Guided Ascent of Carrauntoohil, Ireland's highest mountain: When you make an ascent with us you will not just be tagging along – we will share a wealth of historical, geological and natural history which these mountains have in abundance. We are very passionate about this area and it shows. Guests ages 16 and up can attend. It is worth mentioning before you proceed that any ascent of Ireland's highest mountain should only be undertaken if you feel you have the required level of fitness. You will be hiking over tough strenuous mountain terrain that does not have trails for at least 6 hours. The route is over 11 kmtrs long and within that there is 1000mtrs of ascent and decent!

Highly recommend! Myself and my wife came to Kerry for our honeymoon, and climbing Carrauntoohill was definitely the highlight of our trip! I had originally considered climbing the mountain just by ourselves but my wife convinced me to book a guide, this turned out to hands down be the best decision we made. Firstly, we actually wouldn't have been able to climb this mountain by ourselves, we didn't realise just how challenging it would be. Pierce was so incredibly knowledgeable about the mountains and we felt safe with him. He is a trained mountain rescuer and we got to witness firsthand his first aid in action. Aside from this he is an interesting man with great stories of the history of the area, the flora and fauna, facts and good vibes! If you are considering hiking this mountain, firstly you need a guide 100% and secondly, the best decision you could make is to book with Pierce. Unreal day.

What an amazing day. We had the most brilliant guide Pierce. He so much knowledge of the mountain and was so interesting to hear everything he had to say. He kept us all so safe on what can be a very tricky climb and a guide is definitely needed. Cannot overstate how amazing the guide and experience was altogether. With a great coffee and BLT waiting for us at the end in Carrountoohill Hut

I’m so impressed with our guide, Piaras from Kerry Climbing, who kept us safe and entertained on our mountain climb. I highly recommend Kerry Climbing for anyone attempting the climb, especially for the first time. We couldn’t have done it without him. Tremendous experience all around!

Piaras guided my solo 14 year old daughter safely on two unforgettable hikes in March, Mt.Brandon via Paternoster Lakes & Carrauntoohil via O'Sheas Gully and down the heavenly gates. Piaras is great company, a really nice and competent guide! Thank you Piaras and Catherine!!

Another fantastic day out with Kerry Climbing, this time on the epic Cummeenapeasta Ridge. Not for the faint hearted, or for those with a fear of heights but Piaras has an incredible knack of instilling confidence in those in the group. He’s so laid back, yet so professional. An exhilarating scramble across one of Ireland’s most incredible ridges, the day was superb, the views were incredible and the sense of achievement afterwards was palpable. For anyone wishing to tackle some of the big Kerry mountains and looking for an expert guide, Kerry Climbing has to be the obvious choice. A really lovely, family run business providing epic experiences, and memories that will last a lifetime.

From the time we booked on line to being back in the car park after climbing Carrauntoohil Kerry climbing were very professional . The day we pick in October we couldn't have being luckier. Myself and the wife decided to do O Sheas Gully for the most changeling Route . Piaras was our guide for the day and was excellent , little did we know he was sizing us up from the minute we walked in from the car park on our fitness and ability to complete the climb. All throughout the climb he was given us information and history about the aera . Piaras was very helpful with my wife Joanne when we got to the tricky parts of the climb . He took lots of photos on the way and shared with us later . We took some nice breaks to take in the beauty of Kerry and were blessed with the day we got as we got to see for miles around . This experience to climb Carrauntoohil was excellent and all credit goes to Piaras and the Kerry climbing group . The climb is not for the faint heart but with a professional Guide like Piaras its a walk in the park . Myself and my wife had a great day the 7 hours just flew chatting and looking around its like you were transported into another world . I would recommend Kerry climbing to use for their knowledge of the mountain , knowing the routes and the dangers with climbing this mountain . Having a guide just made the day that much better and it took all the stress away . This was one of the things that we wanted to do for a while and feel its a great achievement. I plan on using Kerry Climbing to do anther adventure with the rest of my family . all in all great day made easier by having a great guide ,Thanks Piaras .
