Estuve varios días esquiando en Cerro Castor. Sus pistas son excelentes y la infraestructura de sus medios de elevación, eficiente. Los paradores distribuidos por toda la montaña son comparables, y en casos mejores, a los de los centros de ski de Aspen en USA. Los precios son razonables y el personal del Cerro está siempre atento a las necesidades de los visitantes. Amplia variedad de oferta de equipos en los rentals y un espacio con lockers calefaccionados para dejar los equipo, recién inaugurado, propio de un centro de primer nivel. La escuela de ski tiene precios razonables, lo que me permitió acceder a tomar clases todos los días. Hacía por lo menos cinco años que no visitaba Castor. Lo encontré muy cambiado,y todo para mejor. Se ve claramente el nivel de inversiones realizadas.
