Private Reykjanes Day Tour: Lava Tunnel & Blue Lagoon

This private 9-hour day tour takes you deep into the volcanic heart of the Reykjanes Peninsula, combining geological wonders with the ultimate geothermal spa experience. With hotel pickup and drop-off in Reykjavík included, your dedicated English-speaking guide handles every detail in a luxury vehicle equipped with Wi-Fi.

Your first stop is Raufarhólshellir — known as The Lava Tunnel — one of Iceland's longest lava tubes. Formed over 5,200 years ago, the cave's vivid mineral colours and dramatic formations make for an unforgettable underground adventure. A one-hour guided tour leads you through approximately 300 metres of ancient volcanic passage at a relaxed pace.

From there, the tour continues to the otherworldly landscape of Krýsuvík, where steaming vents and bubbling mud-pots paint a scene straight from another planet. Nearby, the powerful Gunnuhver geothermal area and the historic Reykjanesviti lighthouse offer striking views of Iceland's raw coastal and volcanic character.

The day culminates at the Blue Lagoon, where your premium entry is pre-included — no separate booking required. Soak in the iconic mineral-rich waters and enjoy the silica mud mask, two drinks of your choice at the swim-up bar, plus a towel and bathrobe, all included in your admission.

Your guide collects your group from your Reykjavík hotel in the morning in a comfortable, Wi-Fi-equipped private vehicle. The day unfolds at a relaxed pace across four distinct stops on the Reykjanes Peninsula.

• Raufarhólshellir (The Lava Tunnel): A one-hour guided tour through one of Iceland's longest lava tubes. The path covers around 300 metres of uneven, rocky terrain walked slowly with frequent stops.
• Krýsuvík: Walk among steaming fumaroles and vivid mud-pots in one of Iceland's most active geothermal areas.
• Gunnuhver & Reykjanesviti: Marvel at powerful geothermal vents and enjoy panoramic coastal views from Iceland's oldest lighthouse.
• Blue Lagoon: End the day soaking in the famous mineral-rich lagoon. Premium entry covers the silica mud mask, two drinks at the swim-up bar, and use of a towel and bathrobe.

Your guide returns you to your Reykjavík drop-off point in the afternoon or early evening, completing a full and varied day on the peninsula.

A private tour means the itinerary revolves entirely around your group — no shared coaches, no strangers, and no rushed schedules. Hidden Iceland operates this experience in a luxury vehicle with Wi-Fi, led by a knowledgeable English-speaking guide who brings each location to life.

Every major cost is bundled in: the guided lava tunnel tour, premium Blue Lagoon admission with extras, and door-to-door Reykjavík transfers. There is nothing extra to arrange or pay on the day. For families, couples, or small groups seeking a personalised and comprehensive introduction to the Reykjanes Peninsula, this tour offers exceptional depth and comfort in a single 9-hour day.
