The El Cocuy Side-Quest: Why You Should Get Off the Bike on Oh Boyacá

You'll see it before you reach it. Somewhere between the switchbacks on the Soatá climb, the Sierra Nevada del Cocuy shows up on the horizon — a jagged white line above 5,000 metres that doesn't look real until you've been staring at páramo and canyon for two days straight. Almost 13 km² of ice. Colombia's largest glacier, and one of the last few left in the tropics at all.

Riding past it is one thing. Walking to its edge is another. If your Oh Boyacá itinerary has any slack in it, this is the side-quest worth building the slack around.

It's a Walk, Not a Ride

The bikes stay locked up in El Cocuy or Güicán town for this one. Parque Nacional Natural El Cocuy doesn't allow mountain biking inside the protected area, and honestly, you wouldn't want to pedal it anyway — the trails climb well above 4,000 m, and every gram of energy you have needs to go into your legs and your lungs, not your bike.

Budget three days in town for this, not one:

1. Day 1: Acclimatize. At 2,700 m, El Cocuy is exactly the kind of place Bikepacking.com's own Oh Boyacá route notes tell you to slow down: give your body a full day here before doing anything else.
2. Day 2: Park paperwork. Registration, insurance, the mandatory briefing. Tedious, but it's how the park keeps both visitors and the ecosystem safe.
3. Day 3: The hike. Seven to nine hours, up to the edge of the glacier and back.

If you're following the Oh Boyacá route, this is exactly where it fits: right around the San Mateo–El Cocuy–Güicán stretch, the route's own day-by-day notes suggest turning what's normally a quick pass-through into "a couple of nights in El Cocuy with an unloaded day loop." That's this side-quest.

What the Park Actually Requires

This isn't a park you wander into. Parques Nacionales Naturales de Colombia runs a tight system, and it's worth knowing the real rules before you show up:

• Entry fee: $107,000 COP per person for foreign non-residents. The ticket is valid for 4 days and covers all three authorized trails.
• A certified guide is mandatory. Nobody hikes solo here. You don't need to book one from abroad weeks in advance — the park office in El Cocuy or Güicán keeps its own list of approved guides, and that's where you arrange one once you're in town. It isn't an official requirement that your guide speaks English, so if that matters to you, ask specifically when you pick one from the list.
• Rescue and assistance insurance is mandatory, bought locally in El Cocuy or Güicán.
• You register in person and sit through a short mandatory briefing at the park office, at set times, before your hike day.
• Reserve your trail date ahead if you can. Daily capacity on each trail is limited. Guide and insurance pricing both vary, so it's worth asking around once you're at the office rather than locking in a price from home.

Hike Day

The schedule is fixed, and the rangers hold you to it:

• Entry window: 6:00–8:00 a.m.
• Latest start for your descent: 1:00 p.m.
• Everyone must be out of the park by 5:00 p.m.

You pick one trail, out-and-back, same day:

• Ritacuba — 14 km round trip
• Laguna Grande de la Sierra — 19.6 km round trip
• Lagunillas–Púlpito del Diablo — 15.6 km round trip

All three end at the same place: the edge of the ice, not on it.

The Glacier Is Sacred Ground — Treat It That Way 

The Sierra Nevada del Cocuy is sacred territory for the U'wa people, and the park protects the glacier itself with real seriousness. A few non-negotiables:

• You don't step on or touch the snow or ice. Every trail stops at the edge.
• The eastern flank of the range and the "Vuelta a la Sierra" trail are closed to visitors — U'wa territory, off limits.
• No mountain biking, no camping, inside the protected area.
• You stay with your guide, and you stay on the marked trail. Always.

 Getting Your Body Ready

You'll be walking above 4,000 m, and the altitude doesn't care how fit you are on a bike. A few things the park itself is emphatic about:

• Acclimatize for at least one full day before the hike.
• Hydrate hard, around 4 litres of water a day.
• SPF 50+ and UV-rated sunglasses. The glare off the ice burns faster than people expect.
• If you feel dizziness, headache, coughing, or shortness of breath: stop, tell your guide, and descend immediately if it doesn't pass. It can be the start of pulmonary or cerebral edema, and it's not something to push through.

What Goes in the Pack

• Layers: a thermal base layer, an insulating mid-layer, a waterproof shell.
• Rigid mountaineering boots — not running or cycling shoes.
• UV category 3–4 sunglasses and SPF 50+ sunscreen.
