Jokulsarlon Glacier Lagoon: Boat rides, day trips & Diamond beach 

What is Jokulsarlon Glacier Lagoon?

Jokulsarlon Glacier Lagoon is a glacial lagoon in southeast Iceland, where massive icebergs drift peacefully from Breiðamerkurjökull glacier toward the North Atlantic. Set at the edge of Vatnajökull National Park, the lagoon is filled with floating icebergs and crystal-clear waters, offering easy access to activities such as boat tours, kayaking, glacier hikes, and more. Read on to explore everything from history to must-do experiences and trip planning essentials.

What to expect on a Jokulsarlon day trip from Reykjavik

• Full-day tour (14–15 hours) from Reykjavik, covering Iceland’s scenic South Coast and ending at Jokulsarlon Glacier Lagoon.
• Comfortable transfers included with hotel pickup (when selected), free Wi-Fi, and an English-speaking guide throughout the journey.
• Drive along Route 1 (Ring Road) passing lava fields, coastal cliffs, glaciers, and black sand deserts.
• Stop at Seljalandsfoss, one of Iceland’s most iconic waterfalls, with the unique opportunity to walk behind it. Pause at Stjornarfoss, a lesser-known but picturesque waterfall tucked into a serene canyon.
• Visit Vik, a charming coastal village with dramatic views of the Reynisdrangar sea stacks (included in some tours).
• Arrive at Jokulsarlon Glacier Lagoon, where you’ll spend approximately 90 minutes exploring the lagoon and its surroundings.

Brief history of Jökulsárlón

Jökulsárlón is a relatively young natural wonder. It began forming in the 1930s as Breiðamerkurjökull glacier retreated, leaving behind a deep basin that gradually filled with meltwater. Today, it covers around 18–25 km² and is Iceland’s deepest lake at nearly 300 meters. The lagoon continues to grow as the glacier recedes, a visible reminder of climate change. In 2019, the area became part of Vatnajökull National Park, a UNESCO World Heritage Site.

Tips for visiting Jökulsárlón

• Arrive early morning or late evening to avoid peak crowds.
• Dress in warm and layered clothing as the wind off the glacier can be very cold, even in summer.
• Book ice cave and boat tours in advance, especially in high season.
• Use caution near the water’s edge; the icebergs can shift suddenly.
• Stay for sunset or after dark in winter for a chance to see the Northern Lights.
