Swimming in Iceberg Lake is not recommended for safety reasons. The water is extremely cold, being glacier-fed, and poses a risk of hypothermia. The lake is best enjoyed from its shores, admiring the floating icebergs and stunning scenery.

The presence of icebergs well into the summer is due to the lake's unique characteristics: its cold, glacier-fed waters, its north-facing cirque position, and the significant shade provided by towering peaks like Mount Wilbur and Iceberg Peak. These factors create a microclimate that preserves the ice longer.
