Granada:
hire a bicycle.... so nice to bike around
go around with 2 or 3 people with a taxi to canapy, vulcano, little villages, masaya...... so nice, you can stop where you want and see such a nice things! so much nicer than a tour!!!

Ometepe:
a bike is again really nice option!
climb the maderas! swim at the top
go to ojo del agua, just so nice!
stay in between the 2 vulcanos, really great!i loved to stay at El Encato

Leon
viavia is a nice place to stay
quetzaltrekkers: telica vulcano tour is just a nice vulcano trip! Loved it!
it's possible to go from Leon to El Salvador or Guatemala... just see the travelinfo at ViaVia cafe!
Dangers: we only came across robbery stories around masaya.....
don't go in taxi's with other people
don't hitchhike or go with people in a car
We came across some bad experiences from people who did the things above.... a woman lead gang who will take all your valuables and force you to take money out of the bank.
For the rest, Nica is really really safe!!!!
