Eltsu is a small wall of about 3m high. It is located in Eläintarha city park, between Olympic stadium and Linnanmäki amusement park.
The small face is home to 6 quite nice boulder problems. The face is in the shade all day, so it might be a good choice for warmer days.
Eltsu has super easy access. You can walk here from anywhere in the city.
There is some moss above the cliff so it might be damp some time after heavy rain.
