Here’s our guide to some of the best hikes in Iceland, plus practical tips to help you plan an unforgettable trip on foot and behind the wheel.

1. Glymur Waterfall – A hidden gem close to Reykjavik

📍 Distance: 6.5 km round trip
📷 Why go: Iceland’s second-highest waterfall, less crowded than more famous sites

Located just an hour from Reykjavik, Glymur is a fantastic introduction to Icelandic hiking. The trail winds through a cave, across a river (with a log crossing in summer), and up to sweeping views of the 198-meter-high waterfall. It’s a moderate hike, great for half-day adventurers and photographers seeking a less-touristed gem.

Pro tip: Wear waterproof boots—the river crossing can be tricky after rain.

2. Reykjadalur Valley – Hike to a hot spring river

📍 Distance: 6 km round trip
📷 Why go: Steam-filled valleys, geothermal pools, and a relaxing dip at the end

Reykjadalur (Steam Valley) is one of the most unique hikes in Iceland. The trail climbs gently through colorful hills before opening to a valley dotted with steaming vents. At the end, you can soak in a warm river—a natural hot spring perfect for resting sore legs.

Pro tip: Pack a swimsuit and towel in your daypack and go early to avoid crowds.

3. Fimmvörðuháls – From waterfalls to volcanic craters

📍 Distance: 25 km one-way
📷 Why go: Crosses between two glaciers, passes recent volcanic eruptions, endless waterfalls

For seasoned hikers, the Fimmvörðuháls trail is an iconic challenge. Stretching between Skógafoss and Þórsmörk, this epic route passes over 20 waterfalls, a lava field from the 2010 eruption, and spectacular glacier views. It’s typically done in one long day or split over two with an overnight hut stay in Þórsmörk.

Pro tip: Arrange transport or car pickup in advance—Zero Car Rental makes it easy to reach both trailheads.

4. Landmannalaugar – Iceland’s hiking crown jewel

📍 Distance: Varies (from 4 km loops to multi-day treks)
📷 Why go: Rainbow-colored rhyolite mountains, lava fields, natural hot springs

The highlands of Landmannalaugar offer some of the most surreal scenery in the country. Choose from shorter loops like Laugahraun or longer trails leading into the Laugavegur trek. The contrast of colorful mountains, black lava, and steam rising from the ground makes for striking photos.

Pro tip: Accessible only in summer with a 4WD vehicle—Zero’s fully insured rentals with roadside assistance have you covered.

5. Laugavegur Trail – The ultimate Iceland trek

📍 Distance: 55 km (Landmannalaugar to Þórsmörk)
📷 Why go: Iceland’s most famous multi-day trail through geothermal valleys, glaciers, and rivers

Named one of the world’s best hikes by National Geographic, the Laugavegur trail is an unforgettable journey. Typically hiked over 3–4 days, it winds through some of Iceland’s most dramatic landscapes. Stay in mountain huts or bring a tent for the full backcountry experience.

Pro tip: Plan transportation carefully—Zero Car Rental gives you the flexibility to explore at your own pace and reach remote trailheads.

6. Hornstrandir Nature Reserve – True wilderness in the Westfjords

📍 Distance: Varies (multi-day treks only)
📷 Why go: Remote cliffs, Arctic fox sightings, untouched landscapes

For experienced hikers seeking solitude, Hornstrandir is as wild as it gets. Accessible only by boat from Ísafjörður in summer, this region has no roads, no facilities, and no cell service—just raw Icelandic wilderness. Multi-day treks here offer cliffside views, sea bird colonies, and the best chance to spot Arctic foxes.

Pro tip: Rent a car with Zero to drive to Ísafjörður before taking the ferry. It’s a long drive, but worth every kilometer.

7. Ásbyrgi Canyon – A peaceful walk in North Iceland

📍 Distance: 4–8 km depending on route
📷 Why go: Horseshoe-shaped canyon, birch forests, quiet and scenic

Part of Vatnajökull National Park, Ásbyrgi is a tranquil oasis with lush vegetation and interesting geology. It’s a great place for a relaxed day hike with incredible views and is often overlooked by international tourists. The serene landscape offers a perfect contrast to Iceland’s more rugged routes.

Pro tip: Combine this with a visit to nearby Dettifoss for a day of varied photo ops.
