Lava tubes under Reykjavík change your perspective. This 8–9 hour small-group outing (max 4 people) takes you off the main routes to see Leiðarendi Cave and the Seltún geothermal area, plus quieter stops around Reykjanes. It’s a day built around geology you can actually feel, not just read about.

I especially like the intimate group size and the way the guide keeps the day practical and personal. With guides such as Damian (and support from Premmi), the explanations stay grounded in what you’re standing in front of—plus the route can shift when weather turns chaotic, which matters a lot on Reykjanes.

One consideration: this is physically active. Expect heavy-duty layers, good grip shoes, and moments that feel more like crawling in a lava system than strolling a viewpoint, and the day depends on decent weather.

Key takeaways before you go

• Leiðarendi Cave’s lava-tube contrasts: you’ll see sections that feel wilder before moving into more standard areas.
• Real guide talk: you get clear explanations tied to what formed the rock and why the colors differ.
• Short geothermal hits: mud pools, hot springs, and steaming ground in tight, memorable bursts.
• Blue Lagoon area without the usual crowd rush: you’ll focus on the steam, defenses, and nearby geothermal power plant setup.
• Max 4 people: more hands-on pacing, more questions, less waiting around.

Why Reykjanes G Spots feels like a side-door into Iceland

Reykjanes is where Iceland shows its work. Instead of just distant volcano views, you get close to the plumbing: lava tubes underground, geothermal heat bubbling at the surface, and volcanic leftovers that still look fresh.

What makes this tour different is the tone. It’s built for people who want geology with texture—steam, rock, heat, and the odd shapes that form when Earth keeps moving.

Price and what you actually get for $270

At $270 per person, you’re paying for three big things: transportation with pickup, a small group, and guided access to multiple sites. Many tours in Iceland either go cheap and crowded or go small and skip the harder-to-reach pieces. This one tries to do both—so you pay more, but you also get fewer people and more time with the guide.

Admissions are partly covered. The cave stop and the lake/geothermal stops list admission tickets free, while the Blue Lagoon segment specifically notes that admission is not included for one part of the day.

The value also comes from how the day is handled. One review-style theme stands out: the guide adapts when weather swings fast, and that can be the difference between a forgettable route and a great day off the highway.

Pickup, timing, and how early your day really starts

The tour starts at 8:30 am. That early departure is a gift, because Reykjanes weather can build quickly, and you’ll want daylight when you’re under ground or walking near geothermal areas.

Pickup is offered across the Reykjavík area and beyond, including Reykjavik, Grindavík, Vogar, Sandgerði, Garður, Keflavík, and Hafnir. You’ll also get a mobile ticket, which keeps check-in simple and reduces faff.

Expect the day to feel full. The listed duration is 8–9 hours, but the outing can run like a proper adventure day, especially if the guide has to reshuffle timings due to winds or precipitation.

Leiðarendi Cave: colorful lava tubes and the crawl-ready reality

Leiðarendi Cave is the star for most people because it’s physical. You’re going underground into a lava tube system with colorful formations linked to eruptions that happened roughly 2000 years ago and 1000 years ago.

The best part is the feeling of stepping into two different ages of volcanic activity. One guide-driven detail that comes through strongly in descriptions of this tour: the route can include a narrow, scrambly section that leads to wilder, less-farmed-feeling cave before you enter areas closer to the main entrance.

If you’re picturing a dry, easy show cave, adjust that expectation. Reviews mention crawling and squeezing, and the trip works best if you’re comfortable with uneven ground and tight spaces. You don’t need to be a pro spelunker, but you do need to be ready for “adventure mode.”

Practical note: bring the right footwear. If your shoes slip on wet rock, the cave stops being fun fast. Plan for grips and stable soles, not just comfort.

Kleifarvatn Lake: myth stories, real geothermal context

Kleifarvatn Lake is a short stop—about 30 minutes—but it earns its place. This area is tied to the Reykjanes system, and the tour frames it with the kind of context that makes local stories land.

You’ll hear the lake described like an Icelandic version of the Loch Ness idea, complete with the monster folklore. The point isn’t to test the legend. The point is to connect why this particular setting inspires stories: still water, dramatic ground, and an environment shaped by heat and volcanic history.

For your timing: since this is a quick stop, use it to reset. Grab photos, look at the surroundings, and get back ready for the geothermal steam later.

Seltún geothermal: mud pots, hot springs, and fast color changes

Next comes Seltún Geothermal Area, again about 30 minutes. This is where Reykjanes hits you with color and texture: mud pools, hot springs, and steaming ground showing a wide range of hues.

What you’re seeing isn’t just pretty. Different colors often track different minerals and heat interactions. The steam, the wetness, and the ground’s behavior make the explanation stick in a way a textbook never does.

A short caution: geothermal areas look stable, but they aren’t. You’re visiting places that steam and bubble, so move carefully and follow the guide’s instructions on where to step.

This is also the kind of stop where your clothing matters. If you arrive underdressed, the cold wind plus wet steam can make the 30 minutes feel longer than it should.

Blue Lagoon area: steam, a XIII-century eruption link, and the power-plant view

The Blue Lagoon segment has two parts in the flow of the day. One part involves hiking on top to admire the “mystic steamy creater” linked to the Reykjanes Fires eruption in the 13th century. The other part focuses on the Blue Lagoon area’s defenses—walls and infrastructure—plus nearby geothermal power-plant context.

The main thing to understand is ticket coverage. One Blue Lagoon stop notes admission not included, while another segment lists admission free. That means you should plan for the possibility that you won’t have full Blue Lagoon entry included for the day, depending on which access you’re expecting.

What you’ll get instead is a more geology-forward look at why this place is special. You’ll see the built defenses around the lagoon and get context for the geothermal system running nearby, which is the value-add if you’ve already seen plenty of “sit in water and take photos” versions of geothermal tourism.

Also: if you’re chasing the vibe of the Blue Lagoon but want the science, this is the better-fit option.

Weather swings are part of the deal—here’s how to handle it

Reykjanes weather can change fast. One account describes winds, snow, sun, rain, sleet, and hail in a single day, with the guide tailoring the plan based on conditions and preferences.

That adaptability is exactly why a guided small-group day works better than DIY. Iceland isn’t just cold; it’s changeable. If visibility drops, access rules shift, and trails around geothermal areas can get slick.

Your best move is to dress like the weather will misbehave—because it might. Bring waterproof layers, gloves, a hat, and shoes with grip. Reviews emphasize heavy-duty clothing and comfort for a physically active day, and that matches what this route asks of you.

Getting close enough to photograph heat and rock

A strong theme in the descriptions: you can get close. Not reckless-close—guided-close where safety rules still apply. The payoff is photos that show scale and texture, not just “guess where the volcano is” shots.

In particular, one review highlights getting close enough for great pics and video tied to volcanic activity. Another description emphasizes the emotional side: feeling the heat near lava and seeing fresh pathways where lava systems shifted.

Even if you don’t care about extreme geology, this closeness helps you understand the island. Iceland stops being a postcard and starts acting like a living system.

The guide matters: Damian, Premmi, and real adaptation

This tour’s quality shows in the guidance. Damian is mentioned as very informative and pleasant, with a passion for explaining the forces behind Iceland. Premmi is also mentioned as part of the guiding team, with a speleology background that shows in how the cave experience is handled.

Here’s what that means for you: the explanations aren’t random facts. They’re timed to what you can see, so you make sense of things like layered volcanic history and how geothermal zones behave.

It also helps when weather goes sideways. When plans change, you still get the day’s themes—lava tubes, geothermal power and steam, and volcanic terrain—rather than a shortcut to a busy viewpoint.

What to wear and bring so you stay comfortable (and safe)

This is not a light outing. It’s built for people with moderate physical fitness, and the day can include hiking and hands-and-knees moments. Bring hiking shoes or boots with grip.

Your clothing checklist should be simple:

• waterproof layers (top and bottom)
• gloves and hat
• extra layers in case wind cuts through
• gear that tolerates getting damp

If you show up in fashion shoes or thin rain gear, the experience becomes stressful. Dress for the ground you’ll step on and the steam you’ll stand near.

Who this tour is best for (and who should reconsider)

This tour fits you if you want:

• a small group day with time to ask questions
• an active cave experience, not just a bus stop photo
• geothermal sights with real explanations
• a guide who adapts based on weather

It might be less suitable if you’re looking for a fully relaxed, wheelchair-friendly style day. The tour does require moderate fitness and heavy-duty clothing, and the cave segment is the main reason why.

If you’re traveling with a wide age range, it’s still possible to enjoy it—as long as everyone can handle uneven ground, damp conditions, and the pace set by the guide.

Should you book Reykjanes Secret G Spots – Raw Edition?

I’d book this if you’re the type who gets more excited by heat, rock, and process than by crowds and gift shops. The combination of a cave-focused main event, quick but intense geothermal stops, and a Blue Lagoon-area look that’s tied to infrastructure makes it feel like a smarter way to experience Reykjanes.

Choose it if you want value from attention, not from quantity. Max 4 people, pickup coverage, and guided context make the higher price easier to justify. The biggest risk isn’t the tour itself—it’s weather and your willingness to dress for it and move a bit.

If you want to see Reykjanes’s less touristy side with guides like Damian and Premmi guiding you through real volcanic features, this is a strong match.
