Iceland’s best cave experiences are not always the easiest ones to reach. This private trip takes you far into the lava fields near Borgarnes, then asks you to walk for about 45 minutes over rough ground before you reach a remote lava tube. Inside, you’ll have roughly two hours to study volcanic rock, lava formations, stalactites, stalagmites, and the rare glass strands called Pele’s hair. I like the remote setting and the fact that your own guide can shape the pace for your group.

I also like the private transport and flexible pickup, which can be arranged from Reykjavik, the airport, or a cruise terminal. Thomas from EV Travel receives especially strong praise for careful planning, flexibility, and his work as a guide. The catch is simple: this is a long day with four hours of driving, a rough hike, and no included lunch. You need solid footwear, warm clothing, and a moderate level of fitness.

Key points at a glance

Lava Tunnel & Caving Adventure - Key points at a glance

  • A remote lava cave near Borgarnes: Reach the cave by walking about 45 minutes through rough volcanic ground.
  • Two hours underground: Explore lava tubes, caves, volcanic formations, stalactites, stalagmites, and possible Pele’s hair.
  • Private group of up to five: Your party travels alone with a dedicated driver guide.
  • Pickup from several locations: Collection is available in Reykjavik, at the airport, or at a cruise terminal.
  • A possible wild hot spring stop: Bring a towel, but expect no toilets, changing rooms, or formal bathing facilities.
  • A full eight-hour day: The tour includes about two hours each way on the road, plus the hike and cave visit.

Reaching the lava fields from Reykjavik

The day begins at 8:30 a.m. with pickup at a location you choose. That may be your accommodation in Reykjavik, the airport, or a cruise terminal. If your exact pickup point is unclear, you can select a nearby place and contact EV Travel to arrange the final details.

The drive to the cave area takes about two hours. That is a large part of the day, but it also explains why this outing feels different from a quick attraction near the city. You are heading away from the usual Reykjavik circuit and toward volcanic ground where the cave is known to relatively few people.

A short restroom stop is planned along the way. You can also buy lunch or snacks at this point, which matters because lunch is not included. Snacks and bottled water are supplied, but I would still plan your food before setting out. An eight-hour day with a hike and cave work is not the time to rely on a small snack alone.

The vehicle is air-conditioned, privately used for your group, and fitted with Wi-Fi. Those details are useful on the long road sections. With a group of two to five people, the private setup also gives you more room to talk with your guide, ask questions, or adjust the day within the available schedule.

The 45-minute walk to a remote cave

Lava Tunnel & Caving Adventure - The 45-minute walk to a remote cave

Once you reach the site, the cave is not right beside the vehicle. You walk for around 45 minutes through rough terrain. This approach is one of the reasons the outing feels more like an adventure than a standard sightseeing stop, but it is also the main physical test before the underground section begins.

You should be comfortable walking on uneven volcanic ground. Good hiking boots or sturdy walking shoes are essential, and they are not supplied. Iceland’s weather can shift quickly, so bring a warm layer, hat, and gloves as well. The tour specifically asks for a moderate level of fitness, and that is a fair description of the day.

The walk gives you time to notice the volcanic setting before entering the cave. The route passes through lava fields and among dark volcanic rock formations. You may find the approach as memorable as the cave itself, especially if you enjoy seeing how the ground changes after an eruption.

This is not the right choice if you need a smooth path, a short walk, or an easy sightseeing stop. The experience depends on getting into a remote place under your own power. For anyone who likes a little effort in exchange for a quieter setting, the hike is part of the value.

Two hours among Iceland’s lava tubes

Lava Tunnel & Caving Adventure - Two hours among Iceland’s lava tubes

At the cave, you put on the provided caving equipment before going underground. The roughly two-hour exploration gives you time to look closely at the lava tube and learn how its shapes formed.

Lava tunnels develop when the outside of a flowing lava stream cools and hardens while hotter lava continues moving inside. When the flow ends, it can leave a hollow passage. In this cave, you can expect to see the results of volcanic activity in several forms, including lava tubes, caves, rough volcanic rock, stalactites, and stalagmites.

The most unusual feature may be Pele’s hair, also called lava hair. These are long, delicate strands of volcanic glass created during an eruption. They can be easy to miss, so having a guide point them out adds real value. This is not just a walk through a dark hole. It is a chance to understand small details of Icelandic geology that you might otherwise pass without noticing.

A private guide also changes the feel of the visit. Your group is not combined with strangers, and the activity is limited to your party of up to five. That makes it easier to ask questions, stop for a closer look, or work at a pace that suits your group, within the guide’s safety instructions.

The cave section is the heart of the experience, but you should keep your expectations practical. This is an active caving trip, not a polished attraction with built paths, bright lighting, or indoor facilities. The rough access and included safety equipment are part of what makes the setting feel genuine. They also mean you should be ready for a more physical and less predictable outing.

What the private format is worth

Lava Tunnel & Caving Adventure - What the private format is worth

The price is $1,316 per group of up to five people, not per person. For a full group, that works out to about $263 per person before any extra food purchases. For two people, the cost per person is much higher, so the value depends heavily on how many are in your party.

That price includes private transportation, a dedicated driver guide, caving equipment, snacks, bottled water, Wi-Fi, fees, and taxes. Pickup is also included, which saves you from arranging a rental car or finding your way to a separate meeting point.

I think the private format makes the most sense for a family or small group that wants a quieter day and direct attention from one guide. It is less compelling for a solo visitor or a pair focused only on keeping costs low. The four hours of road time also make the price easier to assess. You are paying not just for entry to a cave, but for transport to a remote site, a guide, equipment, and an entire private day.

EV Travel plants one tree for every tour taken. That does not change the physical experience, but it is a useful extra for anyone who prefers to support an operator with a stated environmental action.

Same rush, a different way to get it:

The optional wild hot spring on the return

Lava Tunnel & Caving Adventure - The optional wild hot spring on the return

After the cave, the trip returns toward Reykjavik, with the possibility of stopping at a secret hot spring. This is an optional-sounding addition, and it comes with very basic conditions.

Bring a towel if you hope to bathe. The spring has no toilets or changing rooms, so you would need to change outdoors. That may be part of the appeal for some people, but it will not suit everyone, particularly if the weather is cold or you prefer easy facilities.

The stop is best viewed as a bonus rather than the main reason to book. The lava cave is the fixed focus of the day. If the spring visit happens, it adds a wild bathing experience to the return journey, but you should be prepared for the lack of privacy and services.

Ask your guide about the timing and practical details on the day. The overall tour lasts about eight hours, and the return drive itself takes around two hours. A long stop at the spring could affect how much time remains for the journey back, so the plan may depend on weather, road conditions, and the group’s pace.

Thomas and the guiding style

Lava Tunnel & Caving Adventure - Thomas and the guiding style

Thomas is the guide named in the supplied information, and his work receives the strongest praise. He is described as flexible, careful with planning, and willing to go beyond the basic schedule to help shape a good stay in Iceland.

Those qualities matter on a trip like this. The day includes a remote access walk, changing weather, road travel, and an optional stop with no formal facilities. You want a guide who can explain the geology clearly, keep the group moving safely, and communicate well when conditions require a change.

The tour is offered in English. Because it is private, you can use the time for questions about the cave, the volcanic features, or the areas along the route. That direct contact is a stronger benefit here than it would be on a short, crowded excursion.

The small number of published ratings means you should not treat the perfect score as a complete statistical picture. Still, the praise is consistent on the points that matter most: transport, equipment, planning, flexibility, and Thomas as a guide. I would give those specific strengths more weight than the score alone.

What to pack for an active Iceland day

Lava Tunnel & Caving Adventure - What to pack for an active Iceland day

The tour supplies caving equipment, snacks, and bottled water. You still need to bring the clothing and footwear that make the day safe and comfortable.

Pack:

  • Hiking boots or sturdy walking shoes
  • A warm layer
  • A hat and gloves
  • Lunch or money to buy lunch along the route
  • A towel if you want to use the possible hot spring

Do not assume ordinary city shoes will be enough. The 45-minute approach crosses rough terrain, and the cave itself is not presented as a smooth, built walkway. Warm clothing is equally important because the weather on the surface can change, while the cave may feel cool and damp.

The supplied food is useful, but I would treat it as a supplement rather than a full meal. You get a chance to buy lunch or snacks during the restroom stop, so use it.

Weather, cancellation, and physical demands

Lava Tunnel & Caving Adventure - Weather, cancellation, and physical demands

The experience requires good weather. If poor conditions force cancellation, you can choose another date or receive a full refund. For your own planning, that means leaving some flexibility in your Iceland schedule is wise.

You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations made less than 24 hours before the start are not accepted for a refund, so pay attention to the local cutoff time.

The physical demands are moderate, but the details matter. You walk for about 45 minutes over rough ground, spend around two hours exploring the cave, and sit in the vehicle for about four hours total. The day will suit you if you can manage uneven walking and a long outing without needing frequent formal facilities.

Who should book this cave adventure

I would choose this tour if you want a private Iceland experience that goes beyond the city’s easy-to-reach sights. It is especially suitable for a small group of up to five, families with older children who can handle rough ground, and anyone interested in volcanoes, caves, and unusual geology.

It is also a good fit if you value a guide’s flexibility. Thomas can give your group direct attention, and the private vehicle means you are not tied to a large coach group.

I would think twice if you want a short activity, a low-cost excursion, a gentle walk, or a cave with full visitor facilities. The price is hard to justify for a small party on a tight budget, and lunch is extra. The wild spring stop also requires comfort with changing outdoors.

Should you book the Lava Tunnel and Caving Adventure?

Book it if you want the harder-to-reach side of Iceland and have a full day to spare. The remote cave, private guide, included equipment, and chance to see Pele’s hair give this outing a clear identity. The private format is most valuable when four or five people share the cost.

Before paying, confirm your pickup point, check the weather forecast, and prepare the right shoes and warm layers. Bring lunch money and a towel if the hot spring appeals to you. If you accept the long drive and rough approach, this is a focused, personal way to see Iceland’s volcanic ground with Thomas and EV Travel.
