Seeing a volcano erupt(喷发) is a wonderful experience, and you can really feel the beat
by climbing to the summit(山顶) of Pacaya for a close-up view. There are guided tours
every day up thishighly active volcano from Antigua. Giving travelers a chance to see
Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua,a beautiful city with many colorful houses along its
old streets that are turned into art-works during its Holy Week festival. No matter when
you come to Antigua, you won't miss the Pacaya-tour companies.
But climbing Pacaya is no easy job : it is 2,560metreshigh, and reaching the summit
takes two to three hours of seemingly one-step-forward and two-step-back movements.
As you climb, you hear the dull sounds of eruptions high above. Steaming, hot remains
from recent eruptions begin to line the path as you near the active summit :the
McKenney Cone (火山锥). Just as though you were going to walk over to the edge of the
cone , the road turns to the left and up to the relative safety of the old,inactive summit.
Many tours are timed so that you arrive at the cone of the volcano in plenty of time
for sunset and the full contrast between the erupting red lava(熔岩)and the daikening sky.
On a good day the view from the summit is extremely exciting. The active mouth boils ,
sending red lava over its sides, and once in a while shoots hot streams up t0 100 metres
into the air. There is a strong bad smell in the air even if you take care to be upwind of the
cone. As evening turns deeper into the night, the burning lava quietly falls down the side
of the volcano. For you , too , it is time to get down.
