Trail along the rim of dramatic Sumidero Canyon with sheer walls dropping 1,000m to the Grijalva River below. Viewpoints along the trail reveal spectacular canyon depths and crocodile-filled river far below.
Cañón del Sumidero is one of Mexico's most dramatic natural features — a gorge carved by the Grijalva River through the central highlands of Chiapas, with sheer walls dropping up to 1,000 metres from the rim to the river below. While the canyon is most commonly visited by boat from Chiapa de Corzo, the rim trail offers an entirely different perspective, following the canyon edge between a series of official miradoros (viewpoints) with vertiginous cliff-edge views across the full depth of the gorge.
The trail follows the paved road connecting five official viewpoints within Cañón del Sumidero National Park: La Ceiba, Los Chihuahuenses, La Coyota, El Tepehuaje, and La Atalaya. On foot, the route from the park entrance to La Atalaya viewpoint and back covers approximately 10 kilometres with around 500 metres of cumulative elevation gain as the road undulates between viewpoints. The walking surface is primarily asphalt, with dirt paths branching to cliff-edge vantage points at each mirador.
Each viewpoint offers a unique perspective on the canyon below. La Coyota provides the most direct view of the sheer south wall, while La Atalaya reveals the canyon's full length stretching toward the Chicoasén dam. The river far below is home to American crocodiles, howler monkeys, and numerous waterbirds visible with binoculars from the rim. Tour boats navigating the river appear as small white dots against the dark canyon walls on clear days.
The park entrance is located on the road to Copoya, about 12 kilometres from Chiapa de Corzo. A small entrance fee is charged at the gate. Most visitors drive between viewpoints; hikers walking the full trail have the road largely to themselves on weekdays, though vehicle traffic must be accounted for throughout. The canyon is managed by the Comisión Nacional de Áreas Naturales Protegidas (CONANP).
Shade along the road between viewpoints is sparse; midday sun at the exposed rim is intense in dry season. Water is not available on the trail itself — vendors near the entrance sell drinks but nothing is available at the miradoros. Carrying at least 1.5 litres per person is essential.

Tips for visiting
- Carry binoculars for spotting crocodiles on the river banks and waterbirds from the canyon rim — the river wildlife is a highlight.
- The canyon is most photogenic in the morning before 11 a.m. when shadows reveal the wall depth; afternoon haze reduces visibility considerably.
- Consider hiring a taxi to drive the return leg from La Atalaya if the full 10-kilometre road walk in midday heat feels excessive.
- A boat tour from Chiapa de Corzo combined with the rim trail on the same day gives both floor-level and aerial perspectives.
- Entrance fees are payable at the park gate; carry cash in Mexican pesos.
- Walk facing oncoming traffic on the road verge between viewpoints — vehicle traffic is light but present throughout the day.
When to visit
Morning visits before 11 a.m. offer the best light on canyon walls and the lowest temperatures at the exposed rim; November through April avoids rainy season haze.
Accessibility
The paved road connecting the five miradoros can technically be navigated by wheelchair, though the gradient between viewpoints is moderate and vehicle traffic is present. The cliff-edge viewing platforms at each mirador have railings but involve uneven ground transitions that are not fully wheelchair-friendly. The road walk between viewpoints is not stroller-friendly for the full 10-kilometre distance.
Frequently asked questions
How do I get to the Sumidero Canyon rim trail?
From Chiapa de Corzo, taxi or colectivo services run toward the Copoya road and park entrance. From Tuxtla Gutiérrez, the canyon rim is about 20 kilometres by car. There is no reliable public bus directly to the miradoros, so a taxi or private vehicle is the most practical option.
Can I combine the rim trail with a boat tour?
Yes, and this is the most rewarding way to experience the canyon. Boat tours depart from Chiapa de Corzo embarcadero throughout the morning and last around 2 hours. The rim trail is typically done in the morning or afternoon as a complement.
Are the canyon-edge viewpoints fenced?
The official miradoros have railings and viewing platforms. Between viewpoints, the canyon edge is unfenced and drops sheer — visitors must remain on the road and designated paths at all times, especially with children.
Is wildlife visible from the rim?
Yes. With binoculars, crocodiles are regularly visible on river banks during dry season. Spider monkeys and howler monkeys inhabit the canyon walls, and the river supports over 100 bird species including various herons and anhingas.
