The Sierra Nevada del Cocuy holds Colombia’s largest remaining ice mass, a wall of snow peaks and hanging glaciers rising above the páramo of Boyacá in the Eastern Andes. El Cocuy National Park protects it — and it is one of the most strictly regulated trekking areas in South America. After a period of closure, the park reopened with day-use-only rules: no camping, no multi-day traverses, a closed circuit trail, and mandatory registration, insurance and guiding for every hiker. Know the rules before you go and you will find some of the most dramatic high-altitude day hiking on the continent.
The current rules, plainly stated
Registration at the Parques Nacionales (PNN) office in El Cocuy town, Güicán or Bogotá is mandatory — you will not be granted entry without it. Second, the mandatory rescue and accident insurance, purchased at the park office. Third, a certified guide accompanies you on the trails. The park limits daily capacity on each trail (reports put it around 80–140 hikers depending on the trail), so in busy periods go early and confirm availability the day before. Fees change periodically: entrance, insurance and guide hire are all paid separately, and the park office posts the current prices — budget for all three and carry cash, as the towns have limited card facilities. No camping or overnight stays inside the park are allowed, and you must be off the trails by late afternoon.
The three open trails
All three open routes are full, strenuous day hikes of roughly 8–10 miles round trip, taking most walkers 8–9 hours. The Laguna Grande de la Sierra route climbs through páramo studded with frailejones to a great glacial lake beneath the Ritacuba peaks — it is the classic first hike. The Púlpito del Diablo (Devil’s Pulpit) route heads for the snow line beneath the black granite outcrop of the same name, with views across to the El Toti glacier; experienced hikers with crampons and ice axes can push toward high objectives such as El Cóncavo (around 5,200 m) and Pan de Azúcar (around 5,120 m). The Valle de Lagunillas route explores a gentler glacial valley with lakes and waterfalls. Trailheads are reached by early-morning shared lorries and trucks from the towns — departure times change, so confirm them at the PNN office the evening before. Ranch cabins (cabañas) near the trailheads, such as around La Esperanza and the Púlpito sector, are the practical bases; they are basic, cold and without electricity, so bring everything you need for the day.
Getting there
Overnight buses connect Bogotá with the gateway towns of El Cocuy and Güicán; it is a long mountain journey, so book a comfortable seat and arrive with a day to spare. Both towns sit high and make natural acclimatization bases — spend at least one or two nights in town before attempting a hike. Your guesthouse or the PNN office can arrange the guide, paperwork and morning transport as a package.
When to go
The driest and clearest conditions generally fall in December–March, with a second drier window around July–August, though mountain weather is never guaranteed and afternoon cloud builds quickly. Start every hike early — around 6 am is the norm — because the equatorial sun is fierce at altitude in the morning and storms or white-outs can roll in by early afternoon. Nights in the towns are cold year-round, and snow can fall on the high trails in any month, so pack for winter conditions even on a sunny-season trip.
Altitude and safety
The day hikes reach roughly 4,400–4,800 m, and the pace feels much harder than the distances suggest from sea level. Acclimatize in town, hydrate aggressively, and treat headaches, nausea or unusual fatigue as signals to descend — your guide will make the same call. Sun protection is critical: sunscreen, sunglasses and a hat or buff, because UV at 4,600 m near the equator burns fast. Carry a full packed lunch and more water than you think you need, plus a filter or purification as backup; there are no facilities on the trails, only the provisions you carry in. A headlamp, rain shell, warm mid-layer and sturdy waterproof boots complete the non-negotiable kit.
Costs
Plan for the park entrance fee, the mandatory insurance and the guide fee as three separate costs, plus accommodation in town, meals and the morning transport into the park. Guides are typically hired per group, so teaming up with other hikers at your guesthouse cuts the per-person cost. Treat prices you read online as indicative — the PNN office is the authority on the day. Bring pesos in cash; ATMs in these small towns are unreliable and the park office does not take cards.
Practical tips
Buy your entrance and insurance the afternoon before your hike so you can catch the earliest transport. The towns reward an unhurried evening: simple restaurants, trout on many menus, and wood-fired warmth after a freezing day on the trail. Learn a little Spanish: outside the main guesthouses English is rare, and your guide’s safety briefing matters. Finally, respect the closures — the multi-day circuit and the glaciers above the snow line are off-limits for good reasons, and the park’s rangers do enforce the rules.
