Kayak with Coo Adventure has been one of the worst experiences in my whole life. I and my girlfriend arrived in Coo very enthusiastic to do Kayak for our first time, and we booked 2 tickets for the afternoon (we were told approximately from 1pm onwards, when the level of the water would be sufficient to do kayaking). At 12.30 sharp, we get to the starting point, where all we hear is: "you have paid already, you can take a kayak, we will push you into the water. Enjoy!"; no questions, no explanations, no indications, NOTHING. Just like that. Being my first time, I didn't worry as I thought "it's maybe easier than what I think"... but there the nightmare starts. I and many other people get continuously stuck and trapped among the rocks due to the absolutely insufficient level of water, a superhuman effort to move on just a few meters before getting stuck again. I am not expert and perhaps not even good at all, I know… but that was too much. Additionally, the effort was even bigger as all the time I had to take care of my belongings: phone, sunglasses, wallet… because nobody tells you that there’s a chance to get flooded or even to fall down into the water, so I brought my valuables with me. The total route is about 8 km and there’s no signal along the river on how much is left… at some point, I was exhausted, and even discouraged after I understood that I was only at half the way… and after falling down into the water, loosing my glasses, getting totally wet, even my phone (luckily still working) and my wallet, I decided to give up and call them for rescuing me. At this point, their help on the phone was first: “if you are not feeling well, call a doctor” (but I was in the middle of a river!!!) and then: “just get out when you can, when you spot a house or such, call us back and we will send somebody to pick you up”. And I did. I got out in the surrounding field (God only knows how! Let’s just skip this part…), managed to get to the main road and called them back, but nobody took my call. Several calls, zero answers. At some point, one of them just passing by (by chance) saw me and picked me up, so my nightmare came finally to the end. I am aware that the level of the water only depends on nature, but I would expect a service provider like this to be more honest on the real conditions of the river and to comply at least with the basic rules of safety and not just throw people into the water and God bless them… at least some basic indications, some assistance to those people who have never experienced this sport and would like to enjoy an alternative afternoon… not to live an unforgettable nightmare. Totally not recommended.
