in the past 2 years).
Silfra: Dive time 30–40 min, max depth 18 m (59 ft). Tours are extremely popular—book ahead.
