Reykjavík: Raufarhólshellir Lava Tunnel & Northern Lights Small-Group Tour

This evening small-group tour combines two of Iceland's most compelling natural experiences: a guided walk through Raufarhólshellir, the fourth-longest lava tube in Iceland, followed by a countryside search for the Northern Lights.

Your expert guide collects you by minibus from your Reykjavík accommodation and drives you to Raufarhólshellir lava tunnel, located roughly 45 minutes from the city. Inside, you'll venture up to 900 metres into the cave, taking in dramatic lava formations and vivid volcanic colours under the light of your included headtorch. The cave section of the tour lasts approximately one hour and is rated very easy — suitable for most fitness levels and families with children aged 6 and above.

After the cave, the group heads into the Icelandic countryside in search of the Aurora Borealis. Your guide actively monitors conditions and positions the group for the best possible viewing. Whenever the lights appear, the guide photographs participants with the aurora — images you can access free of charge after the tour. Hot chocolate is served while you watch the sky.

The full experience runs approximately 5 hours. Because the Northern Lights are a natural phenomenon, visibility depends on weather and solar activity. If the aurora is not visible during your tour, you are entitled to join a future Northern Lights minibus departure free of charge — valid for 3 years with unlimited attempts.

Evening hotel pickup by minibus from your Reykjavík accommodation marks the start of your 5-hour adventure. The drive to Raufarhólshellir takes approximately 45 minutes through the Icelandic countryside.

• Your specialist cave guide leads the group up to 900 metres into the lava tube, pointing out striking geological formations and explaining how the cave was created by ancient volcanic activity.
• Caving helmets and headtorches are provided — simply dress warmly and wear sturdy ankle-supporting footwear.
• After the cave, the minibus continues into the countryside for the Northern Lights search. Your guide selects viewing locations based on real-time conditions.
• The guide takes aurora photographs of the group whenever the lights appear; these are available to download free of charge after the tour.
• Hot chocolate is served during the sky-watching portion of the evening.

The tour difficulty is rated 1 out of 5 — very easy. Minimum age is 6 years. All participants must sign a standard activity waiver before departure.

This tour pairs two bucket-list Iceland experiences into a single, affordable evening — making it one of the most practical options for visitors who want both underground geology and aurora hunting without booking two separate trips.

• Small-group format means personal attention from your guide and a more immersive experience than large coach tours.
• Mandatory hotel pickup is included, so there is no need to arrange your own transport to a meeting point.
• Northern Lights photos are taken by your guide and provided free — no photography skills required.
• Free rebooking for up to 3 years if the aurora is not visible gives genuine peace of mind.
