Walk across raw lava fields and climb the steep cone of Mount Keilir on the Reykjanes Peninsula. This 5–6 hour guided hike from Reykjavík offers rugged geology, coastal views and a hands-on introduction to Iceland’s volcanic edge.
Walk across raw lava fields and climb the steep cone of Mount Keilir on the Reykjanes Peninsula. This 5–6 hour guided hike from Reykjavík offers rugged geology, coastal views and a hands-on introduction to Iceland’s volcanic edge.
You set out from the low, black plains of Reykjanes and immediately feel the land’s blunt personality—jagged lava, compacted sand and moss that clings like a green memory. The trail pushes across flat fields for 30–45 minutes before Keilir’s conical silhouette draws closer, a steep dome rising from younger lava flows created by the Mid-Atlantic Ridge’s restless activity.

You set out from the low, black plains of Reykjanes and immediately feel the land’s blunt personality—jagged lava, compacted sand and moss that clings like a green memory. The trail pushes across flat fields for 30–45 minutes before Keilir’s conical silhouette draws closer, a steep dome rising from younger lava flows created by the Mid-Atlantic Ridge’s restless activity.
Keilir is a young volcanic landmark on the Reykjanes Peninsula, shaped by basaltic eruptions and glacial interactions over the last ice age. The area carries both Viking-era lore and modern geology: recent eruptions at nearby Fagradalsfjall have remade the skyline and given guides new lookout points to point out.
Culturally the route threads past grazing ground and fishing communities; you’ll pass compact lava ridges and hear the wind speak in open channels. Seabirds wheel offshore, and if you look closely the lava fields wear a fragile coat of moss that takes decades to form.
Practical guidance: expect a 5–6 hour outing with private transport from Reykjavík or Keflavík, a 45-minute approach walk, then a steep, loose-gravel scramble to the summit. The final section rewards with expansive views of the peninsula, glimpses of the capital, and a small guestbook at the top.
Bring sturdy boots, layers against sudden wind, and poles for the scree. Follow your guide, stick to the paths to protect the moss, and plan for changing weather—this is an active volcanic coast, and the land moves fast.
The tour runs about 5–6 hours door-to-door with roughly 3 hours on the trail; the approach is easy but the last ascent is steep with loose gravel and can be strenuous.
No technical climbing skills are needed, but hikers should be comfortable with uneven terrain and steep scree sections and have moderate fitness.
Tours may be canceled for poor weather; guides monitor wind and visibility since conditions on Reykjanes can change quickly.
This hike is not recommended for those with serious back, heart, or mobility issues; check with the operator about age and fitness limitations.
