Day Trek to Hengill and the Hot Spring – challenging

Exploring Iceland’s wild landscapes often means balancing breathtaking scenery with physical challenge, and this guided day trek to Hengill Mountain hits that sweet spot. While it’s a demanding 9-hour adventure, it offers a chance to witness some of the most dramatic volcanic terrain Iceland has to offer, topped off with a relaxing soak in a natural hot spring. This experience isn’t your typical walk in the park — it’s a full-on, hands-on exploration designed for those who want more than a sightseeing bus tour.

What I particularly like about this trek is how it combines stunning panoramic views with practical outdoor skills like orienteering, all led by a knowledgeable International Mountain Leader. The second thing? The opportunity to take a dip in Iceland’s geothermal waters, surrounded by rugged scenery. That said, you’ll want to come prepared for a challenge, because the route covers 17 km with an elevation gain of over 1,000 meters. If you’re not used to physically demanding hikes or don’t have solid hiking footwear, this might be a bit intense. Still, for those ready to push their limits, it’s a rewarding experience.

One potential consideration is the weather, which can change quickly in Iceland. The tour recommends bringing rain gear, extra layers, and even gloves — no matter how sunny it starts out. Rising to almost 3,400 feet, the summit views are stunning but expect to encounter wind or cooler temperatures at higher altitudes. Also, keep in mind that the tour isn’t suitable for children under 16 or those with mobility issues, so it’s best for active, prepared travelers.

Exploring Hengill: The Route and What to Expect

This trek starts roughly 50 minutes from Reykjavik’s city center, at a convenient parking lot near a power plant, where your guide will be waiting. The journey kicks off around 10 a.m., giving you plenty of daylight to explore and enjoy the day. The 17 km route oscillates between rough volcanic terrain, lush valleys, and rocky cliffs. As I’ve read in reviews, the landscape is constantly shifting, creating a visual feast for your eyes — from steaming geothermal fields to moss-covered lava flows.

Your guide, a seasoned International Mountain Leader, will point out geological features and teach orienteering skills along the way. This isn’t just about reaching the summit; it’s about learning to navigate wild terrain confidently. One reviewer appreciated how her guide “taught the art of orienteering, giving her the skills to navigate confidently using a compass and altimeter,” which adds lasting value to the experience.

The ascent leads to a summit at 1010 meters (about 3,314 feet), offering panoramic views that tend to stay with you long after the day is over. The vistas stretch over volcanic ridges, valleys, and possibly even the distant ocean on a clear day. The sense of achievement at the top, after a challenging climb, is palpable — especially when you realize you’ve also learned something practical along the way.

A highlight for many is the chance to relax in one of Iceland’s natural hot springs. You’ll want to pack your swimsuit and towel for this part, which is included in the tour. Surrounded by striking scenery, soaking in geothermal waters is a soothing reward after hours of exertion. Several reviews mention how rejuvenating it was to wind down with a swim in the mineral-rich waters, while taking in the landscape.

The Art of Orienteering and Hidden Gems

One of the unique features of this tour is the orienteering lesson. Your guide, an expert, will teach you how to read a compass and use an altimeter — skills that turn a hike into an empowering outdoor skill-building session. This may seem like a minor detail, but it’s a rare opportunity to learn navigation in a real-world setting. For anyone interested in outdoor adventures, that’s a big plus.

Along the way, you’ll explore “hidden gems” that are off the typical tourist trail. Your guide will point out geothermal vents and volcanic formations that most visitors never see, adding a layer of discovery to your journey. Several reviews note that the guide’s knowledge and storytelling make the trek not just physically rewarding, but intellectually engaging as well.

Practicalities, Pricing, and Who Should Consider This Tour

This is a full-day experience that lasts roughly nine hours, with a start around 10 a.m. and a return by 7 p.m. The price includes the guide, safety equipment, and the hot spring swim. However, you must arrange your own transportation to the meeting point — a parking lot near a power station — which is about a 50-minute drive from Reykjavik. That’s worth considering if you don’t have a rental car.

The tour is aimed at active travelers aged 16 and above, who are comfortable with strenuous activities. The small group size (up to 12 participants) ensures personalized attention, but it also means that the group will need to be fairly balanced in terms of fitness level. The inclusion of safety gear and an experienced guide makes it suitable for those who are prepared for a challenging hike.

Value-wise, this tour is a great deal for adventure seekers looking for more than just sightseeing. You get a full day of exploring Iceland’s volcanic heart, learning practical outdoor skills, and relaxing in geothermal waters. The price reflects the guide’s expertise and the inclusion of unique experiences like the hot spring swim.

Who Will Love This Experience?

If you enjoy physical challenges, love discovering hidden corners of Iceland, and want to combine outdoor skills with breathtaking scenery, this tour is a strong contender. It’s an excellent choice for those who are comfortable with a demanding hike and want to go beyond the typical Golden Circle.

Travelers seeking a personalized, small-group experience will appreciate the intimate setting and expert guidance. It’s especially suited for active individuals aged 16 and up who are ready to push themselves physically and mentally.

However, if you prefer leisurely sightseeing, or have mobility issues, this might not be the best fit. The focus on a challenging ascent and rugged terrain means it’s best for confident hikers who like a good workout.

Final Thoughts

You’ll come away with new skills, unforgettable vistas, and perhaps a new appreciation for Iceland’s geological forces.

This tour is best suited for adventurous souls keen on exploring beyond the usual, eager to learn, and prepared for a full day of outdoor activity. If that sounds like your kind of trip, it’s well worth the effort and expense.
