My husband and I took our 11 year old son on the underground adventure with Sol and it far exceeded our expectations. Our son loves adventure and gets bored easily but over the 4 hours we spent with Sol, he kept things engaging and the activities involved were suitable for an 11 year old, but added a sense of controlled ‘danger’ which held my sons enthusiasm and interest (he’s an adrenaline seeker). For me personally, I have a couple of injuries which limited my ability to participate in some of the activities, which wasn’t a problem. Sol had alternative ways to move forward which did not require scrambling, zip lining or abseiling. My husband had a great time and also felt the activities were the right level of difficulty to be a challenge but not too hard. All in all, a very enjoyable experience.

Great adventure - great day out!

Great afternoon with our guide Sol who was very knowledgeable about the mine and it's history. Our trek though the mines was done at our own pace and we had choices whether or not to do certain challenges. Great experience would highly recommend !!
