Reykjanes goes underground on purpose. This small-group day tour is built for the volcanic side of Iceland most visitors skip, with lava tube time, geothermal color, and a more off-the-main-road feel. You start early, you get picked up, and you spend the day with a guide who talks volcanoes like they’re old friends.

What I like most is how small it is (max 4), so you’re not lost in a crowd. I also like that the guide work is adaptive—on days with crazy wind or shifting storms, the plan can flex to keep you moving and keep the best sights in reach, with Damian and Premmi leading the way. The main drawback? This is not a sit-and-sip outing. You need heavy duty layers and a moderate fitness level, because there’s underground walking and some scrambly, active segments.

Key things to know before you go

• Max 4 travelers means a calmer pace and more time to ask questions.
• Leiðarendi lava tube is the big-ticket stop, with colorful formations from separate eruptions.
• Reykjanes “secret spots” aim you away from the usual busy approach routes.
• Blue Lagoon area, but not just the postcard: you’ll see defensive dirt walls and geothermal power-plant elements.
• Weather can change fast, so pack for sleet, wind, and sudden cold.
• Comfortable hiking shoes and gloves help a lot when the ground is slick and cold.

Why Reykjanes Secret G Spots feels different

Reykjanes is Iceland’s volcanic “entryway,” but most trip plans only glance at it on the way to somewhere else. This tour spends real time here—below ground and around geothermal activity—so you actually understand what you’re looking at.

The other thing that makes it work is the vibe. With a maximum of 4 people, the day feels closer to a private field outing than a bus tour. You’ll get a tighter route, more direct guidance, and less waiting around for everyone to catch up.

Start time is 8:30 am, and the official duration is about 8–9 hours. In real life, Iceland weather and road conditions can stretch the day, so plan as if it could run closer to a full day. If that makes you nervous, you’ll want to avoid booking this when you can’t spare a long chunk of time.

Leiðarendi Cave: colorful lava tube time underground

Leiðarendi Cave is the headliner, and it’s not a quick photo stop. You’ll go underground for about 2 hours and see a lava tube system with incredibly colorful walls. The formations are tied to eruptions that happened around 2000 years ago and roughly 1000 years ago (two separate events that shaped different parts of the cave).

This is where the tour earns its raw edge. In one standout account of the trip, the route included a narrower, scrambly section that led you through wilder cave areas before entering a more frequently visited section near the main entrance. That kind of routing matters because it changes the feel: you’re not just doing the most obvious trail, you’re experiencing the cave as a living volcanic structure.

Practical reality check: caves are cool, and the ground can be uneven. If you’re short on balance skills or you hate confined spaces, you may find the underground parts demanding. The tour’s guidance is built around safety, and a speleology-focused team like Damian and Premmi tends to explain what you’re seeing as you go—so you don’t just get wet-rock visuals, you get meaning.

Kleifarvatn Lake: a quick break with monster stories

After the cave, you get a short stop at Kleifarvatn Lake for about 30 minutes. This is a classic Iceland trick: make a fast pause feel memorable. You’ll take in the views at an Iceland version of a Loch Ness-style setting—there are local monster stories wrapped around the lake’s reputation.

The benefit of this stop isn’t that it’s long. It’s that it breaks the day up after underground time and keeps your route moving through the Reykjanes region. If you’re traveling with someone who wants variety—lava first, then geothermal, then lake scenery—this short detour helps.

Wear the same cave-and-weather mindset here. Wind and cold can make a scenic spot feel exposed. Bring gloves even if you think you only need them underground.

Seltún geothermal area: mud pools and hot steam in tight time

Next comes Seltún Geothermal Area for about 30 minutes. This stop is built for quick impact. You’ll see mud pools, hot springs, and steaming ground with a wide range of colors—exactly the kind of place where your eyes struggle to believe the stuff you’re watching.

Why it’s worth the time: geothermal areas can look similar from far away, but up close you start noticing how the ground textures change, how steam moves, and how the heat signatures create different surface colors. With a guide who’s paid attention to volcanic processes (Damian and Premmi are both described with speleology experience), you get explanations that connect the visual details to what’s happening underground.

The drawback is also simple: the stop is short. If you want 90 minutes of wandering, this may feel like a taste. But for most people, the pacing is a strength. It keeps your day active without dragging you through multiple long transfers in harsh weather.

Blue Lagoon area: hike on top, then the lagoon with the power-plant angle

The Blue Lagoon portion comes in two parts.

First, you’ll hike on top and admire the steamy volcanic features described as tied to the Reykjanes fires eruption in the 13th century. This is about 1 hour, and the admission ticket for this part is listed as not included. Even if you don’t plan to swim, this timing works because it lets you experience the area from a viewpoint without instantly turning the day into a ticket-and-locker scramble.

Second, you’ll return for another Blue Lagoon stop of about 30 minutes, with an admission ticket listed as free for that segment. Here, you’ll see the huge dirt walls that help defend the area, plus geothermal power-plant elements. One account also mentioned getting close to a bore hole for the Blue Lagoon geothermal power plant, which is a big deal if you like the “how Iceland works” side of things.

A heads-up on costs: since one Blue Lagoon part is listed as not included and another is listed as free, treat the lagoon budget as something you should confirm for your exact interests. If you want the full inside-the-lagoon experience with all facilities, you’ll likely need extra planning. If you mainly want steam, volcanic activity, and the industrial-meets-nature context, this tour’s approach can feel like strong value.

What the day feels like: active touring, shifting weather, and smart reroutes

This is an active day. The tour calls for moderate physical fitness, and the practical guidance you should take seriously is the clothing advice: heavy duty gear, hiking shoes, and weatherproof layers.

One of the strongest reminders from an account of the day: the weather can change dramatically—wind, snow, sun, rain, sleet, and hail all within short stretches. The guide tailored the day around that, switching to alternative locations and keeping the group moving. That’s not just luck; it’s what makes a small-group format work. When you’re not stuck with a fixed script and a giant schedule, the guide can use real-time judgment.

My practical suggestion: pack like you expect cold plus wet plus wind. Gloves help. A hat helps. Waterproof everything helps. If you dress for just one weather type, Iceland will test your wardrobe.

Pace tip: the tour runs long enough that dinner plans should be flexible. After a day mixing underground exploration and geothermal stops, you’ll probably want an easy night.

Pickup and small-group logistics that actually matter

Pickup is offered in many areas: Reykjavik, Grindavik, Vogar, Sandgerdi, Gardur, Keflavik, and Hafnir. That’s a big time-saver. It also makes the tour feel easier if you don’t want to wrestle with finding the right meeting point while you’re still getting your bearings in Iceland.

The vehicle note isn’t something you can control, but it’s worth knowing that one group’s 4×4 was in repair and they were picked up in a different vehicle than expected. The guide handled it, apologized, and still delivered the same core locations plus extra. In plain terms: Iceland logistics can throw curveballs, but the service is described as responsive when problems show up.

The maximum group size is 4 travelers, and that small number affects everything: quieter drives, more time at stops, and a tour that feels more like a guided day with specialists than a scripted conveyor.

Price and value: is $270 per person a good deal?

At $270 per person, you’re paying for a guided, active day with small-group access and multiple major stops. The value isn’t only the sights—it’s the structure.

Here’s what that price buys in practical terms:

• Specialized stops: a lava tube experience that takes time (about 2 hours) and isn’t just a quick look.
• Geothermal context: Seltún and the Blue Lagoon-area power-plant angle connect the dots between steam, rock, and energy.
• Tickets included for several segments: Leiðarendi Cave, Kleifarvatn Lake, and Seltún are listed with free admission tickets, and one Blue Lagoon segment is also listed as free.
• A low headcount: max 4 people means you’re not fighting for space, and questions don’t get lost.

What you should watch: the Blue Lagoon part that lists admission ticket not included. If you want the lagoon experience beyond what’s included, budget extra and confirm what you’ll actually get for your ticket.

For people who like off-the-main-road travel and don’t mind active touring, $270 can feel like a fair price. For people who want a laid-back day with minimal walking and zero gear, it can feel high.

Who should book this tour (and who should skip it)

This is a great match if you:

• Want more Iceland than the usual highlights
• Like geology and want explanations tied to what you’re seeing
• Are comfortable with hiking shoes, layers, and cold conditions
• Prefer small group energy and direct interaction with the guide

You might want to skip (or book only if you’re very comfortable) if you:

• Hate cramped or uneven walking, including underground cave movement
• Don’t do well with sudden weather changes
• Need a low-activity day with lots of sitting time

The tour is described as suitable for a family group from ages 13 to 53 in one account, which suggests the activity can work across a wide range—so long as you’re willing to dress and move.

Should you book Reykjanes Secret G Spots (raw edition)?

If you’re in Iceland for a short time and you want your day to feel like it belongs to you instead of to the crowd schedule, I’d book this. The combination of a real lava tube experience, geothermal color at Seltún, and the Blue Lagoon-area look at walls and the power plant angle creates a stronger “I get Iceland now” feeling than most one-day overviews.

Book it especially if you care about going beyond the usual route and you’re okay with an active day in cold weather. If weather frightens you, remember the tour depends on good conditions, and plans can shift for safety and access—so your best move is to pack well and keep your expectations realistic for Iceland.
