Through a qualitative methodological design in which the hermeneutic and phenomenological methods were used, and the semi-structured in-depth interview and focus group techniques, this work focuses on the question: ¿Why do the rights of access to information, participation and justice in environmental matters in the Raizal ethnic community of the archipelago department of San Andrés, Providencia and Santa Catalina, constitute expressions of biocultural rights in the Colombian legal system? The resolution of the problem initially allows to disclose in depth the methodological experience used from which the findings were obtained. The first conceptualizes the rights of access in environmental matters as dimensions of the fundamental rights to information, participation and justice, giving rise to the question ¿What are the rights of access in environmental matters as dimensions of the fundamental rights to information, participation and justice? and the second, establishes the significance of the raizality as a differential ethnic condition from which the rights of access in environmental matters are configured as expressions of biocultural rights, an objective that is reflected in the question ¿What meanings does the raizality of the community of the archipelago department of San Andrés, Providencia and Santa Catalina have that contribute to the configuration of the rights of access in environmental matters as biocultural rights?
