At the first meeting, Car, the garden, Dowoon, Lee Chae-min and Tarzzan discover why they were gathered: to climb the imposing Seoraksan.

The members tackle Seoraksan's brutal 10-hour course. Pork belly and ramyeon at the shelter taste like heaven — but the real hell begins on the descent.

They head up Taebaeksan on a tempting offer that could make future hikes easier — but the steep trail leaves Car, the garden with pain in his leg.

The four race the clock to reach the summit before sunrise. During a Korean beef feast after the hike, they learn that the next peak awaits in Jeju.

After soaking up Jeju's charms, the group splits up for their next climb — only to find one team's path smooth and the other's far tougher than expected.

After brutal climbs and burning lungs, they reunite at the legendary Baengnokdam. For a brief moment, the stunning view makes them forget the pain.

The club heads to Ulsan, Tarzzan's hometown. Later, a surprise during the break turns out to be exactly what they'd wished for: a game with Nah Yung-suk.

The Yeongnam Alps hike gets off to a rocky start, but a sea of golden reeds keeps them going — and even makes Car, the garden pull out his phone.

After stopping by Tarzzan's place, they dive into a final showdown with Producer Nah. Play it right and they might just flip the whole show on its head!

The four take on their final mission — hiking the nation's "sacred" mountain — and wonder if they finally get why on earth people go to the mountains.
