About this experience
Like Ralph Waldo Emerson once said. Do not go where the path may lead. Go instead where there is no path and leave a trail. Agenda is as simple as 2 + 2 first we’ll warm up hiking to our farthest destination, before descending into each cave we start with stretching, then exploration time and be ready for some squats, push-ups and more stretching ! More effort you put into these exercises more you’ll see and oh boy take our word for it, there is plenty to see ! Depending on your fit level we’ll see anywhere between 2 to 4 caves. So you’ll get some cardio/ work out day for sure. We do caving often and we know there is nothing better than warm bath after half a day spent underground in humid and cool environment but than again bath sounds sooo boring. Unless you are in Iceland where you can just simply submerge yourself in a natural hot geothermal stream... Found in a beautiful valley up in the mountains, enjoining tasty Icelandic style hot dog prepared with a help of hot springs!

Best Iceland Excursion!
This is a very unique experience as it is a private tour, and our guide Damian was incredible! He takes you to various caves and shares his knowledge of the rock formations and geological sites as you crawl through and climb over rocks and passages. Afterwards, we drove to a remote are where we hiked to a scenic geothermal river to bathe, and then had a lunch of Icelandic hot dogs which he cooked for us in the hot springs! This was a very physical experience, but Damian will go at a pace that is comfortable for each participant. Be prepared for a fun filled day as well as a workout!

Unique Caving & Hot Springs Tour - not the norm
Only in Iceland for 4 nights, so spent a long time looking for tours which combined things we specifically wanted to do. Stumbled upon G spot Iceland, and how glad am I we did. The tour we picked was caving & the hot springs in the mountains (Hot and Cold G spots challenge). We never look for 'personal/non-touristy' tours, as they are hard to find and mostly very expensive. Well, this is what we got, and for a great price! Only the two of us on this particular tour (although they cater for more), with two guides. Took a punt with the caving, and instead of doing the caves with queues of tourists queuing to get in, we went to some caves where no tourists ever go. When we arrived (in very snowy and windy conditions), every cave entrance was buried in several meters of snow. This, however, would not prevent our guides from digging through several meters of snow and ice to gain entrance to one of the caves! Cave was amazing with several chambers linked via small crawl-throughs (no-one else was in the whole region, and definitely not in the cave) , and more than worth the effort to get in. Next was the hike to the hot springs in the mountains. It's a long trek, but well worth arriving at this natural phenomenon, and taking a dip in the hot spring surrounded by snow was a little surreal. Cooking hot dogs in a thermal pool finished the day, and returned back to the hotel shattered after a long 10 hour day! The guides aren't your traditional tour guides, they are cavers who have turned their passion into a tour - these guys are incredibly knowledgeable about all things 'caving & geothermal', and always considered safety a priority during the caving. If you want to do the generic tourist route, where you will be surrounded by other tourists trying to get a good shot, then these guys probably aren't for you - stick with the 'BudgetIceland' type tour company. If, however, you want to go off the beaten track, and really get a sense of what Iceland is really about, then 'G spot Iceland' are the tour guides for you (I say 'tour guides', it really didn't feel like that, it felt more like hanging out with a couple of buddies and letting them show you what they love - Iceland).

Why this scores 63
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Hot and cold G spots challenge: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Reykjavik.
How much does Hot and cold G spots challenge cost?
+
Prices start at $210 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 Hot and cold G spots challenge 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 Hot and cold G spots challenge worth it?
+
It holds an Outty Ranking of 63 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 3 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 Hot and cold G spots challenge?
+
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 Hot and cold G spots challenge 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 Hot and cold G spots challenge?
+
Around 1 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 Hot and cold G spots challenge 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.
