This is a fun but challenging loop up and down the Santa Barbara front country.

Park at the San Ysidro lower trail head, then transit to the bottom of Romero Canyon. Up Romero to Camino Cielo, then across to San Ysidro and down.

The SanYsidro Trail starts out smooth and then gets a little loose and finally very rocky but its a fun trail to do.

In great condition now that SBMTV cleared a lot of the brush at the top last weekend. The middle section still needs some work as they weren't able to get it all.... still, insanely fun!
