Walk Falljökull Glacier, enter a natural blue ice cave, and learn about Vatnajökull with expert guides near Skaftafell.
“This was a great activity, not sure where all the bad reviews come from. If you keep your expectations in line with reality and not social media, you won’t be disappointed! It was amazing to be on a glacier and see the ice cave & crevasses. Do not book if you’re not in relatively good shape as it involves a lot of walking and climbing on snow and ice. Equipment is provided and it feels totally safe. Great Iceland experience!”

“Amazing tour, would go again - the guides were very patient and knowledgeable about glaciers and gave a good history on the nature of glaciers. Had plenty of time to wander and explore the ice cave too! (We visited the Sapphire ice cave)”
Explore Vatnajökull’s blue ice caves by 4x4 and glacier walk, with expert guides, small groups, gear included, and flexible booking.
“I'm not one for booked activities / tours but this was unmissable for me and I loved every minute of it. Hanka, our guide, was informative and engaging and had good judgement. She balanced the group's needs well. We were lucky with the weather, which made this all the more enjoyable. I had thought I'd booked the ice-caves and glacier hike, however the 'hike' element didn't really happen. If I had money to spare then I'd love to do a full day tour and really explore the glacier. I had expected a bit more exploring but in all honesty I loved just looking at the incredible ice, taking a gazillion…”

Review the Vatnajökull ice cave tour from Jökulsárlón, with practical details on price, transport, crowds, safety, clothing, and value.
“The cave is breathtaking, there’s no doubt about that. (Well, based on what the guy said, they change and it also depends on which cave you visit). Our guide was also nice and knowledgeable! BUT, it’s really overcrowded with people. There were at least 10 groups inside (approx 15 people per group) and when we left there were 3 groups waiting to go inside. Cave visit itself is pretty short (45min.) based on description saying 3-3.5h trip you’re done in 2 hours. I’m not saying it’s not worth it as some people were amazed and loved it. But for us, who wanted a bit of space and not a huge…”

“We had an amazing time and experience with Boggi and his well equipped and secured off-road truck. The natural ice cave was spectacular. We visited it at lunch time which was on purpose as there were no other groups. Magnificent colours and walking and photo shooting under the ice of the glacier. It’s a must do thing with this small customer focused company.”

Review of Reykjavik’s Snæfellsnes day tour, with Kirkjufell, Vatnshellir Cave, waterfalls, churches, lava fields, and practical tips.
“this was a great tour to see the peninsula. Loved the small group as it allowed us to enjoy ample time at each stop before quickly moving to the next stop. Smari was our guide and was very knowledgeable as he was raised on the peninusula. He was able to quickly adjust the schedule to take full advantage of the weather. We visited seals, beaches, waterfalls, the black church, rock formations and caverns. We were fortunate enough to have a clear day and a great view of the glacier.”
Review of the Vatnajökull blue ice cave tour from Jökulsárlón, with pricing, transport, gear, hiking details, value, and practical tips.
“Tour starts in the lagoon, you drive with huge terrain vehicle to the glacier around 30min. Then you hike to the cave around 10min. I like that tour is in a small group, around 10 people, compared with other providers with 20+ people. Cave is beautiful! Our guide was very sweet and funny, also sharing really interesting facts about glacier history, cave formation process etc. He was also very helpful, doing photos of everyone and made us feel very welcome. Genuinely recommended.”
