they escape to their "dachas".
But what's a "dacha"? Spotlight on
Russia finds out more ...
to
Many Russian people have a
plot 2 of land out in the country
called a "dacha". They often have
a small house there where they
can relax or grow fruit and
vegetables in the garden.
Dachas are usually a few
kilometres outside the city. So
on Friday evening and Saturday
morning thousands of cars,
buses and local trains carry
millions of people to their
dachas outside
the city.
People take bags, backpacks
and small carts with what
they need for a relaxing
weekend at the dacha. You
can often see cats and dogs
in the cars as people usually
take their pets with them.
People spend their
weekends at their dachas during
the spring summer
and autumn.
During the spring people clear
the garden. Many people plant
vegetables such as cucumbers,
tomatoes, onions and potatoes
while others prefer to grow
flowers. In the summer, families
swim and fish in nearby lakes and
rivers. They also pick* fruit and
berries which they use to make
jam. Autumn is
is the most
beautiful season at the dacha. All
of the trees, grass and plants are
green, red and yellow and there
are a lot of colourful flowers.
During the long, cold Russian
winters people can't wait to
return to their dachas. There
they can relax and get away from
the busy city life.
