From SEA airport to Reykjavik

Reaching Seattle-Tacoma International

Light Rail (best option): Sound Transit's Link Light Rail runs from downtown Seattle's Westlake Station to SEA in 41 minutes for $3.50 one-way (off-peak) or $5.00 (peak, weekdays 6-9am, 4-6pm). Trains run every 10-15 minutes 5am-midnight, every 20 minutes after. Much cheaper than a rideshare and no traffic stress. Rideshare (Uber/Lyft): $28-$42 from downtown Seattle (20-30 min depending on traffic), $18-$28 from Tacoma. Rental car with parking: Pick up from Enterprise/Hertz downtown, then park at SEA. Parking runs $16/day economy (further out) to $32/day valet. If you're renting a car anyway, this beats light rail plus a car rental at your destination.

Getting from KEF into Reykjavik

Flybus (operated by Strætó) is the standard airport transfer — runs every 30-45 minutes, costs ~3,500 ISK ($25) one-way to the BSÍ bus terminal in central Reykjavik, or ~4,500 ISK ($33) with a hotel drop-off add-on. Journey is 45-60 minutes. Taxis from KEF to the city center cost 15,000-18,000 ISK ($110-130) and take the same time — almost never worth it unless you're splitting four ways with heavy luggage. Rental cars are the third option and make sense if you're picking one up anyway, since KEF has all major rental desks on-site; driving to Reykjavik city center is straightforward on Route 41, about 50 minutes.

Planning Seattle to Reykjavik

Reykjavik is the world's northernmost capital and one of the most geologically alive places on Earth — geysers, waterfalls, lava fields, and the Northern Lights are all within a two-hour drive. For Americans, it's an easy first international trip: English is universally spoken, crime is basically nonexistent, and the food has leveled up dramatically from its fermented shark reputation. The city itself sits on a peninsula jutting into the North Atlantic, and on a clear day you can see the Snæfellsjökull glacier from the waterfront promenade.

Best-month weather in Reykjavik

June

46–56°F · 10 rain days

Midnight sun peaks around June 21st with nearly 24 hours of daylight — the sun barely dips below the horizon. Warm by Icelandic standards, popular festivals, but this marks the start of peak tourist season with prices spiking.

July

49–59°F · 11 rain days

Peak summer — warmest month of the year with long bright evenings and all outdoor attractions fully operational. Crowds are at maximum, rental cars sell out weeks in advance, and popular spots like Fjaðrárgljúfur canyon get genuinely jammed.

The destination guide flags November and December and January as the least favorable months.

Two areas to consider

101 Reykjavik (City Center)

mid-range

The heart of the city centered on Laugavegur shopping street, Hallgrímskirkja church, and the waterfront Harpa concert hall. Everything walkable, best bar and restaurant density, but also highest accommodation prices and tourist-to-local ratio. Stay here your first time.

Þórshöfn / Hlemmur Area

mid-range

Just east of dead center around Hlemmur food hall and bus terminal, this area has become genuinely cool — Messinn for fish, Kex Hostel for affordable beds, and slightly lower prices than the immediate Laugavegur strip. Five-minute walk from everything that matters.

Local planning tip

Skip the Blue Lagoon for your first soak and instead go to the Reykjadalur hot river hike — it's a 3km trail south of Reykjavik near Hveragerði that ends at a naturally heated river where you can soak for free. The Blue Lagoon runs $80-120 per person and feels like a water park; the Reykjadalur river is actual geothermal Iceland with steam rising off the water and nobody handing you a silica mud mask. If you insist on the Blue Lagoon, book the first time slot of the day (7am) to beat the bus tours, or the last slot at 9pm for sunset lighting — never go midday.

Visa and entry notes for US travelers

US passport holders enter Iceland visa-free for up to 90 days within any 180-day period under the Schengen Agreement. Iceland is part of Schengen but not the EU. No advance visa application needed — just show up with a valid US passport, proof of onward travel, and sufficient funds. ETIAS (the European Travel Information and Authorization System) launches for US citizens in 2025; it costs €7, takes 10 minutes to apply online, and is valid 3 years. You'll need ETIAS before your flight. US citizens don't pay departure taxes separately — it's included in your airfare.
