    There are, indeed, horses on this hill. Connector path between Mill Valley and Corte Madera, easier than Camino alto. The alto tunnel is still closed, learn more here: openaltotunnel.org

    Road cycling

    Horse Hill (Alto Hill) bike trail segment hugs Hwy 101's west side to cross this steep ridge between Mill Valley and Corte Madera, the slightly less tedious option instead of double the elevation difference on Camino Alto. It was freshly repaved in 12/2016. The Alto Tunnel (a rail tunnel closed in the 1970s) conversion that would connect the Mill Valley bike trails to the south and north is still not planned or financed. openaltotunnel.org/faq2
