Is Kirkjan worth the extra Dimmuborgir walk?
Kirkjan is worth seeking out if you are already walking Dimmuborgir and want the lava field's clearest cave-like formation. It is too narrow to plan as a standalone detour.
Think of Lava Church Cave as a decision inside Dimmuborgir, not a separate destination competing with the whole Lake Mývatn area. The formation gives the walk a specific goal: a dark, church-shaped lava arch with rough rock steps and a small enclosed feeling.
It works best when your day already includes Lake Mývatn and you want one close-up lava formation rather than another wide viewpoint. It works poorly when the route is already crowded with waterfalls, geothermal stops, and long driving.

What the Lava Church actually looks like
The appeal is not a deep guided cave. It is the way the lava opening frames a shadowy, vaulted space that can feel unexpectedly architectural.
From outside, Kirkjan reads as one of many dark lava openings in Dimmuborgir. Step closer and the shape becomes more memorable: a rough arch, a low chamber, jagged walls, and enough height to understand why visitors compare it to a small stone church.
That is also the limit of the stop. Travelers expecting a long lava-tunnel tour should compare places such as Lofthellir instead. Kirkjan is a short, visual formation inside an outdoor lava-field walk.
How Kirkjan fits into a Mývatn volcanic day
Kirkjan belongs in a Mývatn day when Dimmuborgir is your lava-walk stop and nearby places each have a different job.
Grjótagjá gives a quick lava-cave glimpse with geothermal water, Skútustaðagígar gives a gentler pseudocrater walk, and Hverir Geothermal Area gives steam, mud, and sulfur color. Kirkjan is the formation-focused reason to stay longer inside Dimmuborgir.
If the day stretches toward Goðafoss or Dettifoss, be selective. Kirkjan adds texture, but it should not steal the relaxed pace that makes the Mývatn cluster work.
| Choice | Use it when | Better move |
|---|---|---|
| Walk to Kirkjan | You want the most memorable formation in Dimmuborgir. | Give Dimmuborgir real walking time. |
| Keep it optional | Weather, footing, or daylight makes the day feel tight. | Use a shorter Dimmuborgir loop. |
| Skip the specific formation | You only need one quick volcanic stop. | Choose the broader Mývatn stop that fits best. |
When the shorter lava-field loop is enough
The shorter Dimmuborgir loop is enough when the day needs a quick volcanic texture stop rather than a named-formation objective.
This is the practical tradeoff. Kirkjan gives you a stronger memory of Dimmuborgir, but it is still one formation in a wider lava field. If you are tired, the weather is deteriorating, or the Mývatn plan already has several stops, a shorter walk can be the better decision.
Protected lava, weather, and path checks
Dimmuborgir is protected for its unusual lava formations, so the right visit is a marked-path walk that adapts to footing and weather.
The protection context matters because the lava shapes are the attraction. Stay on marked paths, avoid climbing on fragile formations, and treat vegetation and rough rock as part of the site rather than obstacles.
Weather can change the feel of a simple walk. Snow, ice, wind, or low light can make Dimmuborgir less casual, so check official visitor information, road conditions, weather warnings, and safety guidance before building the stop into a tight North Iceland day.

Common Kirkjan Cave questions
These are the practical questions that usually decide whether the formation deserves more time than a quick Dimmuborgir look.
Is Kirkjan separate from Dimmuborgir?
No. Kirkjan, or Lava Church Cave, is a named formation within Dimmuborgir, so plan it as part of the Dimmuborgir walking area.
Is Kirkjan a guided lava cave?
No. Kirkjan is a cave-like lava arch on a marked outdoor walking route, not a long guided lava-tunnel experience.
Should I choose Kirkjan or the shorter Dimmuborgir loop?
Choose Kirkjan when the formation itself is the goal. Use a shorter loop when time, weather, footing, or daylight makes the longer walk less appealing.
