Reykjanes secret G spots – raw edition
Caves and geothermal oddities, far from the crowds. This small-group Reykjanes route sends you into the lava tube world of Leidarendi, then loops through lakes and steaming ground, with a guide who can explain what you are actually seeing. I like that the small-group size (max 4) keeps things flexible, even when Iceland serves wind, sleet, and rain.
Stop one is about two hours underground in colourful passages shaped by two ancient eruptions, and having experts like Damian (and Premmi) around makes the day click, not just photograph. The only real drawback is the effort: you need moderate fitness, and you should pack heavy-duty waterproof clothing because this is a real hike and cave day.

Key moments at a glance

- Leidarendi lava tube time (about 2 hours): A proper underground visit, with colourful formations tied to eruptions around 2000 and 1000 years ago.
- Kleifarvatn lake stop (about 30 minutes): A scenic geothermal lake with a Scottish Loch Ness-style monster legend vibe.
- Seltún geothermal area (about 30 minutes): Mud pools, hot springs, and steaming ground with a wide range of colours.
- Blue Lagoon pair of stops: A hike on top first (Blue Lagoon admission not included for this part), then a second stop focused on the lagoon area and protective dirt walls near the power plant.
- Max 4 people, English guide: More conversation, calmer pacing, and better chances of adapting when weather changes fast.
Reykjanes, the part of Iceland most people skip

Most Iceland trips race along the highway and hit the biggest stops in the easiest order. This one points you toward Reykjanes, the volcanic peninsula where the scenery is dramatic, but often missed because it is farther off the main tourist circuit.
The big value is the format. You start at 8:30 am, and you get pickup from Reykjavik and nearby towns including Grindavik, Vogar, Sandgerdi, Gardur, Keflavik, and Hafnir. That matters in Iceland, where parking, timing, and weather can turn small hassles into big ones. You also go with a tiny group, capped at 4 travelers, so you are not stuck waiting on a crowd to move between stops.
At $270 per person, this is not a bargain-price tour. But the cost starts to make sense when you see what is included: multiple stops list admission as free and your guide is actively driving the day, not just reciting facts. If you want Iceland that feels personal and a little rough around the edges, this fits.
Leidarendi lava cave: your first wow, and it is truly underground
Your day begins underground at Leidarendi Cave. Plan for about 2 hours here, and expect colourful lava tube scenery formed by two separate eruptions, around 2000 and 1000 years ago.
What makes this stop special is how different it feels from the usual Iceland postcard. You are not just looking at rock, you are walking through it, in spaces that highlight how lava moves and cools. The tour is also built around a guide who can explain the forces at work, which makes the cave feel less like a random detour and more like a lesson you can walk through.
Practical considerations:
- Bring hiking shoes or boots. The cave experience is not described as a stroll, and Iceland conditions outside can be messy too.
- Dress for cold and damp. Even when the Iceland weather outside is decent, underground spaces can feel cool.
- Expect a bit of crawling or squeezing. One of the standout themes from the day is that it is not a sit-back sightseeing walk.
This is the stop that most people remember, and it is where the tour earns its reputation for taking you to places off the typical route.

Kleifarvatn and Seltún: short stops, strong geothermal personality

After the cave, the pace shifts toward geothermal variety. First comes Kleifarvatn Lake. You get about 30 minutes, and the reason it is fun is not only the view. It is the mood and the story. The lake has an Icelandic monster legend that gets compared to the Loch Ness style myth, which adds a playful layer to a very real-looking geothermal setting.
Then you head to Seltún Geothermal Area for another 30 minutes. Here, you are in mud pools, hot springs, and steaming ground, with colours that come from the mix of minerals and heat. Seltún is the kind of place where your eyes keep adjusting. One minute it looks like scorched earth. The next it looks painted by minerals you did not know existed.
The tradeoff with these stops is time. Thirty minutes goes fast when weather changes or you are stopping to really look. But that is also why they work in a half-day rhythm. You get variety without burning hours in one spot.
Both of these stops list admission as free, which is a nice way to keep the day feeling like value, not like an endless ticket line.
Blue Lagoon, but with a volcanic brain

Blue Lagoon is the part where you need to pay attention. The tour gives you two different Blue Lagoon moments.
First, you get a 1-hour hike connected to the volcanic activity in the area, described as a steamy crater created during the Reykjanes fires eruption in the 13th century. For this part, Blue Lagoon admission is not included. That does not mean you are left out entirely, but it does mean you should confirm what ticket or access is required for the exact Blue Lagoon area you will be using.
Second, there is a later stop at Blue Lagoon for about 30 minutes, and this time the listing says admission is free. This stop is framed around what is less obvious than the water itself: the huge dirt walls that help defend the lagoon, plus the nearby power plant connection.
In plain terms, you get the Blue Lagoon experience, but through a volcanic and infrastructure lens, not just a float-and-pose lens. If you like learning how places work, you will appreciate this. If you only care about soaking in warm water, you might find that the time allocation is better for exploring than for long lounging.
Damian and Premmi: expert talk, safety-first pacing

A huge reason this tour gets such a strong response is the human factor. The guide Damian is repeatedly described as informative and pleasant, and the day is also linked to Premmi, with both showing a speleology and Iceland science mindset.
What that means for you on the ground:
- The cave and geothermal stops are not treated like quick photo stops.
- You get context that helps you interpret colours, formations, and heat patterns.
- The guide keeps safety as the priority, especially for cave sections and any scrambling.
This kind of guiding is also why weather flexibility matters here. Iceland weather can change fast. One person noted the day included winds, snow, sun, rain, sleet, and hail, and the guide adjusted the plan to match the group and the conditions. You should not assume every day will run like that, but you should assume the route can shift for safety and comfort.
There is one more practical angle: small groups reduce friction. You are not waiting for a bus load. If something needs changing, the group can usually adapt quickly.
Next clear spell around Reykjavik could go to:
What you actually do all day, and how hard it is

This is a moderate physical fitness outing, and it is smart to treat it like an active day rather than a light stroll. The tour includes:
- An underground experience at a lava tube (about 2 hours)
- Multiple geothermal viewpoints (each about 30 minutes)
- A hike connected to the Blue Lagoon area (about 1 hour)
So yes, it involves walking, uneven ground at times, and cold weather gear. Iceland is not forgiving if you arrive in the wrong clothes.
Pack like you are going into wind and wet:
- Hiking shoes (not just sneakers)
- Heavy-duty clothing
- Layers and waterproof outerwear
- Gloves and a hat can be a lifesaver, especially in cave areas and on open ground
If you are comfortable moving in and out of uneven cave spaces and you can handle changing weather, you will enjoy this much more.
Price, value, and what can change your total cost

Let us talk numbers without pretending this is cheap or pretending it is a scam.
The base price is $270 per person for a trip listed at 8 to 9 hours. Your value comes from a few places at once:
- Pickup from Reykjavik and several nearby towns
- Small group size (max 4 travelers)
- Multiple stops with free admission listed (Leidarendi, Kleifarvatn, Seltún, plus one Blue Lagoon stop)
- A guide who brings real context, especially for the cave
What can affect your final out-of-pocket cost is Blue Lagoon. The schedule shows one Blue Lagoon moment where admission is not included. So you should be ready for the possibility of a separate ticket cost depending on exactly what access you will use on that hike segment.
Also, plan for time. The tour duration is listed as 8 to 9 hours, but the day can feel longer because weather can change and because cave time and hiking take stamina. I recommend treating it like a full-day commitment and not planning anything fancy the same night.
Who should book this Reykjanes secret tour

This tour is best if you want:
- Iceland that stays off the highway and away from the biggest crowds
- A small-group day with real conversation
- Volcanic sights that go beyond the quick surface-level stop
- An active mindset for caves, geothermal ground, and a hike
It may not be the right fit if you:
- Want only easy, paved walking
- Hate tight or enclosed spaces
- Are not comfortable with cold and wet conditions, even with good clothing
- Want a pure soak-and-relax Blue Lagoon schedule
If you enjoy learning, and you like feeling like you are in the hands of a real specialist for volcanic terrain, this fits the bill.
Should you book Reykjanes secret G spots, raw edition?
I would book it if your idea of a great day in Iceland is going past the postcard version and getting hands-on with lava and geothermal energy, with a guide like Damian and Premmi who can explain the why behind what you see.
If your travel style is more relaxed and you want minimal walking, you might find the cave and hike demanding. In that case, it is better to choose something with less physical movement.
My final advice is simple: check your footwear and your weather gear. Then go. This is the kind of tour where the most memorable moments happen because you are willing to step into colder, stranger spaces.
