Things to do at Sierra Negra Volcano
1. Sierra Negra Hike
Hands down the most popular Sierra Negra activity is hiking the trail up to the crater rim. The views from the peak are spectacular, both looking into the crater and enjoying panoramic vistas of Isabela island and beyond.
The trek to the lookout is rated easy-moderate. A 1.5km dirt trail rises steadily from 900m, up to 1,100m above sea level. The only real challenges to confront are the mud (in rainy season), and your own fitness and energy levels.
For an extra dose of adventure, trek beyond the Sierra Negra Volcano lookout (mirador), to visit the parasitic vent volcano - Volcan Chico. The incredible lunar landscapes are otherworldly, while lava ovens, and white, waspish fumaroles let off steam. On a clear day, hikers can also enjoy panoramic views of Darwin Volcano, and Santiago, Fernandina, and Pinzón islands.
The 1.5km trail beyond the lookout to Volcan Chico is a little more challenging due to the uneven, rock-strewn surfaces, and hot temperatures without shade. Be sure to carry lots of water and use sun protection here.
2. Sierra Negra Horse Riding
If the trek sounds like hard work, why not rent a horse up to the Volcan Sierra Negra lookout? At the time of writing the extra cost (on top of the regular tour price) is approx $30 per person. Jump in the saddle, and enjoy the lush highlands scenery as your horse plods along the trail.
3. Picnic under the old Jaboncillo Tree
One of the best rewards after the hot Sierra Negra hike is to enjoy a picnic under the shade of an old Jaconcillo (soapberry) tree. Close to the Sierra Negra lookout, wooden benches provide a welcome rest under the giant branches. Don’t be surprised if native Galapagos birds, like Darwin finches, hop right up to pick at your sandwich crumbs.
The jaboncillo tree species is of interest in its own right. The tree’s nuts can be used as soap with sliced open and mixed with water to form a lather. Native Americans and other indigenous cultures throughout the world have used this very fruit for washing over the centuries.
4. Bird watching
In terms of wildlife, the Sierra Negra trail is of most interest to bird watchers. Mockingbirds and different species of Darwin finch are common sightings, hopping around in bushes and scrub. Eye-catching red vermillion flycatchers and yellow warblers will also sometimes make a welcome appearance.
Also, keep your eyes on the sky, occasionally one can spot Galapagos hawks majestically soaring the thermals high above.

From a Galapagos destination expert todayPracticalities for visiting Sierra Negra Volcano
- A reasonable level of fitness is required for the Sierra Negra hike & Volcan Chico trail. Paths can be muddy and rocky, with uneven surfaces, so go prepared. Hiking poles can be a good idea for extra stability.
- Expect a mix of different weather on the trek. Early mornings can be quite chilly on route to the Sierra Negra trailhead. But temperatures soon become hot while hiking under a strong sun. This is especially true during the warm & wet season from December through to May. As the name suggests, rain showers (sometimes heavy) can also sometimes be expected.
- Recommended clothing includes comfortable walking shoes or trekking sandals (open-toe sandals are not suitable), shorts or light trekking trousers, a t-shirt or light long-sleeved shirt, light rain jacket.
- What else to bring along? Sun protection (sunglasses, hat, sunblock), water bottle (at least 1-2 liters), energy snacks, insect repellent, camera/cellphone.
Fun Sierra Negra Volcano Facts
Why is the volcano called Sierra Negra?
Sierra Negra translates to English as Black Mountain, named after the dark and black colorings of the old lava flows inside the crater.
How big is Sierra Negra Volcano?
While Sierra Negra’s height of 1,124metres might not be much to shout about, it more than makes up for it in mass!
Sierra Negra has the largest caldera of all of the Galapagos volcanoes, and is one of the largest volcanic craters on the planet. Her circumference measures a huge 30km (19miles), a fact that can be fully appreciated from the Sierra Negra Volcano viewpoint. It’s impossible not to be impressed by the sheer magnitude of the caldera.
Perhaps surprisingly though, Sierra Negra is also the shallowest of the Isabela island volcanoes, measuring in at just 100m deep in places.
When was the last Sierra Negra eruption?
It’s fair to say that Sierra Negra Volcano rarely sleeps. Her most recent eruption was in the summer of 2018, and before that in 2005. In fact since the 1950’s there has been on average one eruption every decade. This is good news for tourists though, as there are lots of young lava flows (both A’a and Pahoehoe) to see, and usually small smoking fumeroles too.
What type of volcano is Sierra Negra?
Sierra Negra is a large shield volcano. It was formed through many successive eruptions of very fluid, low viscocity lava. These thin flows spread quickly, far and wide, before solidifying, hence the long and broad shape of the resulting volcano.
Shield volcanoes are so named because they look like a warrior’s shield lying flat on the ground.
For more information about the geology and volcanic origin of the archipelago, check out our Galapagos Volcanoes blog post.
How old is Volcan Sierra Negra?
Geologists estimate Sierra Negra Volcano to be approximately 535,000 years old. Calculations are based on the volume of the volcano (588 km3), together with historic eruption rates.
