Sometimes I find these, are they frogs or toads?
Length of about 3 inches / 7.5 cm (not that I've ever measured one, though).

Looking at the feet, looks more like a toad since it is not webbed, body shape is stubbier, and the color of the skin is darker.

It's a toad.
Good friend in garden.

I'd guess a Toad also; a good critter to have in the garden because they eat insects.
For a more exact ID of which Toad it might be you can google for Toads of your country.

Where in Europe is this toad?
You can encourage toads to breed right in your own yard if you keep a small body of water. I used a simple stainless steel pan from a restaurant, kept the water fresh and in the spring the toads mated and produced eggs for a new generation of toads. Toads are a good friend in the garden and eat tons of insects.

frogs; smooth skin,stay mostly in water
toads; thicker bumpy (`warts`) skin, mostly on land

Quite the consensus, thank you everyone!

There actually is a body of water, a small lake, not 100 yards / meters away, that's where they may be coming from.

Following plantladylin's advice, I looked for a list of species that can be found here and it seems to be... the common toad There were only three and the other two look distinctly different than these, so this must be it.

I miss frogs and toads..wish we have them here..you are lucky to have one there!

I have them. No waterpond or anything. They go dormant when its to dry. They just need a damp place to live. They live in the thick laver of leaves under my tree. If you have evergreen shrubs, they'll live there too. When cool at nite, they'll come out and feed. Even in summertime !!! Dogs and cats dont bother them. When threatened, they secreat a stinky substance that is nasty to animals.

We used to have chorus croaking here about 4 to 5 years ago during Spring time, then when the drought worsened it did not comeback.
