A 60-year-old Czech climber died on March 27, 2026, on Kalymnos after three fixed anchor points failed one after another on a route bolted in 2002. It was an extraordinarily rare accident, and it raises urgent questions about how one of the world’s premier sport climbing destinations handles rebolting. Between volunteer burnout, murky finances, and responsibility spread so thin it almost disappears, the accident exposed the weak points in a system already under severe strain.
On March 27, 2026, a Czech climber finished climbing St. Savvas, a 5.12c (7b+) in the sector known as Jurassic Park, on the Greek island of Kalymnos. At the anchor, he went through the standard sequence to lower off and started coming down to clean his quickdraws, the clipped pieces left on the bolts while leading. As he weighted the system, both anchor bolts failed at the same time. The force then transferred to the lower bolt beneath them, which failed too. The man fell 15 meters, about 50 feet, and hit a ledge. He was conscious at first, but difficult access delayed the evacuation by several hours. He later died in the hospital from his injuries.
The Worst-Case Scenario
The news hit the climbing world hard. Kalymnos is not some obscure crag. It is one of the biggest sport climbing destinations on the planet. On this Greek island in the Dodecanese, between 12,000 and 15,000 climbers come every year to climb roughly 4,500 bolted routes, according to Aris Theodoropoulos, president of Rebolt Kalymnos and one of the major figures in Greek route development.
A few hours after the accident, Rebolt Kalymnos posted a statement on Instagram that read: “The climber did nothing wrong. The main cause appears to have been a series of failures in aging hardware.” The group is at the center of the island’s rebolting effort. Since the accident, it has announced inspections of every route equipped before 2005 and precautionary closures of sectors considered suspect.
The reaction was immediate and international. On social media, the dead climber’s wife called on people to support Rebolt Kalymnos. Donations quickly began coming in, though Theodoropoulos told us he could not confirm how much money had been raised.
“It’s the worst accident I’ve seen in 50 years of climbing”

What he could speak to was his distress. Reached by Vertige Media, he said he was “devastated” by the accident. The route where it happened was one he had personally bolted in 2002.
“It was one of my first routes on Kalymnos,” he said in a video call from the island. “It’s the worst accident I’ve seen in 50 years of climbing.” There had already been one fatal accident on the island tied to human error. But March 2026 was different. Never before had an anchor on Kalymnos failed like this.
The expansion bolts Theodoropoulos used at the time were 10 mm 304 stainless steel, a material considered standard in the early 2000s. Twenty-four years later, that stainless steel has proved poorly suited to Kalymnos’ marine environment.
“The anchor was completely corroded inside the rock. Even the best stainless steel can’t last more than 20 years here,” he now says.
After checking different sectors, the picture has become stark. Roughly 1,000 routes equipped before 2005 have never been rebolted. On an island with about 4,500 routes, that means nearly a quarter of the network could pose a danger to anyone climbing on it. Rebolt Kalymnos now recommends avoiding all of those older lines until they have been fully inspected. Fifteen sectors are also being considered for temporary closure.
The Titanium Option
Among local bolters, there now seems to be broad agreement on the technical fix: Grade 2 titanium glue-ins paired with epoxy. Titanium does not suffer from the same kind of corrosion, and the epoxy comes with a theoretical 100-year guarantee.
That choice is based on ten years of research by the UIAA, the international climbing and mountaineering federation, which updated its anchor standard in 2020 after documenting the different forms of corrosion that affect stainless steel in marine environments. The biggest danger is stress corrosion cracking, a failure mode invisible to the naked eye that can cause an apparently intact anchor to break under very low loads. In other words, a bolt that looks fine on the surface may already have lost its strength inside the rock.
Theodoropoulos knows all of this well. He says the Thai precedent has now become the reference point. “The only solution, not just for Kalymnos but for the whole Mediterranean, is titanium,” he said.
The problem is cost and supply. According to Theodoropoulos, only one manufacturer, the Greek producer Peter Lappas, currently offers anchors certified against stress corrosion cracking under UIAA standards. Reached by Vertige Media, Lappas said the alloy is much harder to work and therefore much more expensive.
“You’re looking at 6 euros per bolt on a large order,” he said. “That’s twice the price of regular stainless.” Installing glue-ins also requires careful, skilled work. “And you have to know how to do it,” Theodoropoulos added. “What we need even more than extra help is experienced, well-trained bolters.” At the current pace, he estimates it will take 10 to 15 years to secure the entire island.
Backed Against the Wall
Rebolt Kalymnos was created a year and a half ago. It now coordinates about 20 volunteers and operates almost entirely on donations. So far, the group says it has completed around 50,000 euros’ worth of work. That is real progress, but tiny compared with the scale of the job.
“We go sector by sector. It takes us 10 to 15 days for each one,” said Theodoropoulos. “We’re getting lots of offers, even from France. But it’s not easy to coordinate all of that.” So how did one of the world’s best-known climbing destinations end up relying on a small group of volunteers for both equipment and safety?
“Everything is amateur because nobody has ever put a cent back into the safety of the activity”
Claude Idoux, former route setter at Kalymnos Few people have asked that question as relentlessly as Claude Idoux. After moving to Kalymnos, the French climber poured himself into opening, bolting, rebolting, cleaning, and making the island’s climbing safer. He has since left, but not before leaving a massive mark: more than 700 routes established, between 80 and 100 routes maintained each year, and the creation of a volunteer rescue team.
In his view, the Czech climber’s death could have been avoided. “As early as 2013, when I inspected the sector where Peter fell, I warned that the area was inaccessible in the event of an accident,” he told Vertige Media. Several accounts also say the Kalymnos rescue team took too long to reach the victim on March 27.
For Idoux, all of it points to the same deeper problem. “Everything is amateur because nobody has ever put a cent back into the safety of the activity,” he said bitterly. “I often felt like I was doing everything by myself.” He says he personally spent 40,000 euros over twenty years on the island.
When he arrived on Kalymnos in 2005, this former transport-company owner had left France to fully devote himself to climbing. At the time, the island was on its way to becoming one of the major hubs of international sport climbing. After an Italian climber, Andre Di Bari, discovered the area and helped reveal its potential in the late 1990s, Kalymnos kept attracting more and more climbers. In time, it became one of the beating hearts of international climbing, with the Kalymnos Climbing Festival drawing stars of the sport as early as 2010.
“As we have seen for years, if we do nothing and wait for something from them, we are going to die”
Aris Theodoropoulos
“At first, the municipality understood the opportunity,” Idoux said. “It paid bolters, supplied hardware, and provided housing.” The goal was to build a tourism economy on an island in decline, where the small local population had mostly lived on modest tourism and sponge fishing. Today, nearly the whole local economy depends on the flow of climbers, yet little of that money seems to make its way back into cliff maintenance or rescue. In Massouri, the island’s main village, the streets are lined with packed tavernas, gear shops, bars, and rental agencies. Climbing is good business for a long list of local players. Over time, the municipality stepped back.
“To the point where it basically stopped doing anything,” Theodoropoulos said.
“And worse,” Idoux added, “when they did do something, they did it without consulting anyone. So they did it badly.” The two men, who know each other well, point to the same example. In 2018, the municipality of Kalymnos reportedly received 600,000 euros in European funding. Exactly what that money was meant to cover remains unclear. But this winter, a municipal project began to rebolt between 150 and 300 routes, depending on the source.
The problem, Theodoropoulos said, is simple: “They didn’t use titanium. They used stainless steel.” “That’s a Band-Aid fix,” Idoux said. “We now have all the information we need to know that the hardware they placed will be obsolete again in a few years.”
Idoux says he knows the company handling the job. “The guy who got that contract is from Athens. He doesn’t know what he’s doing. He has no history here. Odds are he’ll rebolt routes that don’t even need it.”
Theodoropoulos reached a similar conclusion, in less colorful terms: “Officially, they are the ones responsible. They are in charge of climbing on the island. But as we have seen for years, if we do nothing and wait for something from them, we are going to die [sic].” Contacted by Vertige Media, the municipality had still not responded to our questions.
Money and Blood
Now that he has broken his silence, Idoux says the first step is obvious: stop opening new routes and focus on making the existing ones safe.
“Honestly, nobody even knows anymore how many routes there are on Kalymnos,” he said. “Some people say 4,500, some say more than 5,000. There’s no point in having more lines if the ones already there aren’t being maintained.”
Unless, of course, some people benefit from that situation. That includes Theodoropoulos himself, who is both president of Rebolt Kalymnos, whose mission is rebolting, and owner of the guidebook, whose commercial value depends in part on new routes being added with each edition. Asked about that by Vertige Media, the Greek climber said some of the guidebook revenue does flow back into his association, though he did not provide an exact amount.
“The economic players need to get off their asses. They all profit from climbing, and at some point they have to put some money back in”
Claude Idoux According to Idoux, very few people on Kalymnos handle cliff maintenance with no personal stake in it. He does not directly blame Theodoropoulos, but he says he would not want to be in his shoes. “I’ve always preferred my position to Aris’ because he makes money off volunteer work,” he said flatly.
After a fatal accident, everyone has a reason to point somewhere else. On Kalymnos, where the interests are tightly entangled, that becomes especially easy. But for Idoux, the responsibility is collective. Long before the Czech climber died, he had already been pushing for a professional rescue team and for three full-time people dedicated to route maintenance year-round. That costs money.
“The economic players need to get off their asses,” he said. “They all profit from climbing, and at some point they have to put some money back in.” He has no shortage of ideas. He first tried, unsuccessfully, to set up a membership-card system to fund his rescue team. Today he believes an arrival fee could work.
“Every climber comes over by boat from Kos. You catch them when they arrive and make them pay a fee. I’ve got plenty of friends who’d be willing to pay. When a Swiss friend tells me he pays 30 bucks for four hours in a climbing gym, well, this would be the same price to climb in one of the most beautiful places in the world, safely.”
Idoux has ideas. But Idoux is gone. The Frenchman abruptly left the island, selling off all of his assets there. On the phone, he described what he called a complete breakdown after another episode in which he again found himself at the center of an emergency.
“I had to help some young people who’d wrecked their car. Nobody came to help them. Meanwhile the mayor of Kalymnos was having dinner with the Japanese ambassador. I walked into the restaurant covered in blood and told him this had to stop. That’s when I realized there was no will on their side anymore.” A few days later, he left the island, leaving behind the same knot of responsibilities and failures, still very hard to untangle.
The UIAA is now trying to do exactly that. From May 1 to May 6, the organization will hold a meeting on Kalymnos. It had been planned before the accident, but it now carries a very different weight. The municipality, Rebolt Kalymnos, and the local rescue team are all expected to sit down together. Two days will be devoted to rebolting training based on international standards, and the bolts from St. Savvas will be analyzed in a lab.
For Theodoropoulos, the meeting represents a measure of hope. “I hope something good comes out of it,” he said simply. In the meantime, doubt is already settling in on the island. Local professionals say they are seeing concern rise among clients, with some now asking for guarantees or limiting their climbing to sectors that have already been rebolted with titanium.
The March 27, 2026, accident brutally exposed the reality on Kalymnos: a municipality that is officially responsible but barely involved, an economic model whose profits do not seem to flow back into safety, and volunteers overwhelmed by the size of the task. Can the UIAA meeting finally force a clearer distribution of responsibility? If not, how long will it be before another anchor fails?
The questions are not new. But after a climber has died, no one can ignore them anymore.
