Worth trying - Max was a great and funny guide, i recommend!! Experience was great, max told us a lot of interesting facts about history of these tunnels,some ukrainian law and showed us some tricks inside the tunnels, Ačiū!!

Круто - It's so cool when we made silence with no lights for few minutes. Guide knows his job as well History of this underground place like his five finger

One of my favorite tours I’ve done - I went on a tunnel/bunker tour with my brother, his gf, and a friend lead by Max and it was seriously one of my favorite tours I’ve ever done (and I’ve traveled a decent amount). It didn’t feel like any sort of typical tourist attraction I’ve done before, and that’s exactly why I picked it. All four of us thought it was great, one of the highlights of the trip. It isn’t for everyone though, my group was all late 20s early 30s, in good shape and ready to get dirty and explore. I don’t recommend this for people who are overweight, claustrophobic, or worried about getting dirty (soil and mud dirty, not sewage!). My group loves hiking and climbing, so it was a perfect fit for us!

Interesting activity but could be improved - I personally did not have a good experience, but I understand that most people would love this and rate it high so I did not want to rate this too low and bring the ratings down. One thing to say right away is that our guide Vlada was awesome, spoke perfect English and was fun. Now why I did not like it: - It starts at 11AM and is 3 hours long. (Maybe they have different timeframes, not sure because my friend is the one who booked), I think it is not a good time at all because the adventure is physical and you get very hungry in that time frame. - There is a long, very small tunnel near the beginning of the tour. This is what killed me. On an empty stomach this tunnel really made me feel exhausted right away (and I’m a thin guy who does sports often) yet my heart was racing and I felt weak because of that tunnel. For me the rest of the tour (which thankfully wasn’t that physical) was spent trying to recover from my fast heart rate and stressing out wondering how many more of these tunnels I would have to go through. Because of that, the whole experience was ruined for me and I did not feel good the entire day. Two easy ways to fix that: 1) Change the time to either early morning (after breakfast) or afternoon... 2) The guide should quickly go over the layout of the tunnel before the group heads inside. At least people who have concerns or are stressed know what to expect.
