Heinabergslón

• Icebergs and ice fragments along gravel shores, with the glacier looming at the head of the lagoon.
• Occasional wildlife: travelers have reported curious seals in the water and, at times, reindeer in the broader area. Expect birdlife typical of glacial lagoons—give nesting birds space.
• Broad, photogenic vistas where ice, water, and moraine meet.

Several marked routes start near the lagoon parking. Wayfinding can be sparse and yellow-tipped markers don’t cover every section, so offline GPS helps. A smart approach is an out-and-back along the best viewpoints toward the glacier, skipping any long, less-interesting road-walk sections. There’s also a short interpretive trail by the parking area with panels about vanishing glaciers—worth a few minutes before you wander further.

This lagoon is a favorite for guided kayaking in small groups—typically half-day outings with 1.5–2 hours on the water, weaving among ice and soaking up the solitude. If the road or river conditions make you hesitant to explore on your own, guided options are a stress-free way to experience the lagoon safely and up close.

Weather changes fast, rivers rise quickly, and winds can be fierce. Check the forecast and road conditions before you go, and build in extra time. Stay off icebergs and glacier ice—calving can send waves and debris shoreward. Follow park guidance: keep to marked routes, drive only on designated roads, don’t disturb wildlife, keep dogs leashed, pack out all waste, and note that overnighting is restricted to designated camping areas. For emergencies in Iceland, dial 112.
