Erta Ale — “smoking mountain” in the Afar language — is a broad, low basalt shield volcano rising only about 613 m above the floor of the Danakil Depression, in the Afar Region of north-eastern Ethiopia. It sits on one of the places where the African continent is slowly tearing apart, and that restlessness is what feeds it: an elliptical summit caldera, roughly 1.6 km long, holding two pit craters that have contained molten lava for most of the last half-century.
The southern pit is the famous one. For decades it held a persistent lava lake — a churning surface of black crust split by glowing cracks and fountains — one of only a handful anywhere on Earth. But the lake is not a fixed attraction. It has risen and overflowed, drained after the January 2017 flank eruption, re-formed, and changed again since; in some seasons visitors see open lava, in others only a deep glowing vent, steam and fresh flows. Treat what you see as a snapshot of a living volcano, and always ask your operator about current conditions before you book.
Top things to do at Erta Ale Caldera & Lava Lake
Watch the crater after dark
The whole point of the climb. After the night trek you reach the caldera rim around midnight, drop your bag at the stone shelters and walk the last few hundred metres across the caldera floor with a scout to the edge of the active pit. What you see depends entirely on the volcano’s mood — from a boiling lake to a glowing vent under a column of gas.
Stay for sunrise
Most groups sleep a few hours on the rim and go back to the crater at first light. Dawn is when you finally understand the scale: the black caldera, the fresh flows, the smoke drifting towards the neighbouring volcanoes of the Erta Ale range.
Read the lava fields
Around the caldera you walk over glassy pāhoehoe, ropy folds, lava tubes and fragile blisters that crack underfoot. Your guide will show you which surfaces are fresh — and which ones not to step on.
See the northern pit and spatter cones
The quieter northern pit crater and the hornitos (chimney-like spatter cones) scattered across the caldera floor are worth a look at dawn, when the light is soft and the heat has not yet returned.
How to get to Erta Ale Caldera & Lava Lake
- Only with a licensed tour. Independent visits are not possible in practice: the Afar regional authorities require a registered operator, local guides and armed Afar escorts. See our tour comparison.
- From Mekele: a full day’s drive down the escarpment and across the lowlands, the final stretch on a rough lava track to the Dodom base camp. Most 3-day tours start here — read our getting there guide.
- From Semera: the Afar regional capital is the nearest airport; tours from here reach the volcano via Lake Afrera, often on day one.
- The final ascent: around 10 km on foot from base camp, roughly three hours, walked at night.
Insider tips
- The lava lake changes. Ask your operator — in writing — what recent groups have seen, and do not rely on photos from past years.
- Stay well back from the edge unless your scout says otherwise. Crater rims overhang and collapse, and fresh crust can be hollow.
- Bring a face mask or buff: when the wind turns, sulphur dioxide can be choking. Contact lens wearers should pack glasses.
- Use a tripod or brace your camera on a rock: night shots of the glow need a slow shutter speed.
- Remember it is an active volcano in a remote place. If the guides say the group must turn back, turn back.
Best tours that include Erta Ale Caldera & Lava Lake
These licensed expeditions are the practical way to reach Erta Ale Caldera & Lava Lake — transport, permits, Afar escorts and meals are all arranged for you:
3-day expedition from €396 2-Night 3-Day Danakil Depression Tour without Flights
The most-reviewed Erta Ale trip on GetYourGuide and the classic three-day loop: the volcano and its crater at night, Lake Afrera (also called Lake Giulietti), the salt flats and the colours of Dallol. Flights are not included, which keeps the price down if you are already in the north or want to book your own.
- Night hike to the Erta Ale crater rim
- Dallol’s sulphur springs and the Asale salt flats
- A float in hypersaline Lake Afrera
3-day expedition from €396 Mekele: 3-Day Danakil Depression Tour & Volcano
A straightforward three-day circuit from Mekele, the traditional starting point for the Danakil. You drive down from the highlands to the salt plain, cross the lava fields to the volcano, walk up to the rim for the night and finish at Dallol before climbing back to Mekele.
- Round trip from Mekele with 4x4 transport
- Sunset, night and dawn at the Erta Ale caldera
- Dallol hydrothermal field and the salt caravans
3-day expedition from €396 From Semera: Danakil Depression 3-Day Tour
Semera, the capital of the Afar Region, is the closest airport to Erta Ale, and this well-rated three-day tour uses it to reach the volcano from the south along the shore of Lake Afrera — shorter drives on day one than the classic Mekele route.
- The southern approach via Lake Afrera
- Overnight at the Erta Ale crater
- Salt flats and the Danakil landscapes
