Iceland is known for its famous Blue Lagoon geothermal baths, but to save money and beat the crowds, visit this hot spring tucked in a forest instead.

Emergency services also evacuated the nearby Blue Lagoon luxury spa hours ahead of the eruption. A volcano has erupted near Iceland's capital, spewing lava and smoke, and triggering the evacuation of tourists and residents.

The magma flow began at about 6.30am local time accompanied by an intense earthquake storm similar to previous eruptions, Iceland's Met Office says.
