During the warmer months,the holiday center hosts adventure nights
out. Guests can sleep in their own portaledges (吊帐), hanging several
meters above the groud .
A portaledge is a hanging tent system
that is generally used by rock climbers on more than one day climbs. At
Waldseilgarten, the tents are hung from thick branches of large
free-standing trees ,where guests can only ascend or descend with the
help of ropes.
Guests that look for more air and an extreme
camping experience can choose to sleep on an overhanging platform . It
lies among huge cliffs between 1,000 and 2,000 meters high . However, if
that’s just a little too extreme for you, the holiday center will also
offer some easier sleeping choices .You can sleep on cliff platforms
between 100 and 300 meters high ,or on tree platforms hanging between
trees . They are easy ways to go down to the ground at any time.
All
guests that join in an adventure night out will receive
rope(绳索)climbing training before spending a night in nature .
Waldesilgarten seems to offer a camping experience you will surly
remember .However, that experience doesn’t come cheap.
A night
sleeping in the trees in portaledge will cost $336 per person , while
the cliff platforms will cost you $1,199. The cheapest choice is the
tree platform , whose price is $168 per person per night.
