Before I tell you about our recent experience rock climbing, be assured that almost anyone in reasonable shape can do it. You do not need any previous experience, you do not need to be super buff or thin or young. Trust me. I had never rock climbed before last year (hadn’t even considered it) but some friends had done it and raved and something about living in Thailand makes me want to try new things so I figured what the heck, right?

Plenty of climbers but plenty of secluded routes, too
Railey Beach in Krabi is surrounded by amazing karst rock formations and, over the years, has become a rock climbing destination. There are hundreds of routes already bolted (plenty for beginners but also plenty for experienced climbers), and a couple of rock climbing shops where you can buy or rent gear. Better yet, if you are beginner, you can hire a guide who’ll bring you out and teach you everything you need to know.
The first time I tried rock climbing, I went to a shop called Hot Rock in Railey with a group of friends. We happened to get an instructor named Khun Pboo (which, fittingly, means crab) and he set us up with gear, gave us a safety briefing and then took us out to some of the routes on Railey East. I will not lie, it was a little scary but there was plenty of instruction and Pboo was great. I basically failed at my second climb but he made me get back on the rock and finish with an easier climb, telling me – if you don’t finish one you’ll never come back. Thanks for caring. ☺
So this time around I was happy that we had Khun Pboo again. He took us to some cliffs near Phra Nang beach and the routes were definitely harder than the ones we did last year but we all completed at least one climb. He was great with my sister C, who had never climbed before, and the view from the cliffs was amazing!

nice job sis!
But the best part of the day was when he led us through some of the caves, into one of the large cliffs. I’m not going to lie – there were bats, rickety bamboo ladders, rope pulls and, at times, absolutely no natural light. We loved it; I can see why some would find it miserable or scary.
We emerged through a cave some 45 feet from the ground. When I saw what we had to do to get down, I thought – oh no. But the only other option was climbing back down through the bat caves with my head hung in shame so it had to happen.

from that angle, it looked a lot higher than it actually was, not that that made me feel any better since i couldn't see the ground
And it did.
Experienced rock climbers don’t need to be reading this because you probably already know a lot more than I do, but if you’re a beginner and interested in trying, here’s some helpful information.
Most of the rock climbing schools in Krabi offer half day guided climbs, and will give you everything you need to climb. Expect to pay anywhere from 800B to 1,200B.
Even if you’re in great shape, you’ll definitely feel it the next day. If you’re a beginner and interested in climbing more than one day, leave a day in between to recover.

see the rope attached to J and Khun Pboo?
As a beginner, you will always be belayed by your instructor or partner. That means there is a rope looped through an anchor at the top of the route. You are attached to one end of the rope and the belayer has the other end and controls the amount of slack. If you fall, the belayer will lock off the rope and act as a counterbalance so you do not fall far (at least I think that’s how it works). It’s meant to be as safe as possible, but rock climbing is an inherently dangerous activity. People hurt themselves. All of us got banged up and bruised, worse could happen.
I asked Khun Pboo what types of folks generally want to try climbing in Krabi. He says he’s seen everything, including people in their late sixties (who, he says, had a lot of fun).
