Kerlingarfjöll

One of Iceland’s most surreal and spectacular mountain ranges, nestled deep in the central Highlands. Known for its vibrant orange rhyolite hills, steaming geothermal valleys, and snow-capped peaks, it looks like a living painting — a place where fire and ice meet in full force. The moment you arrive, you’re met with the sight of colorful mountains shrouded in mist, dotted with fumaroles and hot springs releasing plumes of steam into the cool air. The area is a paradise for hikers, with well-marked trails ranging from short scenic walks to challenging multi-hour treks through geothermal zones like Hveradalir, where boiling mud pots and sulfur vents hiss beside snow patches. The contrast of colors — deep reds, golden yellows, milky blues, and stark white — creates one of the most dramatic landscapes in Iceland. Every corner feels alive, with the earth literally steaming beneath your feet. Access requires a 4x4 vehicle, as the highland F-roads can be rough and occasionally include river crossings. The best time to visit is during the short summer season, from late June to early September, when the area is snow-free and trails are open. Weather can shift quickly, so layers, waterproof gear, and sturdy hiking shoes are essential. There’s also a mountain resort nearby, offering cozy accommodations, warm meals, and even natural hot spring baths — perfect after a long day of exploring. More than just a hiking destination; it’s a sensory experience that feels almost unearthly. The colors, the heat, the silence, and the vastness combine to make it one of Iceland’s true hidden treasures. Few places capture the essence of Iceland’s volcanic heart as powerfully as these fiery mountains.

Simply breathtaking and unique views to enjoy here. You can drive up for easier access, but we chose to hike up from the nearby base camp. In all it was roughly an 8.5 mile loop, but was very tiring due to the elevation climb. We were absolutely beat after the full loop, but would definitely do it again due to the incredible views. Hiking up, we got to look over the valley and nearby glaciers. Then climbing over a snowcap drops us into this colorful valley that felt a bit like an oasis. The colors were stunning and almost unnatural from staining due to sulfur and minerals. Add in the natural hot vents and constant steam for a truly ethereal experience. Lots of different paths to explore and enjoy, but be prepared for a lot of different stairs to climb and descend. Recommend spending a bit of time here to walk around and enjoy all that the area has to offer.

Absolutely stunning place! I can safely say it’s an adventure for thrill-seekers. Here’s what I recommend before you go: •Rent a 4x4 vehicle, get premium insurance, and fill up the tank. The off-road part of the journey took 2 hours one way. •Dress warmly in waterproof and windproof clothing: thermal layers, a hat, a neck gaiter, and gloves — you’ll need everything. Waterproof boots are a must. •Bring ready-to-eat food; there’s no opportunity to cook along the way. •Don’t drink too much water and make sure to use the restroom at Gullfoss waterfall before setting off. •Hiking can be quite dangerous: wind gusts up to 20 m/s, occasional rain and snow, temperature around +3°C, slippery clay stairs, and no railings. •Bring an adventurous spirit and plenty of patience — the route is long and exhausting, but absolutely worth it. Good luck!

This was one of our favorite hikes. It’s a long way up to get there by 4x4 with rough road conditions but worth it for outer worldly landscapes. Our Dascia Duster made it to the top parking lot past the resort. Very steep near the end getting to the lot.

Incredible hike. Challanging but fun and definately worth it. There’s a parking spot also so you can drive up to it if you’re not feeling like hiking much.

The must stunning place in Iceland! Worth going there from Reykjavik! You have plenty of hiking trails with a different level of difficulty, parking is small but sufficient! It’s worth going there regardless the weather and season!

The most beautiful place in Iceland, only 4x4 it’s allowed

One of the most incredible places in Iceland. Beautiful hikes.
