If you are on the road to Granada, you need to stop at the mirador de Catarina. When you enter the city, there are many flower shops and that part of town is really beautiful.
You can park for a few Cordobas neat the viewpoint. The view is splendid: Deep blue lake, in a crater and you are on top of it. You can see the whole lake from it.
This is a very touristy place, with lots vendors and musicians, but it is pleasant anyway. Horse rides are available there to go down the lake if you wish, (you could walk down too). A couple of small hotels surround the lake with forest. We ate in a restaurant overlooking the lake. Real good view, but it's windy too! Next stop, Granada.
I'm mainly a nature's lover with a net preference for snakes, lizards, crocodiles and frogs. But i try to always incorporate landscapes, architecture, people and other stuff related to the country where i go, so that it could please to a larger audience!... full info
