One of our top experiences in Thailand. Mon was an excellent guide - friendly, knowledgeable, and also had a very relaxed demeanor that put my wife and I at... read more ease. We were picked up at our hostel in Krabi and did a half day at Railay. Amazing views and challenging runs.

  We had a great day rock climbing! Even if it looked scary at first, our guide Mon made us always feel safe. He was very professional and patient, but also... read more a very easy-going, friendly person that we enjoyed spending the day with. It was an amazing feeling standing on top of the rock and watching the amazing scenery. The one-day course included everything (hotel pick-up, equipment, guide, rock climbing, visiting a cave and rapelling from it and even lunch!), so we got good value for the price. We would definitely recommend it!

  We chose Karst climbing by reading the reviews and we weren't disappointed. The best climbing experience of my life. To be recommended absolutely. Mon simply the best

  My partner and I did the full day climbing and it was amazing. We are both intermediate climbers. Mon was a very skilled climber and friendly. He did a great... read more job at choosing routes for us that were interesting and varied. Would definitely recommend!

  Fifteen years ago, my now husband and I came to Thailand. We stayed on Railay, and learned to climb. Our trip ignited a passion, and we continued to return to... read more Railay every year to climb on the limestone rocks progressing from top roping to lead climbing. Leap forward to 2020, and we wanted to bring our children (aged 5 and 7) to Railay to enjoy some rock climbing too. We haven’t done any lead climbing since 2011, so wanted to have a guide for our trip to Railay.
I looked at various guides, and they generally all have the same marketing, so our choice came down to reviews and availability.
Karst Climbing is a fairly new outfit, with good reviews, and they could do our dates. Communicating with Karst climbing was easy, with quick, comprehensive responses to our emails. We booked an initial half day, paid online and were met by Mon at our hotel on the morning of our first session.
He drove us in his truck to his shop, loaded up with gear, and we headed off to the pier to travel to Railay.
He set up a rope on 123 wall and got a feel for our abilities, and worked well with the kids, our daughter was very keen to climb, but found the transition from indoor climbing wall to rock very challenging, and Mon showed great patience and kindness towards her. Our son, who is older and has more experience, got a bit shaky on one climb, so Mon chose another route which was better suited to him, and helped build his confidence back up.
He also set up ropes for me and my husband and was happy for us to belay each other or the kids using his gear whilst he belayed another one of us, enabling us to maximise our time with him.
Our first day was so good, we booked the following morning with Mon, and went up to Diamond Cave for another great few hours of guided climbing. Our daughter didn’t climb on the second day, but was so taken with Mon that she has declared she will climb with him next time we come to Thailand, and was chatting to him all the way back to the long tail.
We have been very lucky to have only had good climbing guides in Railay, but we have witnessed plenty of disinterested guides who don’t support their customers to get the most from their climbing experiences. Mon was a fabulous guide, he knows the climbs well, he was brilliant for our family with our mixed abilities and ages, and I would recommend him to anyone looking to climb in Railay.

  It was a great experience to try out rock climbing for the first time. Everybody was really friendly and Mon created a very easy going atmosphere so everything went down... read more really well. Thank you!More

  We had a brilliant half day of climbing with Karst climbing. Mon was our guide and he made sure everyone in our group of six was safe and happy. We... read more were able to do a lot of climbing (6 ascents) in that short period of time, which was awesome. There were also difficulties for all skill levels, we have a bouldering background so we were very happy that we could choose climbs that were a little bit harder. Would definitely book here again!

  I was very lucky meeting Mon accidentally on the Phra Nang Beach climbing with two other people. So glad, that I talked to him and booked the full day Climbing... read more and Caving tour with his company! Mon is a very relaxed guy, I always felt...More

  Just returned from a trip to Thailand and the highlight was definitely a full day of climbing with Mon. The location was amazing and he picked out the perfect routes.... read more We were a group of varying grades in rock climbing and there was something for everyone.

One of our party wasn't well on the day and Mon went out of his way to arrange a loft back to the hotel.

Hands down the best experience and a great guide for all abilities.

  We had a great climbing-day with Mon in Railay. I liked that there was enough time for climbing many routes.
