Molde is located on a fairly narrow strip of land, between the sea and the mountains (or rather, hills), next to the Moldefjord. The hilly area behind the city is known as Moldemarka, and while it doesn't really have any spectacular mountains, the highest one being something like 650 meters, it's a very nice area for shorter trips. A fairly extensive network of gravel paths makes the area easily accessible by foot and bike, and even by wheelchair, at least with a motor or someone to push.
There are several lakes and ponds, and most of the lakes have fish in them, although you probably won't get anything very huge. Three of the lakes provide drinking water for Molde and the surrounding area, but in the other lakes, swimming is allowed if you are so inclined.
Unfortunately, most of my images are temporarily unavailable for geographical reasons, but here are some earlier articles with pictures taken in Moldemarka:
