    Lilli is a superb tour guide.

    Lilly was our tour guide, she was exceptional at telling facts about all of our stops. The entire trip was enjoyable, but unfortunately, at the last stop my mom lost her iPhone. We will definitely book excursions again.

    Response from the operator: Hi Michelle, glad the day was enjoyable and sorry about the iPhone. If it hasn't turned up yet, please email info@adventures.is with the tour date, booking reference number and the last stop location, we'll do what we can. Arctic Adventures Team

    Great golden circle experience

    Our tour guide (Bruno) for the golden circle part was awesome!! He even prepared a sweet treat for everyone at the end of the tour. We really had a great time with Bruno.

    Response from the operator: Hi Vicky, thank you for the kind review. Glad the Golden Circle part of the day was such a good one. Until the next Iceland trip! Arctic Adventures Team

    Non-responsive Company

    When I booked the tour, the booking said that the tour started at 8:00. I had wanted to be picked at bus stop #6. I emailed the tour operator, Arctic Adventures, three times, twice via their website and once through Tripadvisor asking what time I would be picked up at bus stop #6 and when should I get there. Receiving no response, I canceled my booking and booked with someone else.

    Response from the operator: Dear Peter, thank you for your feedback. We are sorry to hear about your experience. After reviewing our records, we can confirm that we received one message via Viator on April 14 and replied to the following morning within less than 24 hours. We were unable to locate any additional inquiries. However, we have since identified and resolved an issue that may have affected "pick up" message submissions through our website form at that time. During this period, our average email response time has been under 24 hours. We understand how important timely communication is and regret any inconvenience this may have caused. For urgent questions, we also offer phone and live chat support. Thank you again for bringing this to our attention. Arctic Adventures Team

    Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour: questions travelers ask

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

    How much does Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour cost?

    +

    Prices start at €136 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 Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour take?

    +

    Plan for about 10 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 Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour worth it?

    +

    It holds an Outty Ranking of 61 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.3/5 across 31 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 Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour?

    +

    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 Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 10-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour?

    +

    Around 11 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 10-hour experience runs outdoors or after sunset.

    Where does Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour 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, Silfra Snorkeling Between Continents Photos Included- Self Drive, Small-Group Golden Circle, Blue Lagoon with Ticket & Kerid Crater. 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.

    What is included in Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour?

    +

    Included: Small group experience; Professional guide; Reykjavik pickup and drop-off; Use of caving equipment; and Free wi-fi on board. Not included: Food and drinks; Gratuities; and Lunch. Always check the voucher for the final list before you travel.

    Does Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour include hotel pickup?

    +

    Yes, pickup is offered for every traveler from 23 listed pickup locations in and around Reykjavik.

    What languages is Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour offered in?

    +

    Is Reykjavik: The Lava Tunnel and Golden Circle Small-Group Tour wheelchair or stroller accessible?

    +

    The operator notes: Infants are required to sit on an adult’s lap. If accessibility is critical, contact the operator after booking to confirm arrangements for your date.
