La Piedra del Peñol is a granite dome about 200 meters tall that rises beside the Peñol-Guatapé reservoir, roughly 2 hours east of Medellín. A staircase of around 740 steps zigzags up a crack in its side to a lookout over the lake's maze of islands. It's the main reason most people make the Guatapé day trip, and it suits anyone who can handle a long, steady climb.
What it's like
You see La Piedra long before you reach it. The rock is a smooth, dark dome of granite that pokes out of green hills on the edge of the Peñol-Guatapé reservoir, and it's big enough to dominate the whole landscape. Geologists describe it as part of the Antioquia Batholith, a huge body of granite that formed deep underground. The rock survived because it's less cracked than the stone around it, so it wore away more slowly.
The climb follows a staircase built into a natural fissure on one side. It's a single long zigzag of concrete and brick steps with handrails, broken by small landings where people stop to catch their breath. The management counts 740 steps; you'll see other numbers quoted, depending on where people start and stop counting. At the top there's a lookout tower, snack stands and souvenir stalls.
The view is the point. Below you, the reservoir spreads out in every direction as a tangle of blue arms, peninsulas and small wooded islands. It's a human-made landscape: the public utility Empresas Públicas de Medellín (EPM) flooded the valley for a hydroelectric project built in 2 stages in the 1970s, and the old town center of El Peñol was demolished and moved to make way for it.
The painted letters
On one face of the rock you'll spot a huge white "G" and a single vertical stroke. They're the start of the word "GUATAPÉ". The rock sits in the municipality of Guatapé, but the neighboring town of El Peñol also claimed it. When people from Guatapé began painting their town's name on it, residents of El Peñol turned up to stop them, and the letters were never finished. You'll hear the story from guides and boat captains around the lake.
Tips for the climb
- Go early. Mornings are usually clearer and less crowded, and the stairs get busy on weekends and Colombian public holidays.
- Take it slowly. The top sits at roughly 2,135 meters above sea level, higher than Medellín, and the steps are steep in places. Most fit people manage it in 20 to 40 minutes with breaks.
- Bring water, a hat and sunscreen. There's little shade on the staircase.
- Plan for the weather. Afternoon clouds and showers are common in the rainy months, and they can hide the view.
- Wear shoes with grip. The steps can be slippery after rain.
If you'd rather not climb, the base area has restaurants with views of the rock and the lake, and boat trips leave from Guatapé's waterfront.
Who it suits (and who it doesn't)
It's a great stop for most travelers who are reasonably fit, including older kids. It's not a good fit if you have knee or heart problems, a strong fear of heights or limited mobility, as there's no lift or cable car to the top.
Getting there
Buses for Guatapé leave Medellín's Terminal del Norte, next to Caribe metro station, about every hour from early morning, run by Sotrapeñol and Sotrasanvicente. The ride usually takes around 2 hours and can take longer on weekends. Ask the driver to drop you at La Piedra; from the main road, it's about 1 kilometer uphill to the base, or you can take a tuk-tuk. Guatapé town is about 2 kilometers away, so it's easy to combine the climb with lunch and a walk around the town. Most visitors do both in one day. See our full Guatapé day trip guide.
Frequently asked questions
How many steps are there to the top?
The management uses a count of 740 steps. You'll see other figures, usually a bit lower, because people measure from different points.
How long does the climb take?
Most people take 20 to 40 minutes to go up, with rests. Allow 1 to 2 hours for the whole visit.
Can I visit La Piedra and Guatapé on the same day?
Yes. They're about 2 kilometers apart, and the Medellín buses stop near both. That's how most people do it.
Is the rock in Guatapé or El Peñol?
It's in the municipality of Guatapé, although El Peñol has long claimed it too. That dispute is why the painted letters on the rock were never finished.
