HIGHLANDER, now considered the leading long-distance hiking event series in the world, was founded in Croatia in 2017 by Igor Mlinarevic, a veteran event organizer with stops at Ironman 70.3, the Tour of Croatia, and the Pannonian Challenge, among others. The self-proclaimed "hiking evangelist" wanted to combine his two passions — hiking, and designing experiences that people love — and HIGHLANDER, "the Adventure of a Lifetime," was born. 

The first-ever HIGHLANDER event was held on Velebit, the largest mountain range in Croatia, along the Adriatic coast. Since then, the brand has expanded rapidly across the globe, with iterations in Egypt, Morocco, Slovenia, Austria, France, North Macedonia, the United Arab Emirates, Bosnia and Herzegovina, Greece, Portugal, Montenegro, and Serbia. When Spartan CEO Joe De Sena got wind of HIGHLANDER CEO Jurica Barac's vision for the unique hiking experience — to not just change lives, but to save the planet with a leave-no-trace focus — the two formed a strategic partnership in 2021. Just a few months later, HIGHLANDER landed on American soil for the first time ever, launching its inaugural U.S. even in Big Bear Lake, California. 

"Big Bear was truly the 'Adventure of a Lifetime' for me," hiker Jessica Long said. "This event changed my life and came at a time in my life when I really needed it. I was able to be surrounded by so many kind strangers and come out the other side with so many beautiful friends, and to dig deep in myself and feel that I am worthy."

With multiple formats — from two-day, 15-mile excursions to three-day, 30-mile trips, and all the way up to four-day, 60-mile expeditions — these events offer a life-changing experience where you can connect with Mother Nature, explore the most unseen corners of the globe, and build unbreakable bonds with fellow hikers over shared interests, no matter your athletic ability.

Here's everything you need to know about the 2024 HIGHLANDER long-distance hiking events. 

The 2024 HIGHLANDER Long-Distance Hiking Event Schedule for the United States

HIGHLANDER Big Bear Lake, California (June 19-23, 2024)

In 2023, more than 200 backpackers spent up to five days trekking close to 103 miles starting at Snow Valley Mountain and continuing to the top of Keller Peak, where they were left speechless by views of Arrowhead, Gregory, and Silverwood Lake. Over the few days, hikers journeyed through the greenest part of the expedition, Little Green Valley, and all of the way to the desert-like Cactus Flat. They could even choose to summit Sugarloaf Mountain, the highest peak in the San Bernardino Mountains outside of the San Gorgonio Wilderness, with a peak elevation of 9,952 feet.

Along the way, backpackers were enriched with lectures by the likes of Dean Karnazes, a well-known ultrarunner and one of TIME's most influential people in the world; a retired U.S. Navy SEAL officer; a best-selling author; and others, and they learned how to protect our nature and the environment, relaxed with live music and private concerts, and practiced yoga atop a mountain.

They even managed to pick up 495 pounds of litter while out on the trail.
