When you think of hiking in Iceland, you likely imagine epic volcanic landscapes, sweeping mossy valleys, and glacial rivers cutting through vast black deserts. What’s often overlooked, however, is one of the most delightful parts of the experience: Icelandic trail snacks.

Locals don’t just hike with granola bars and protein shakes — their packs are filled with traditional Icelandic treats that fuel the body and warm the soul. If you're planning a trek across Iceland’s Highlands or a scenic walk through Lónsöræfi, here are the authentic Icelandic snacks you’ll want to try, inspired by the tastes and habits of real Icelanders.

‍

1. Harðfiskur (Dried Fish) with Butter

Harðfiskur is the ultimate Icelandic hiking staple. It's essentially wind-dried fish, often cod, haddock, or wolffish, dried outdoors until it's chewy and full of umami flavor. Icelanders traditionally eat it with a generous dollop of butter, either spread over the fish or eaten separately as a fat boost.

Why it works: Harðfiskur is protein-packed, light to carry, and keeps well for days, making it ideal for long treks through remote regions. Don’t let the smell put you off — it’s a crunchy, satisfying snack once you get used to it.

2. Flatkaka with Hangikjöt (Smoked Lamb Flatbread)

Flatkaka is a traditional Icelandic rye flatbread, thin and soft, with a slightly smoky flavor from the traditional baking method on hot stones or iron plates. It’s often paired with hangikjöt, Iceland’s beloved smoked lamb.

This combo makes for a hearty and flavorful sandwich, often pre-packed for hikes. The strong smoky meat and earthy rye bread are surprisingly satisfying after hours of climbing steep trails.

3. Nói Síríus Chocolate

No Icelandic adventure is complete without a few bars of Nói Síríus chocolate tucked into your pack. The favorite among locals? Salted caramel. Rich milk chocolate infused with buttery caramel and a touch of sea salt is the perfect balance of sweet and savory.

Why locals love it: It’s more than just a sugar rush. Chocolate gives a psychological boost on the trail, especially during long and challenging hikes like Faxasund or Krakatindur.

4. Þristur (Lakkrís + Chocolate Candy)

Þristur is a wildly popular Icelandic candy made of soft liquorice (lakkrís) coated in chocolate. It’s chewy, sweet, and salty—combining two of Iceland’s favorite snack flavors. It’s especially good on windy summits where a little sugar kick helps beat the chill.

You’ll love this if: You enjoy bold Nordic flavors and want to try something distinctly Icelandic.

5. Rúgbrauð (Geothermal Baked Rye Bread)

Often dubbed “lava bread,” rúgbrauð is dense, dark rye bread traditionally baked by burying it near a hot spring for up to 24 hours. Slightly sweet and incredibly filling, slices of rúgbrauð are perfect with butter, smoked fish, or cheese.

Travel tip: Some areas like Laugarvatn even sell it fresh-baked near geothermal sites. Great to pack for day hikes.

6. BONUS! Icelandic Waffles with Rhubarb Jam & Whipped Cream

While not something you'll pack in your daypack, waffles are a hiker’s reward in many huts and mountain cafés along the trail. Icelandic waffles are thin, heart-shaped, and always served warm with rhubarb jam and whipped cream.

They’re a cultural staple, often homemade, and taste like pure comfort after a day in the elements.

Pro Tips for Packing Snacks Like an Icelander:

• Keep it light but dense: Icelandic snacks are designed to be calorie-rich and weather-resistant.
• Prepare before you go: You won’t find many shops or cafes once you enter the Highlands, so stock up in larger towns.
• Respect the local customs: Eating dried fish with butter might look strange, but it’s deeply traditional.
• Bring extras: Icelandic hospitality often includes sharing. Be ready to offer a piece of chocolate or a waffle to a fellow hiker!

Final Thoughts

Hiking in Iceland isn’t just about the epic terrain — it’s also about experiencing the culture, even in the form of snacks. By eating like an Icelander, you're embracing centuries of survival knowledge wrapped in a surprisingly delicious package. Whether you’re crossing Blautulón lake, traversing Hungurfit’s rugged beauty, or just relaxing near Jökuldalsvegur, make sure your backpack is filled not just with gear, but with a bit of Icelandic tradition.

Happy hiking, and happy snacking!
