Reykjavik: Lava Cave, Hot Springs, and Waterfalls Tour

The most memorable part of this West Iceland day is Viðgelmir Lava Cave, where a wooden walkway leads into a long, colorful tunnel formed by an ancient eruption. Above ground, the tour brings you to Hraunfossar, a wide series of waterfalls flowing from a lava field, plus steaming Deildartunguhver and the historic site of Reykholt.

I like the mix of nature and history. You get dramatic waterfalls and hot springs, but also Snorralaug, the bathing pool linked to medieval writer Snorri Sturluson. I also like the small group, capped at 19 people, and the chance to ask questions without being lost in a big coach crowd.

The main drawback is the long day. You may spend up to 10 hours on the road, and the cave is not suitable for wheelchair users or people with mobility impairments. Lunch is not included, so bring cash and expect a full sightseeing schedule rather than a relaxed spa day.

Key points to know before booking

• Viðgelmir is the star attraction: The guided cave visit lasts about 1.5 hours and includes admission.
• Hraunfossar is unusually broad: Water streams out through a lava field along roughly 900 meters, creating several viewpoints and photo stops.
• The tour connects Icelandic nature with saga history: Reykholt and Snorralaug add cultural depth to the waterfalls and geothermal stops.
• Small groups make a difference: The maximum group size is 19, with free Wi-Fi on the bus and an English-speaking guide.
• Plan for a long, active day: You will walk at the waterfalls and inside the cave, with wet conditions possible underground.
• Bring your own meal money: Food is not included, and the day includes a lunch stop and an afternoon coffee break.

Why this West Iceland route is worth your day

At $210 per person, this is not a bargain bus ride, but it covers a lot of ground. You are paying for transport from Reykjavík, a full-day route into Borgarfjörður, the Viðgelmir entrance fee, a dedicated cave guide, and a group limited to 19 passengers.

I see the value in the combination. Many day trips give you waterfalls or geothermal sights, then turn around. This one adds a proper lava cave and the Reykholt area, so the day has more variety. You are not simply checking off viewpoints. You see how volcanic activity shaped the region, then connect that geology with medieval Icelandic history.

The route also suits you if your Iceland trip is short. West Iceland can be awkward to cover without a car, especially when you want both Viðgelmir and the waterfalls. A tour removes the need to plan the driving, parking, and timing yourself.

Still, the price does not include lunch. You should also understand that the day is built around several stops, not long periods at one site. If you prefer slow travel, a private rental car may give you more freedom. If you want a well-filled day with a guide and minimal planning, this is a sensible use of time.

From Reykjavík to Glanni Waterfall

Pickup in Reykjavík usually takes place between 8:30 and 9:00 in the morning. Because large buses cannot enter certain central streets, your pickup may be at a nearby designated bus stop rather than directly outside your accommodation. Have your phone ready for the exact location, and be waiting from 8:30.

You can also meet at the Nicetravel office on Fiskislóð 45M by 8:20 if you arrange that directly with the company. The group size is limited to 19, which gives the vehicle a smaller feel than a large sightseeing coach.

The first listed stop is Glanni Waterfall, with about 30 minutes for sightseeing. This is a useful opening stop because it gets you out into the scenery early, before the longer set of visits. The nearby Norðurá River area has a calm, open feel, and the waterfall gives you a first taste of the region’s powerful water and volcanic terrain.

Half an hour is enough for photographs and a short look, but not for a long walk. Keep your clothing on and your camera accessible. Icelandic weather can change quickly, and you will want warm layers throughout the day.

Deildartunguhver, Iceland’s steaming powerhouse

The stop at Deildartunguhver lasts about 20 minutes. This is a photo stop and a chance to see geothermal water forcing its way up from underground. The hot spring area is visually different from the waterfalls: instead of rushing water, you get steam, heat, and a reminder that Iceland is still shaped by active volcanic forces.

Do not treat this as a bathing stop. Deildartunguhver is a geothermal viewing area, not the warm pool experience some visitors expect from Iceland. The value here is seeing the force of the hot water close up and placing it in the wider story of Iceland’s geology.

A short stop works well because the day has several major sights ahead. Your guide may add local context, but the level of commentary can vary. Several guides have been praised for humor, stories, and clear explanations, while one visitor found a guide more like a driver than a storyteller. That is worth keeping in mind if guiding style matters greatly to you.

Reykholt and Snorralaug’s medieval connection

Reykholt gives the tour a change of pace. You have about 30 minutes to visit the historic site, see Snorralaug, and take photographs.

Snorralaug is a small hot spring associated with Snorri Sturluson, the famous Icelandic poet and political figure who lived in the medieval period. Written sources connect the pool with his bathing, and that small detail makes the site feel personal. You are not just looking at an old building or a sign. You are seeing a place tied to a real person whose writing shaped much of what the world knows about Iceland’s saga age.

The time here is brief, so do not expect a full museum visit or an extended history lesson. Instead, think of Reykholt as a compact cultural stop that gives meaning to the region. Borgarfjörður is often linked with the Icelandic sagas, and this is where the route makes that connection most clearly.

I particularly like this stop because it keeps the day from becoming a parade of scenic viewpoints. The volcanic sights are impressive, but Reykholt reminds you that people have lived with these hot springs, rivers, and lava fields for centuries.

Hraunfossar and Barnafoss: the scenic center of the day

The tour allows about 1.5 hours at Hraunfossar, including free time, photographs, lunch, and sightseeing. This is the longest above-ground stop and, for many people, the visual high point.

Hraunfossar is not one single waterfall dropping from a cliff. Instead, countless streams appear from the Hallmundarhraun lava field and run toward the river. The falls stretch for roughly 900 meters, so you can view the scene from more than one point. The water, fed by the area around Langjökull, often contrasts beautifully with the dark volcanic rock.

A few minutes away is Barnafoss, a faster and more concentrated waterfall. Having both close together gives you two different views of moving water. Hraunfossar feels broad and spread out, while Barnafoss has more force and movement.

You have enough time for photographs and a proper pause, but lunch is your responsibility. Meals are not included, so bring cash. The schedule includes a lunch stop, and there is also a coffee break later in the day. I would bring a packed snack as well, especially if you have dietary needs or do not want to rely on whatever is available at the stop.

Weather can change the feel of Hraunfossar. In clear conditions, the color of the water and the long line of falls are easy to appreciate. In rain or snow, the paths and viewing areas may feel less comfortable, but the waterfalls remain worth seeing. Wear a waterproof outer layer and shoes with a good grip.

Entering Viðgelmir, a 1,600-meter lava cave

The cave visit is the reason I would choose this tour over a basic waterfall outing. Viðgelmir is just under 1,600 meters long and contains lava formations and changing colors formed as molten rock moved through the ground and cooled.

The guided visit lasts about 1.5 hours. Admission is included, and a specialist cave guide leads the underground portion. The cave guides have been praised for strong geology explanations and careful attention to safety. One guide, Erin, was singled out for an informative presentation, while another visitor described the guide as an excellent geologist who explained the formation in detail.

Inside, expect a wooden walkway, handrails, and wet conditions. Water can drip from above, and the surface may be slippery. The cave is not a casual stroll in ordinary shoes, so wear warm clothing and sturdy footwear. The temperature underground can feel very different from the conditions outside.

The formations can be striking, with colors, rough lava textures, and ice shapes in colder weather. Winter may bring ice formations created by water dripping through the cave. These can add a magical quality, but winter weather also makes the journey more demanding above ground.

You should also be realistic about access. The cave visit is not suitable for wheelchair users or people with mobility impairments. Children under five are not accepted. If someone in your group has difficulty walking, the area near the cave entrance has a café with views over the lava flow, but you should confirm the arrangements with the operator before booking.

The cave shows Iceland’s volcanic power in a way a distant mountain never can. You are walking through the path of an eruption, looking at the cooled remains from inside. That makes the experience more than a photo stop.

Húsafell and the return to Reykjavík

The final listed stop is Húsafell, with about 30 minutes for a break, a visit, or shopping. This gives you time to stretch, use facilities, or pick up something before the drive back.

It is a useful pause after the cave. The day has included walking, underground paths, photographs, and several transfers, so a short break matters. Do not expect a major attraction here. It functions more as a comfortable stop before the return journey.

The bus has free Wi-Fi, which is handy for checking messages or sharing photographs, though I would not count on using the ride as a full workday. The drive back to Reykjavík completes a day of up to 10 hours, so keep your evening plans light.

Guides, group size, and the feel of the day

The guide can shape this experience. Names mentioned by past participants include Filip, Walter, Colin, Addi, David, Thor, and Nicole, but your guide will depend on the date. Filip was praised for his stories and music selection, Walter for humor and warmth, Colin for handling difficult snowy weather, and David and Thor for being friendly and entertaining.

The cave guide is separate from the main driver-guide. That is important because the underground section has its own specialist briefing and explanation. The main guide’s approach may range from lively storytelling to a more practical driving-and-directions style.

With no more than 19 passengers, you should have a better chance to ask questions and hear the guide than on a large coach. Small groups also make pickup and movement between stops easier. The tradeoff is that the day still follows a set schedule. You will not have unlimited time at any one waterfall or historic site.

Who should book this tour?

I would choose this tour if you want a full West Iceland day without renting a car. It is especially good for you if waterfalls, volcanic geology, and Icelandic history all matter, rather than only one of those themes.

It also suits first-time visitors who want strong variety in one outing. Hraunfossar gives you broad water views, Deildartunguhver brings geothermal heat, Reykholt adds medieval culture, and Viðgelmir supplies the memorable underground section.

You should think twice if you have limited mobility, dislike wet walking surfaces, or want a slow day with long breaks. The cave requires walking, the schedule is full, and lunch is not included. Families with very young children should note the minimum age of five.

The cancellation policy is practical: you can cancel up to 24 hours ahead for a full refund, and you can reserve now and pay later. That helps if your Iceland schedule may shift, but the real decision is whether you are comfortable giving a full day to a structured route.

Final verdict: a strong choice for West Iceland

I would book this tour for its combination of Viðgelmir Lava Cave and Hraunfossar. Either one could justify a trip beyond Reykjavík, but seeing both in one day gives the outing real value.

Choose it if you want expert cave guidance, a small group, saga history at Reykholt, and a wide sample of West Iceland’s volcanic character. Skip it if you want a short excursion, a bathing-focused hot spring tour, or a route designed around complete independence. For most visitors with one free day and a reasonable ability to walk, this is a well-balanced and memorable way to see the west.
