This chapter discusses the walking accessibility to primary healthcare by the olders in Lisbon Metropolitan Area (LMA), Portugal, and its contribution for age-friendly environments as a factor of inequity. Constrains emerged from the collation of the supply approach, represented by service catchment areas based on walking distance time, and the demand approach, through a survey. The location and density of primary health network are a major factor, as it is related to distinct land use patterns within the LMA. The settlement structure influences the potential walkability to primary healthcare. The discrepancy between the potential walking accessibility and the real options is notorious, as olders` choices are diversified in terms of transportation modes and destinations, but mostly keeping relatively short time distances. This phenomenon is also influenced by factors such as personal preference, difficulty to walk, negative perceptions about the surroundings, and insufficient care support. This debate is already an effective concern of local authorities with spatial planning, social and health competences, insofar as solutions in terms of service flexibility and new travel solutions adapted to the specific needs of the olders are a growing reality in the LMA, promoting more age-friendly, health, and inclusive environments, and hence an equitable metropolis.
