Can’t decide whether you should visit Iceland in summer or winter? September in Iceland offers the best of both worlds. As tourist season winds down, you can still do summer activities like hiking, kayaking, and boat tours. At the same time, Iceland gears up for winter adventures like ice caving and snowmobiling.
September is a great month to visit Iceland if you want to avoid crowds and sample a bit of everything. Best of all, the Northern Lights make their seasonal debut!
Here are our favorite things to do and see in Iceland in September.
What to Do in Iceland in September
Snowmobile Across the Glaciers
Revving up to go on a glacier
With winter in sight, but clear skies ahead, there’s no better time to explore Iceland’s winter sports. Feel the true size of Iceland’s glaciers as you dash across them in a snowmobile. No prior experience is needed for our snowmobiling tours, making for a great family adventure.
Snowmobile lovers are especially fond of Langjokull Glacier, the second-largest glacier in Iceland. The ice is thick, the terrain is flat, and the snow is unspoiled — everything you need for a safe and thrilling adventure.
Hike the Glaciers
Glacier hiking - the ultimate bonding experience
If you prefer to explore the ice on your own two feet, glacier hiking is the sport for you. Even beginning hikers can explore the ridges, crevasses, and labyrinths of Iceland’s ice caps.
The largest glacier in Iceland, Vatnajokull, has 30 outlet glaciers that are excellent for hiking. Also on the South Coast, Sólheimajökull Glacier is easy for beginners and has scenic views of Iceland’s most famous volcanoes.
Kayak in Calm Waters
Kayaking in Iceland
September is your last chance to kayak on Iceland’s peaceful lagoons and shorelines.
Jokulsarlon Glacier Lagoon is the deepest lake in Iceland and a popular kayaking spot. The lagoon glitters with blue icebergs from the surrounding glaciers. Even beginner kayakers can paddle their way around the calm, crystal-clear waters. From Jokulsarlon, you can visit nearby Diamond Beach, one of Iceland’s most famous destinations.
If you’re staying closer to Reykjavik, the capital city area also offers easy sea kayaking. The calm sea around Geldinganes Peninsula is a major draw for tourists — and wildlife. Keep your eyes peeled for seals and seabirds!
Dip Into Geothermal Swimming Pools
Yes that's the Blue Lagoon
As temperatures grow colder in September, you can find relaxation in Iceland’s hot pools. The famous Blue Lagoon is open year-round and stays at a steady temperature of 100°F (38°C).
For geothermal pools that are more off-the-beaten-path, visit the Myvatn Nature Baths in the North and the Secret Lagoon in the Southwest.
Drive the Ring Road
Iceland behind the wheel
In September, the weather is fine and the roads are mostly clear. Sounds like the perfect time to set out on the world’s best road trip! Iceland’s Ring Road (Route 1) loops around the entire country and makes for a memorable week. Go with a guide to make the most of your trip.
Best Things to See in Iceland in September
Vibrant Fall Colors
Seasons turn rapidly in Iceland. September is considered the only real autumn month before winter sets in. However, Mother Nature more than makes up for the short season with incredible fall colors.
Head to Iceland’s birch forests to discover beautiful shades of red, gold, and green. Hikes through Thingvellir National Park or Heiðmörk Nature Reserve are the ultimate fall fantasy.
Your best bet for catching the lights is one of our Northern Lights tours. Each night, expert aurora guides head out with visitors to hunt down the lights. Anyone can check the weather and aurora forecasts, but it’s our guides who have the inside scoop on the best places to see the Northern Lights!
Whale watching from Dalvik
Iceland’s puffins migrate south in September, but the whales are here to stay. The coastlines are home to humpback whales, minke whales, dolphins, and porpoises. If it’s the right season, you may even catch a glimpse of a blue whale!
Whale watching tours launch from Iceland’s harbors throughout the year. In September, the weather is clear for high visibility while chillier waters tend to attract more whales.
If you’re staying in Reykjavik, you can hop on a whale watching tour from the Old Harbor. For even better chances of making a sighting, head north to Dalvik, the whale watching hub of Iceland.
Events and Festivals in September in Iceland
Réttir Sheep and Horse Roundup
See Iceland at its quirkiest at the annual horse and sheep roundup. Réttir is one of the oldest folk traditions in Iceland. Throughout September, farmers invite locals and tourists to help herd horses and sheep back to the farm after their summer grazing. Days are filled with walking and horse riding and followed by evenings of celebration.
Horse roundups mostly happen in the North, while sheep get rounded up throughout the country.
