Alone Season 12: Africa

Ten survivalists begin the season in South Africa's arid Great Karoo, the show's first-ever desert setting, where finding water quickly becomes as urgent as finding food. Kelsey Loper lands the season's first big kill with a warthog she smokes for later use, while Katie Rydge and Will Lamb work on early fishing and water-purification routines. Jit Patel's stomach illness worsens rapidly, and he becomes the season's first tap-out only four days in.

Out this episode: Jit Patel (day 4, medical)

• Kelsey Loper kills and butchers a roughly 55-pound warthog, the season's first big-game kill
• Katie Rydge catches an orange river mudfish on Day 1
• Will Lamb sets up a boiling-based water purification routine to guard against pathogens
• Aggressive baboon troops become an early recurring hazard around camps

The other half of the cast, including Nathan Olsen, Douglas Meyer, Dug North, Colton Gilman, and Baha Mahmutov, get their introduction as they establish desert camps. Nathan finds early success fishing with grasshoppers as bait, while Baha struggles for hours trying to start a fire with a bow drill. The strain of isolation catches up with Colton Gilman, who taps out four days in after recognizing he is in a mental health crisis.

Out this episode: Colton Gilman (day 4)

• Colton Gilman lands a roughly 10-pound African sharptooth catfish and preserves it as soup and dried meat
• Douglas Meyer has a close nighttime encounter with a rhinoceros near his camp
• Baha Mahmutov struggles for hours with bow-drill fire-starting
• Dug North catches and cooks crabs alongside foraged plants

Extreme heat and water scarcity define this episode as two contestants are forced out within hours of each other on Day 5. Pablo Arguelles can no longer keep himself hydrated in the punishing desert conditions and taps out, while Will Lamb is medically evacuated after vomiting blood and being diagnosed with acute colitis. Kelsey Loper and Douglas Meyer make steadier progress, building water caches and carved containers to manage the same conditions that beat their castmates.

Out this episode: Pablo Arguelles (day 5, medical), Will Lamb (day 5, medical)

• Two tap-outs on the same day: Pablo Arguelles and medically evacuated Will Lamb both exit on Day 5
• Kelsey Loper builds a water-cache system and a bluebush-and-tarp shelter
• Douglas Meyer carves a water-storage container out of agave
• Contestants spot waterbuck skeletons, a grim reminder of the region's scarce water

With six contestants remaining, colder nights push everyone into shelter-reinforcement mode even as daytime heat and thirst continue. Nathan Olsen upgrades his fishing line after losing gear to an oversized catfish and lands a 35-inch catch using a scorpion for bait, while Dug North discovers scorpions can double as food, roasting one after removing its stinger. Katie Rydge and Baha Mahmutov both make headway on hunting and shelter design, and for the first time all season, nobody taps out.

• Nathan Olsen catches a 35-inch catfish using a scorpion as bait after upgrading to 120-pound fishing line
• Dug North eats a roasted scorpion after removing its stinger
• Baha Mahmutov lands a 30-inch catfish worth about 1,700 calories using beetle and centipede bait
• Katie Rydge builds a half-dome shelter from saplings and acacia bark string

A rare, heavy desert downpour of about three inches of rain floods camps built along dry riverbeds and forces Kelsey Loper to rebuild on higher ground. Douglas Meyer decides the storm, combined with worry over his father's declining health, is reason enough to head home, tapping out on Day 14. Dug North also struggles badly, collapsing near his camp at the end of the episode after apparently not drinking enough water despite feeling well-fed.

Out this episode: Douglas Meyer (day 14)

• An unusual desert storm dumps around three inches of rain, far more than the area's typical monthly average, and floods Kelsey Loper's riverside camp
• Nathan Olsen catches an elephant shrew to use as catfish bait, then lands a roughly 3,200-calorie catfish
• Katie Rydge weaves a reinforced shelter inspired by Aboriginal weaving techniques as lightning strikes overhead
• Dug North faints near his camp at the episode's end after apparent dehydration

The episode opens moments after Dug North's collapse, and he ultimately decides his fainting spell is too serious a safety risk to continue, tapping out on Day 14 to keep a promise to his wife. Kelsey Loper keeps fishing despite a stove mishap that nearly injures her, Nathan Olsen begins a labor-intensive dry-stack stone shelter, and Baha Mahmutov misses a shot at a greater kudu but finds food in buffalo thorn leaves.

Out this episode: Dug North (day 14, medical)

• Dug North taps out after his fainting spell, calling it 'a hell of an adventure'
• Kelsey Loper's cooking stove explodes while she prepares a 15-inch catfish, though she is unharmed
• Nathan Olsen begins building a permanent dry-stack stone shelter
• Baha Mahmutov misses a shot at a greater kudu and turns to foraging buffalo thorn leaves

Down to four contestants and all of them hungry, the psychological weight of the competition becomes the main story. Baha Mahmutov, who has been losing sleep every night trying to keep a fire going without a ferro rod, decides money isn't worth the toll on his mental state and taps out on Day 19. Kelsey Loper gets an emotional lift from an unexpected encounter with a giant tortoise, while Nathan Olsen lands a nearly four-foot catfish at night and quietly processes the grief of his son's death.

Out this episode: Baha Mahmutov (day 19)

• Baha Mahmutov taps out on Day 19 after weeks of exhausting nightly fire upkeep
• Nathan Olsen catches a nearly four-foot catfish fishing at night
• Kelsey Loper's morale is lifted by an encounter with a giant tortoise during a severe calorie deficit
• Katie Rydge builds an insulating mud dome shelter and sets rodent traps

Only three contestants remain, and hunting success becomes harder to come by for everyone. Kelsey Loper fends off a troop of roughly 40 baboons with bear spray and pushes through a failed hunting attempt despite fading upper-body strength. Katie Rydge, who hasn't landed a fish since Day 1, leans entirely on foraged plants to survive, while Nathan Olsen's stone shelter partially collapses on Day 24 even as his fishing keeps producing catfish.

• Kelsey Loper uses bear spray to drive off a troop of roughly 40 baboons
• Katie Rydge, fishless since Day 1, survives on foraged buffalo thorn leaves, acacia seeds, wormwood, and wild garlic
• Nathan Olsen's stone shelter walls partially collapse on Day 24 due to weak placement
• All three remaining contestants report significant weight loss of 20 pounds or more

With food nearly gone for everyone, the three finalists take very different approaches to the endgame. Nathan Olsen finishes rebuilding his stone shelter with a clay-sealed roof and admits to feeling homesick even as he embraces the solitude. Kelsey Loper, no longer able to draw her bow, turns to fishing with maggots for bait as her catch rate dries up, while Katie Rydge treks four miles east in search of mussels and fresh game.

• Nathan Olsen completes a rebuilt stone shelter with a termite-mound-clay waterproofed roof
• Kelsey Loper can no longer draw her bow and shifts fully to fishing with maggots as bait
• Katie Rydge treks roughly four miles toward the coast, nicknamed 'The Promised Land,' searching for mussels
• Kelsey marks her mother's birthday by eating her last piece of jerky

In the finale, the three remaining survivalists reach their physical limits after weeks of near-starvation. Katie Rydge, unable to secure reliable protein despite extensive foraging, chooses to tap out on Day 28 rather than risk further harm. Kelsey Loper follows on Day 33 after malnutrition brings on heart palpitations and shortness of breath, leaving Nathan Olsen to be declared the winner on Day 34 following an emotional surprise visit from his son during a medical check.

Out this episode: Katie Rydge (day 28), Kelsey Loper (day 33, medical)

• Katie Rydge taps out on Day 28 after losing about 31 pounds
• Kelsey Loper, down about 27 pounds, taps out on Day 33 after developing heart palpitations and shortness of breath
• Nathan Olsen's son Isaiah surprises him during a medical check, one of the finale's most emotional moments
• Nathan Olsen is declared the Season 12 winner on Day 34, the season's longest-lasting contestant, taking home $500,000
