Nevado de Santa Isabel

Nevado de Santa Isabel (Poleka Kasué)

Information

Elevation: 4.945 m
Country: Kolombia (CO)
Location / Range: Cordillera Central, Andes (busur vulkanik Andes Utara), di dalam Parque Nacional Natural Los Nevados — perbatasan Departemen Caldas, Risaralda, dan Tolima
Mountain type: Kompleks vulkanik berselimut gletser dengan tiga puncak utama (El Cisne, Santa Isabel, El Quindío) pada kisaran 4.923–4.965 m. Wikipedia berbahasa Spanyol menyebutnya kompleks stratovolkanik andesitik yang tidak aktif, sementara Smithsonian Global Volcanism Program mengklasifikasikannya sebagai gunung api perisai dengan letusan terakhir yang diketahui sekitar 850 SM.
Volcanic?: Yes — volcano
Coordinates: 4.8167, -75.3667
Difficulty: Sampai bekas batas gletser jalurnya non-teknis. Sendero del Cambio Climático (dulu Borde de Glaciar) naik sekitar 600 m dari 4.100–4.150 m ke 4.750–4.800 m dan ditempuh sekitar tiga jam; beratnya datang dari ketinggian, dingin, dan angin, bukan dari gerakan teknis. Untuk mencapai puncak sekitar 4.950–4.965 m, operator masih mensyaratkan crampon, piolet, harness, dan helm, serta bergerak dalam tali beregu; satu panduan pendakian Kolombia menilainya Nivel 3 (Exigente/Técnico). Seluruh kegiatan wajib dipandu.
Best Season: Mengikuti pola dua musim kering Andes Kolombia: Januari–Februari dan Juli–Agustus memberi hari paling cerah. Di luar jendela itu páramo basah, berkabut, dan sering diguyur hujan atau salju basah.
Permits & Rules: Masuk lewat Parque Nacional Natural Los Nevados dengan reservasi di muka — umumnya minimal tiga sampai lima hari sebelumnya melalui kantor kontrol Potosí, El Cisne, atau Brisas — dengan kuota harian terbatas (sekitar 68 orang untuk jalur Conejeras). Tarif resmi yang diumumkan saat pembukaan kembali 2023: 10.500 COP untuk usia 6–25 tahun, 19.500 COP untuk dewasa warga negara, dan 54.000 COP untuk asing non-residen, ditambah sekitar 15.000 COP biaya layanan dan 5.000 COP asuransi penyelamatan; catatan pendaki 2025–2026 menyebut angka 23.500 COP untuk warga Kolombia dan 65.000 COP untuk asing. Naik ke gletser atau masuk kawasan lindung tanpa otorisasi, perlengkapan memadai, dan pendampingan pemandu berizin dilarang. Operator harus berizin taman dan pemandunya bersertifikat.
Hazards: Ketinggian adalah risiko utama: titik awal jalan kaki sudah berada di sekitar 4.100–4.150 m sehingga tubuh nyaris tidak punya kesempatan beraklimatisasi bertahap, dan penyakit ketinggian bisa muncul cepat. Suhu turun ke kisaran 5 sampai minus 2 derajat Celsius pada malam dan dini hari, dengan angin serta hujan beku. Medannya páramo becek yang membeku semalaman, moraine berbatu lepas, serta pasir dan abu vulkanik yang membuat pijakan mundur. Sisa gletsernya kini tipis dan retak-retak akibat pencairan cepat sehingga makin tidak dapat diandalkan. Jalur tidak bertanda dan tidak ada layanan penyelamatan cepat di sekitarnya. Terakhir, akses bisa ditutup mendadak: seluruh taman ditutup pada 2 April 2023 setelah Servicio Geológico Colombiano menaikkan status Nevado del Ruiz ke alerta naranja, dan baru dibuka kembali pada 10 Agustus 2023.

Description

Nevado de Santa Isabel (4,945 m) stands in Colombia's Cordillera Central inside Parque Nacional Natural Los Nevados, exactly where the departments of Caldas, Risaralda and Tolima meet. In the Quimbaya language it is known as Poleka Kasué. It is not a single cone but a complex with three main summits between about 4,923 and 4,965 metres, and the Smithsonian Global Volcanism Program records its last known eruption at roughly 850 BCE — so this is a practically dormant volcano, and what makes it significant today is not its volcanic activity but its vanishing ice. The glacier's retreat figures are among the most dramatic in the tropics. From roughly 27.8 square kilometres in the second half of the 19th century, the ice fell to 9.40 km² in the 1950s, 1.91 km² in 2010, 0.29 km² in 2022, and just 0.16 km² in 2024 — a loss of more than 94 percent in a century, and 45 percent in the last two years alone. IDEAM projects the glacier will disappear within about five years, while the Spanish Wikipedia cites forecasts of its loss before 2030. What remains is fragmented into small relicts, the largest on the northern dome. The Conejeras glacier, part of this complex and one of the most closely studied tropical glaciers in Colombia, was declared extinct in January–February 2024 after eighteen years of uninterrupted monthly monitoring by IDEAM. Nationally, Colombia lost 6.8 percent of its glacier cover in just two years, from 33.09 to 30.83 square kilometres. That is why the main trail changed its name. What was once the Borde de Glaciar is now officially the Sendero del Cambio Climático, with interpretive panels along the way marking where the ice edge stood in each decade since the 1960s. Hikers in 2025 and 2026 record the same flat conclusion: the glacier, in the sense most people picture, is essentially gone. Access to this mountain has an unusual character. Four-wheel-drive vehicles carry visitors from the Potosí sector at about 3,850–4,000 metres, or from the El Cisne visitor centre at 4,152 metres — the highest visitor centre in Colombia — to a walking start at roughly 4,100–4,150 metres. Almost all the elevation is gained by engine, and hikers begin walking straight into very thin air. Only about 600 vertical metres remain, but this is where many people struggle: there is no technical movement at all, yet breath, cold and wind cut walking pace sharply. The route crosses páramo, a high tropical ecosystem covering only about one percent of Colombia, full of frailejones, mountain wetlands, lagoons such as Laguna Verde and Laguna del Otún, and stretches of moraine and volcanic ash. Visits are tightly regulated — advance reservation, daily quotas, mandatory park-licensed operators with certified guides — and can be cancelled at any time if activity at nearby Nevado del Ruiz rises or if the park closes sectors for ecosystem regeneration. For many hikers the appeal of Santa Isabel today is frankly elegiac: visiting one of Colombia's last ice masses before it is gone for good.

Routes

Puncak Nevado Santa Isabel via El Cisne (dua hari, melintasi sisa gletser)

Exigente/teknis — butuh crampon, piolet, harness, dan helm

12.00 km +813 m Dua hari — hari 1 perjalanan darat, jalan aklimatisasi, dan menginap di refugio; hari 2 sekitar 6 jam ke puncak lalu turun

The full summit version usually runs from the El Cisne visitor centre at 4,152 m, the highest visitor centre in Colombia, reached by about three hours of driving from Manizales or Villamaría. Day one is deliberately given to acclimatisation: a long 4x4 transfer, an easy walk above 4,000 m, and a night in the refuge — or camping near Laguna del Otún on some operators' variants — with night temperatures around 5 down to −2 °C. Day two starts very early: parties are typically woken around 04:00–04:30 for breakfast, then driven to the trail start and walking by 06:00–06:30 with headlamps. The route crosses páramo and moraine with views over Laguna Verde, reaching the ice edge at roughly 4,693–4,800 m after 2.5–3 hours. There participants fit ice gear — crampons, axe, harness, carabiners, helmet, gaiters — and move roped across the remaining glacier for about 1.5–2 hours to the summit at 4,950–4,965 m. That is roughly six hours up and over 800 m of net gain from El Cisne. The usual guide ratio is one certified guide per three participants. The alternative entry is from Potosí, about four hours from Santa Rosa de Cabal in Risaralda, leading to the southern summit where far less ice remains. The main hazards are altitude sickness, extreme cold, fast-changing weather, and residual ice that is thinning and cracking as the glacier retreats. The clearest months are January, February, July and August. Everything must go through a park-authorised operator, with daily quotas and advance reservation.

Sendero del Cambio Climático (dulu Borde de Glaciar) — Conejeras/Potosí ke bekas tepi gletser

Sedang — non-teknis, tanpa perlu pengalaman mountaineering, tetapi berat karena ketinggian

7.40 km +650 m ±3 jam naik, 2 jam turun (5–6 jam bergerak); dijual sebagai perjalanan sehari atau bagian paket dua hari

This is the most popular and most accessible route on Santa Isabel, and it now doubles as a climate-change interpretive trail. Visitors gather in the Potosí sector at about 3,850–4,000 m for breakfast and a mandatory briefing from PNN Los Nevados staff, then transfer by dedicated 4x4 to the Conejeras sector at roughly 4,100–4,150 m — practically all the altitude is gained by vehicle, so hikers start walking straight into very thin air. The walking section is about 3.7 km one way, roughly 7.4 km return, with around 600 m of net gain to 4,700–4,800 m; some operators and trip reports give about 8 km because drop-off points vary. The ground is classic high páramo: tussock grass and frailejones, wet muddy soil that freezes overnight, then loose rocky moraine, volcanic sand and ash that give back half a step, plus standing water and thin ice higher up. There is no technical movement; what drains people is breathing, wind, and temperatures that can fall to around −2 °C before sunrise. Interpretive panels along the trail mark where the glacier edge stood in each decade since the 1960s, and today's turnaround point is that former ice margin — hikers in 2025–2026 report ice surviving only as relicts on the northern dome. The route is capped at a daily quota of about 68 people, requires reservation at least three days ahead, and must be done with a park-licensed operator and certified guide. Suitable for reasonably fit hikers; not advised for people with heart conditions or hypertension.

Trek gletser Santa Isabel dua hari via Laguna del Otún (dari Pereira/Manizales)

Sedang — non-teknis, dengan penekanan pada aklimatisasi

6.60 km +600 m Dua hari — hari 1 berkendara ±3,5 jam plus jalan aklimatisasi ±3,5 jam dan berkemah; hari 2 dua sampai tiga jam ke tepi gletser lalu kembali ke kota sekitar pukul 17.00

A variant built around acclimatisation, well suited to hikers arriving straight from low elevation. Pickup is at 06:00 in Manizales or Pereira, followed by about 3.5 hours of driving into Parque Nacional Natural Los Nevados. The rest of day one is an acclimatisation walk of roughly 3.5 hours entirely above 4,000 m, through páramo — a rare tropical ecosystem covering only about one percent of Colombia — with frailejones, mountain wetlands and volcanic rock formations. The night is spent camping near Laguna del Otún, directly beneath the snow-capped summits; this is the hardest part for comfort, as temperatures drop near freezing and the wind off the high lake bites. Day two is a two-to-three-hour climb of about 3.3 km one way, roughly 6.6 km return, to the glacier margin, with around 600 m of net gain over rocky moraine and volcanic sand. The turnaround is direct contact with the ice — one of the last glaciers left in Colombia — before the group descends and returns to the city around 17:00. The operator provides bilingual guides in Spanish, English and French, and the Parques Nacionales entry fee is included; entering without a licensed guide is not permitted. Note that access to this whole sector depends on the park's status: a full closure ran from April to August 2023 when Nevado del Ruiz was raised to orange alert, and periodic closures for ecosystem regeneration remain routine.

Climbing Experiences

Trip reports on Nevado de Santa Isabel repeat several distinctive patterns. First, the height of the start: 4x4 vehicles deliver hikers to about 4,100–4,150 m, so walking begins in very thin air and almost everyone reports a far slower pace than expected — the gain is only around 600 m, yet the day still feels long. Second, the clock: parties are typically woken around 04:00–04:30 in the refuge, eat breakfast, and start walking by 06:00–06:30 with headlamps. Third, the cold: the recurring figures are 10–18 °C by day but 5 down to −2 °C at night and before dawn, with thermal layers and a waterproof jacket described as mandatory rather than optional. Fourth, the ground: boggy páramo that freezes overnight, rocky moraine, volcanic ash, standing water and thin ice higher up — no technical movement up to the ice edge, but footing that often slides back. Fifth, and most striking in recent accounts: the glacier is nearly gone. Interpretive panels along the Sendero del Cambio Climático mark where the ice edge stood in each decade since the 1960s, and hikers in 2025–2026 state it bluntly — ice survives only on the northern dome. Several creators openly frame their climb as a last visit before the glacier disappears entirely. Sixth, the rules: everyone stresses that a certified guide is mandatory and not a formality, because the route is unmarked, weather changes fast, and there is no rescue service nearby; reservations at least three days ahead and daily quotas apply.
