Short and (more or less) easy cache in the Viennese recreation area "Prater-Auen". You will visit some interesting objects along your route.
The area was a former hunting ground of the emperors. Details about the area can be found at:
http://www.lusthaus-wien.at/
You can reach the cache area by public transport. Take the U3 direction "Simmering" till "Schlachthausgasse", and there you take the bus 77A direction "Gärtnerstraße" till "Lusthaus". The starting point is very close to this station. Those coming by car, can park there.
The trail is most of it`s length a gravel walk. Only for the last meters to the cache you have to leave the path. No special equipment is needed, a citymap could be useful and a mosquito repellent is recommended during summer season.
Length to the cache: 1 km, no difference in height.
The above difficulty and terrain rating was done with the program from geocaching.com. To be internationally comparable I`m using this result. (See the discussion in the forum also.) My personal opinion is a rating of 2 stars for difficulty and 2.5 stars for terrain.
Stage 1: The Island of Joy
N1 = 48° 11.556´
E1 = 016° 26.338´
Go to the island of joy and count the chestnut trees around the building. The result is A.
Stage 2: Green Mary
N2 = 48° 11.x2´ where x2 = 671
E2 = 016° 26.y2´ where y2 = 590
Look for a memorial place (a small brick wall) for persons who died from the same disease. (Maybe you want to light a candle there). Count all the letters E and I on the tablet. The result is B.
Stage 3: The Founder
N3 = 48° 11.x3´ where x3 = x2 - B * 3 - 4
E3 = 016° 26.y3´ where y3 = y2 + A * 7 + B * 7 + 1
Look for the memorial area for the founder of Green Mary. There are single stones and statues. Count all single stones as C and all statues as D.
Stage 4: The Cache
N4 = 48° 11.x4´ where x4 = x3 - B * C + 4
E4 = 016° 26.y4´ where y4 = y3 + A * B * D - 2
Good Luck!
