El empeoramiento de la situación sanitaria ocasionada por la pandemia ha provocado que la Junta de Castilla y León haya adoptado el acuerdo de suspensión, a partir del sábado 23 de enero de los servicios presenciales en casas del parque, centros temáticos y aulas del río de espacios naturales protegidos de la región. En consonancia con ello, y de acuerdo al Convenio de encomienda de gestión existente entre la Junta de Castilla y León y el Organismo Autónomo Parques Nacionales, el Centro de Visitantes Valle de Valsaín-Boca del Asno queda cerrado al público hasta nuevo aviso. Se continuará con la atención telefónica y a través de correo electrónico como habitualmente.
