If we would like to talk about danger in Dilijan, then there is no more important thing to talk about rather than health. I stayed in a hotel named "Dili Villa" which is a nice place, but no hygine care is taken. The place is dirty, especially the toilets, so I had worries to eat there. Pets are alowed inside, and they have dogs living there. I saw the hair of a dog in my first soup !! I hope more hygine care will be taken especially in such public places.
Watch your steps - the terrain is uneven and if you are not careful it's easy to fall and hurt yourself. If you do - second warning - avoid the hospitals of Dilijian. After some evident x-rays they told me i had a micro-fracture in my arm, made a tentative casting and sent me off (no painkillerws or nothing).
After another hospital visit in Yerevan it turned out that the fracture was double and dislocated (and needed to be reduced). The casting was totally wrong, too...
