    Absolutely worth every penny

    Incredibly knowledgeable guide who was able to look at a massive lava field and immediately pick out unique lava rocks literally millimeters wide to show the group. She was also very knowledgeable about the history, industry, and economy of Iceland and many of the features we drove past. The itinerary was great with a mix of hiking, geology lessons, scenic vistas, and lunch ON some of the newest rock on earth. She made sure to warn us of potential hazards, and even had paracetamol ready when I slipped and twisted my ankle (no serious injury). The trip itself started at the base of the lava flow from the 2021 eruption sequence. It was about 2 km to the summit of a nearby mountain overlooking the lava field and active volcanic crater, with many spots still venting steam as of August 2026. There were multiple stops for rest, geology, and pictures. I have asthma but never needed my inhaler, so it was not too strenuous. The highest point was about 200m up from the parking lot. After the hike, we drove along the coast before going north towards Reykjavik. We drove past a geothermal area and briefly stopped at an incredible overlook above a lake.

    This tour was awesome!...

    This tour was awesome! France was such a great guide - she provided so many details about what we were looking at that it made the whole experience so rich and interesting. I had no idea that lava had so many stories to tell!

    Made my wife cry; do not book with them!

    They canceled our tour at 10pm the night before with no explanation, leaving us with no plan for the next day and no time to find anything else. My wife loves geology, and was so excited to have a volcano tour with a real geologist; she burst into tears when it got canceled. When I emailed them to check in, all three email addresses I tried bounced back. They have not refunded us and we are now having to dispute the charge with our credit card. DO NOT TRUST THIS COMPANY.

    Invigorating education

    Fantastic and educational hike up to some beautiful lava fields and expansive views of the whole region. We also stopped at a lovely lake and the mostly abandoned town of Grindavik. A couple of turns on the hike are steep, and the way down a bit slippery but it's doable. What made the tour special was the wonderful guide who taught us the many geologic forces at play, the results of continuing lava flows and made us aware of the dangers that may exist of one strayed too far on their own. Our geologist was incredibly accommodating to all guests and was a pleasant leader for the small group. Also gave an excellent recommendation for Fish Company which I thoroughly enjoyed after a great tour.

    Small Group Volcano Hike with a Professional Geologist: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Reykjavik.

    How much does Small Group Volcano Hike with a Professional Geologist cost?

    +

    Prices start at $182 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Reykjavik usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Small Group Volcano Hike with a Professional Geologist take?

    +

    Plan for about 6 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Reykjavik is not rushed.

    Is Small Group Volcano Hike with a Professional Geologist worth it?

    +

    It holds an Outty Ranking of 75 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.7/5 across 154 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Reykjavik, and how flexible the cancellation terms are.

    Can I cancel or reschedule Small Group Volcano Hike with a Professional Geologist?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Small Group Volcano Hike with a Professional Geologist suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 6-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Small Group Volcano Hike with a Professional Geologist?

    +

    Around 54 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Reykjavik can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Reykjavik and add a light layer if any part of the 6-hour experience runs outdoors or after sunset.

    Where does Small Group Volcano Hike with a Professional Geologist start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Reykjavik within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Reykjavik?

    +

    On Outty we rank every Reykjavik experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Reykjavik Food Walk - Local Foodie Adventure in Iceland, Small-Group Golden Circle, Blue Lagoon with Ticket & Kerid Crater, Reykjavík Small group Walking Tour - by CityWalk. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Reykjavik?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Reykjavik?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
