A short way further up the same hill is a cable car (look for the signs to 'lanovka') linking the hill top with the Železná studnička valley.  At the bottom of the valley (about 4 kilometres' walk; or a few minutes by bus) is one of Bratislava's best children's playgrounds. A small railway station and a bus stop serve the area (go under the red bridge), both with connections back to the city.

Getting there:

There are many possible starting points for a short family trip, a walk, or an all-day hike from the city.

Probably the quickest way into the hills is to take the number 203 trolleybus from Hodžovo námestie (in front of the Presidential Palace), in the direction of Koliba.  Get off at the last stop and walk up the hill, where you will quickly enter the forest.  The forest trails emerge at the hill-top clearing described above. Longer trails into the hills start from here.

Alternatively, take a train from the main railway station (hlavná stanica) to Bratislava-Železná studienka station, from where a trail (and a nearby road) leads up the tree-lined valley.  Along the way are the children's playground mentioned above, and several lakes.  A cable car connects the head of the valley to the hill-top at Koliba.
