ESJA IN SHORT

Esja is a volcanic mountain range across the bay from Reykjavík, about 10 km from the city in a straight line, with its highest point at 914 m. The popular hike to the large rock Steinn is about 6–7 km return, takes most people 2–4 hours, is free, and starts at a car park in Kollafjörður beside Route 1.

About Esja

Esja is not one mountain but a range of basalt and tuff, formed in the Pleistocene, with the western part around 3.2 million years old and the eastern part around 1.8 million. The highest point, Hábunga, is 914 m. Two well-known summits are Þverfellshorn (780 m) and Kerhólakambur (851 m). It is the closest proper hiking mountain to Reykjavík and the backdrop to the city skyline.

Almost everyone walks the marked path to Steinn, a big rock that is the usual turning point. The path is steep in places but needs no technical skill in good summer conditions. Beyond Steinn the climb to Þverfellshorn is steeper and more exposed, with handrails on the final section, and the route on to Hábunga crosses a rocky plateau with no signs or clear path, so it is only for experienced hikers.

Locals call the mountain Esjan, which simply means 'the Esja', and it is their favourite everyday hike. On a fine evening you share the path with people from Reykjavík walking or running up after work, which also means there is always someone to ask if you are unsure of the way. Most people hike without a guide, because the main routes are clear.

The mountain has changed little since the volcanic activity here ended, apart from the work of Ice Age glaciers that carved its flat-topped shape. In summer the lower slopes are covered in lupin and wildflowers, and there is plenty of birdlife along the trail, so keep a camera to hand.

How to get to Esja

By carLeave Reykjavík on Vesturlandsvegur (Route 49), which becomes Route 1, and follow it north through Mosfellsbær to the small fjord Kollafjörður. At the north-east corner of the fjord, 5–6 km north of Mosfellsbær, take the signposted exit on the right to the large car park at the foot of the mountain. The drive takes about 20 minutes, the road is paved and any car can reach it.
By public transportStrætó bus route 57 runs from Mjódd in Reykjavík to the Esja hiking centre stop in about 30 minutes. From the city centre, take bus 15 from Hlemmur towards Mosfellsbær, get off at Háholt and change to bus 57. Check the timetable before you go, as route 57 runs far less often than city buses, and note the time of the bus back.
ParkingThere is a car park at the trailhead, the usual starting point for the Steinn route. Toilets are at the trailhead.

Hiking Mount Esja: the routes

The paths are well marked, and signboards at the start show how difficult each route is, which makes it easy to pick one that suits you. If you are new to hiking, choose the simple route and leave the steeper summits to experienced walkers.

To SteinnThe standard hike. A marked path climbs from the car park to the big rock Steinn, about 6–7 km return and 2–4 hours for most people. Several path variants of different steepness lead to the same point.
Þverfellshorn (780 m)The peak directly above Steinn. The last section is steep and rocky, with chains and handrails, and is not for anyone uneasy with heights. In snow or ice it is for experienced, equipped hikers only.
Kerhólakambur (851 m)A higher and less walked summit further west on the mountain. It is a longer and more demanding day than the Steinn route.
Hábunga (914 m)The highest point of Esja lies about 3 km north-east of Þverfellshorn, across a stony plateau with no clear path. You need good visibility and navigation skills.

The hiking season is summer. Esja looks its best from the city when it is capped with snow, but hiking it when it is snow-covered is not recommended unless you have winter experience and equipment. Ice, rain and thick fog are all common, and the weather can turn at any time, so check the forecast and wear sturdy boots whatever the season.

Know your own limits. Turning back at Steinn is what most people do, and the view over Reykjavík and Faxaflói bay from there is already wide.

Best time to visit Esja

Summer (June–August)The easiest and safest time to hike, with long daylight and usually dry paths.
WinterThe route stays open all year, but it is often icy and snow-covered, and ice spikes are needed. Avalanches on the upper slopes have killed hikers in past winters, the most recent in 2020, and another climber died on the mountain in 2025.

Check the weather and avalanche information on vedur.is and safetravel.is before any winter hike, and turn back if conditions look uncertain.

Safety and practical tips

  • Wear proper hiking boots; the path is loose and rocky in sections, and waterproofs matter, as weather changes quickly.
  • Weather on Esja can change quickly, even when it looks calm in Reykjavík. Bring water, food and a charged phone.
  • Stay on the marked path to protect the vegetation and avoid rockfall and landslide risk.
  • In winter, bring ice spikes and check safetravel.is and vedur.is first, or skip the hike if conditions are poor.
  • Steinn is a sensible turning point for most hikers. The ridge beyond it is for experienced climbers only. Call 112 in an emergency.

Facilities and accessibility

There is a large car park and toilets at the trailhead. Right below the slopes, Esjustofa has a café-restaurant where you can sit down after the hike; opening hours vary by season.

Where to stay near Esja

Esja is so close to the capital that most people stay in Reykjavík, with its wide choice of hotels, guesthouses and a campsite, and come out for half a day. Mosfellsbær, on the way, is closer still and has simpler places to stay on the edge of the city. Esja also works as a first or last stop if you are driving the Ring Road.
