Geothermal Energy Exhibition Entry Ticket
Steam, valves, and turbine halls, all in one stop. At the Hellisheiði ON Power plant geothermal exhibition in South Iceland, you learn how heat underground becomes electricity and heating, with multimedia displays and a self-paced audio guide. It is built for real learning, not just a quick look-and-walk.
I love the hands-on style of the exhibits, especially the cold water, hot water, and steam valve interactive setup that shows the process in plain language. You also get strong visuals about carbon capture, including a display on carbon sequestration, plus video art that keeps it engaging.
One consideration: you cannot enter the actual power plant for safety and security reasons, so your access is mainly from viewpoints into turbine halls and outdoor observation decks. The good news is you still get serious technical views, just not the inside walk-through you might expect.

Why Hellisheiði makes sense on a southern Iceland day

South Iceland is packed with famous stops, but geothermal power gives you a different kind of wow. Here, you are dealing with the mechanics of a real energy source, not just scenery. The Hellisheiði site is one of the largest single-site geothermal power plant areas on the planet, and the exhibition is designed to explain what that means in everyday terms.
What makes this a smart stop is how many “I get it now” moments you can get in a short visit. The layout pushes you from basic geothermal ideas toward how steam turns into electricity and how the plant manages byproducts. It is also a practical add-on for road-trippers, because it fits cleanly into an average 1 to 2 hour window.
This is especially good if you want something educational without feeling like you are stuck in a classroom. The exhibition mixes visuals, audio, and interactive elements, so you can move at your own pace and still feel like you got something out of it.

Tickets, parking, and setting up your audio

Entry is $21.69 per person for a self-guided visit, roughly 1 to 2 hours. You buy what is essentially an exhibition entry ticket with an included audio tour experience, and that is a big part of the value. If you skip the audio, you will still enjoy the displays, but the audio is where the story gets clearer and more detailed.
You will receive confirmation at the time of booking, and you get a mobile ticket. That is handy if you are juggling reservations on a phone already.
Parking is free at the exhibit, which matters in South Iceland where it is often easiest to keep driving and avoid extra stops. If you are building a round-trip day, this one is low-stress: arrive, park, go in, and you are done when you are done.
Audio guide tip you should plan for
The audio guide is available for download, and you can access it via a WR code found at the front desk or through the ON Geothermal Exhibit app. One practical catch: some visitors found the online instructions confusing, where the website seemed to suggest headphones but really wanted an internet-capable device to download the audio.
So, I recommend you bring:
- A phone or tablet with internet access for the download
- Headphones if you want a cleaner, quieter listen in the exhibition
Also note the experience is offered in English, and most visitors can participate. Service animals are allowed too.
Inside the exhibition: what you actually see and learn

Your main stop is the geothermal exhibition experience at the Hellisheiði power plant site. This is not a guided tour that follows a group with a single narrator. Instead, it is a self-guided walk where you use the audio tour to connect the dots between displays, videos, and interactive features.
As you move through, the best parts are the explanations that translate geothermal energy into an understandable chain of events. The multimedia displays use visuals to connect:
- Heat from the ground
- Water turning to steam
- Steam and the turbine process
- How the plant handles emissions and carbon-related concerns
Interactive displays that earn their keep
The standout hands-on area is the setup showing cold water, hot water, and a steam valve interactive demonstration. It is the kind of activity that works for adults, but it is also very kid-friendly because it turns a technical process into something you can mentally run like a system.
Carbon sequestration, explained
Another major highlight is the display about carbon sequestration. It is presented in a way that makes the topic less abstract, which is not always easy with energy and environment subjects. If you like understanding how plants manage emissions and not just how they generate power, you will appreciate this section.
Multimedia and video art
There is also a strong emphasis on screens, audio, and video art. One of the common themes is that the multimedia helps the technology click. If you are the type who likes reading labels, you can do that too, but the audio is what ties the exhibits together so you are not left wondering what you just saw.
Set your own pace
A recurring theme is that you can set your own pace. That means you can:
- Spend extra time on the interactive parts
- Skip sections that do not interest you
- Pause if the place is busy or you need a breather
If you are with family, this flexibility helps a lot, because not everyone reads at the same speed.
Views into the plant: turbine halls and outdoor equipment

This is where you need to calibrate expectations up front. You cannot enter the actual power plant area for safety and security reasons. Even exhibition staff cannot go inside. That might sound like a letdown if you have done hydro plant tours where you sometimes walk around inside the facility.
But you can still see a surprising amount of the plant machinery and systems.
What you can see from viewpoints
From the third floor and higher-level viewing areas, you get views into both high and low pressure turbine halls. From outdoor observation decks, you can also see key equipment such as:
- Pipe systems
- Separation tanks
- A steam regulator
- Cooling towers
- A scrubbing tower
In other words, you are not completely outside the technical story. You are looking at the parts of the process that keep geothermal systems running and managing heat and fluids safely.
So, think of this as a technical exhibition paired with serious observation windows, not as an inside-the-plant walking tour. If you go in expecting that style of access, you will probably feel very satisfied with what you get.
The best part of the views is how they match the earlier learning. The audio guide and displays help you recognize what you are looking at from the viewpoints. That connection is what makes the equipment viewing feel educational instead of random.

Duration, pacing, and who this fits best

Plan for about 1 hour if you stick mostly to the main path with the audio. Plan closer to 2 hours if you slow down for the interactive sections, want extra time on the carbon topic, or you are traveling with kids who will linger.
The exhibition is fairly quiet, and it can feel calmer than some big “attraction” sites. That can be a plus if you like to read and listen without a crowd pushing you along. It can also mean you are relying more on the audio to guide your experience, so do not skip it.
How to pace it
A simple way to do it:
- Start with the audio guide download first, right when you enter
- Use the interactive display as your mid-visit anchor
- Save the technical viewing decks for when you already understand what the plant is trying to do
That last part matters because it turns your sight-seeing into pattern recognition.
Who should go
This fits best if you want:
- Practical education about geothermal energy
- A self-paced stop that does not lock you into a strict schedule
- A family-friendly learning break that still feels modern and interesting
It is also a strong match if you are the type who likes how technology works, not just where it is located.
If you are expecting a big guided plant walk, you might feel disappointed. The structure here is built around exhibition viewing and audio support.
Family-friendly and easy to combine with other stops

This location is conveniently close to other activities in South Iceland, including MegaZipline. That makes it a good “one-two” stop when you want something fun and something educational in the same area.
If you are traveling with kids, the interactive steam process demonstration is the kind of moment that keeps attention. The multimedia also helps because it does not require you to read dense text to keep moving forward.
The flexibility of the self-guided format helps families avoid meltdowns. You can slow down when someone is curious and speed up when you want to get back on the road.
Price and value: is $21.69 a fair deal?

At $21.69 per person, this is priced like a focused attraction, not like a half-day tour with transportation. In return, you get a self-guided audio experience, multimedia displays, interactive elements, and access to technical viewpoints into turbine halls and outdoor equipment.
The biggest factor in value is the audio guide. If you use it, you will get more meaning from what you see, especially the process explanations and the carbon sequestration section. If you do not use it, the exhibition is still enjoyable, but the learning payoff is smaller.
It also helps that parking is free. In South Iceland, those small cost-and-time perks matter, because they reduce friction when you are driving between stops.
So, for most people who want a short, educational break tied to real industrial infrastructure, this is a solid value. If you want an inside-the-plant walkthrough, you should look for a different kind of tour style.
Should you book this geothermal exhibition entry ticket?

Book it if you want a short, self-paced stop that teaches how geothermal energy works using audio, interactive displays, and strong technical viewpoints at Hellisheiði ON Power plant. It is a great add-on for a southern Iceland road trip, especially because free parking makes it easy to plan around.
Skip it or adjust expectations if your main goal is to walk inside the plant itself. Safety rules limit access to observation areas, so you will not get the full inside tour experience.
If you can, bring an internet-enabled device for the audio download and consider packing headphones. If you do that, you will get the most out of the exhibition, from the steam process interactions to the carbon sequestration content, and you will leave with a clearer picture of how Iceland turns geothermal heat into power.
