Quick Facts

Tip: Book the earliest tour for calmer groups and the most undisturbed photo opportunities.

Tickets & Tours

Choose between standard guided walks (easy) and extended tours (moderate) that go deeper. Prices vary by season and inclusions (helmet, lights). Families often prefer standard tours.

• Refunds: Many operators offer 24h flexible rescheduling.
• Language: English tours are common; inquire about other languages.

Getting There

• Self‑drive from Reykjavík via Route 39 → 428 (gravel in parts).
• Transfers are available from the city and the airport area.

What You’ll See

• Mineral color bands, skylight openings, and frozen drip features.
• Seasonal ice sculptures near skylights in winter.
• Textured lava walls and floor with stone crystals.

Best Time to Visit

• Winter: ethereal light shafts, ice formations; colder footing.
• Summer: mossy surroundings, stable walking; brighter skylights.

What to Wear

• Waterproof boots with good grip
• Warm layers + hat & gloves
• Lightweight rain shell
• No umbrellas inside the tunnel

Accessibility

The entrance walkway is maintained; inside, footing is uneven with stairs in places. Ask the operator about current conditions, handrails, and group size before booking.

Photography Tips

• Bring a headlamp to paint light onto textures.
• Use wide lenses (24–35mm eq.) and stabilize against railings.
• Expose for highlights around skylights; bracket if needed.

Pro Tips

• Arrive 15–20 minutes before tour start.
• Pack a small towel to dry lenses in winter.
• Respect marked paths; fragile formations break easily.
• Combine with the Golden Circle for an efficient day.

Bottom line: Book a guided tour, dress warmly, and let the geology and light do the talking — it’s a rare chance to walk inside a frozen river of rock.
