Volcan Cosigüina

Volcán Cosigüina is a large stratovolcano in western Nicaragua, located in the Volcán Cosigüina Nature Reserve. It can be climbed in a single day, offering panoramic views of the Pacific Ocean and three countriesː Nicaragua, El Salvador and Honduras.

The volcano and its slopes lie in the Volcán Cosigüina Nature Reserve. The small, quaint and out of the way town of Potosí is the local hot-spot and a good base for exploring the volcano. You can either hike up the mountain or drive to the parking lot near the top. From the parking lot, it's only a 1-km hike to reach the summit.

The volcano's most recent eruption was in 1859, but it's much more famous for an eruption in 1835 that was the world's third largest volcanic eruption, spewing ash and hurling rocks as far north as Mexico and as far south as Colombia.

The volcano has been dormant for over 150 years, so vegetation has taken over the slopes wherever vegetation can keep a foothold. Much of the hike to the top will be under the cooling protective cover of the forest canopy. The volcano has a height of 872 meters above sea level. The crater has a green lake in it that is filled from rainfall.

It's always hot and humid at Cosigüina. Light clothing is best, but you'll want sturdy boots, moisture absorbing socks, and a hat to keep the fierce sun at bay.

From Chinandega, you can easily drive to the area, with the main road going to Potosí on the eastern side of the volcano. Local roads surround the volcano on its northern, eastern and southern sides, but you cannot drive around the whole volcano. From the southern side, you can drive to the parking lot near the top, from which there is only a 1-km hike to reach the summit.

There are buses to Potosí from Chinandega and León. In Leon's El Mercadito bus station, look for the bus with "Potosí" at the top of the windshield. It's a direct bus, but with lots of stops to let people on and off: plan on 5 to 6 hours to reach Potosí. From Potosí, it is a 9-km hike up to the summit.

From La Unión in El Salvador, there is a ferry that crosses directly to Potosí. The trip across the bay takes at least 2 hours and costs US$65.

Hike or drive the paved park road to the summit (large parking lot available there).

• Gorgeous views of Nicaragua, El Salvador, Honduras and the Pacific Ocean from the top of the volcano.
• A beautiful volcano crater

• Hikeː The trail starts in the town of Potosi. It's just under 9 km each way (17.7 km out and back). The hike is fairly gentle, with the only real steep section being the last kilometer as you approach the summit. There is also a rim trail that circles the caldera, which is a 1.5-km hike and has one crumbling section that may be too dangerous to walk across. There is no marked trail from the rim to the bottom of the caldera, but visitors can descend into the crater if they have ropes and are fit enough to pull themselves back up. You can find GPS routes on the Maps.Me app, or you can hire a local guide for about US$30 (recommended because the guides have local knowledge, so you'll get more out of the experience, plus they will attend to safety issues, take care of paying the park entry fee, etc.).
