There may be some usable metro or commuter-rail support near 성남시, but it is not the whole story. In this type of region, KTX stations, conventional rail stations, and express-bus terminals are often the real movement anchors.

Regional buses in 경기도 are important for local coverage, but travelers often feel the lower frequency or earlier last departures compared with the largest metro areas. For day trips, it is wise to calculate not only how to go in by bus but also how to come back out if service becomes thin.

Taxis in 성남시 are useful when the final destination still sits far from the station or terminal, or when transfers feel cumbersome. They are especially practical late at night, in rain, or on luggage-heavy days.

성남시 is usually walkable inside one neighborhood or attraction cluster, but not necessarily across the whole district. A practical pattern is to walk one cluster thoroughly and then switch back to transit.
