At PARK21, sports are high on the agenda. Sports facilities can provide both a meeting place for national and international teams and ample opportunities for just relaxing actively outdoors. Along the edge of the park, space is designated for a large-scale, multifunctional sports complex with facilities for top professional sporting events.

A 12-hectare baseball complex was recently opened for the local Hoofddorp Pioniers team, which is suitable for international tournaments and can hold 25,000 visitors. There are also other sites of up to 15 hectares available for sports facilities elsewhere in the park. One possible development envisioned is an equestrian center, with a race course, stables, training facilities, a guesthouse, a shop and a blacksmith.
