Walking through lava fields, is not the same as skipping through fields of
pansies and butterflies. The closer you get to the goal, the higher the
temperature and the humidity. The terrain is uneven and rough, and in many
places it may be fragile and not yet completely solidified. The temperature
during the day often climbs into the high 90s. The humidity combined with the
heat of the lava creates a sauna-like environment. People on certain
medications (check with your doctor) are at a higher risk of heat stroke, which
can be fatal.
If you come across and area that is roped off or blocked with a sign, do not
disregard the warning. To do so could result in you stepping onto the ceiling
of a collapsible lava tube.

You will most certainly be warned to stay at least ¼ of a mile inland. The
new land that is formed where the lava meets the ocean is called a bench, and
is unstable. There have been several incidents of people disregarding the
warnings and entering the bench area; they died when the bench area collapsed
into the ocean.
Life threatening fumes containing volcanic blasts and hydrochloric acid are
created when lava enters the ocean. Avoid these fume clouds, especially if you
have asthma or any other breathing problems.
