Travelling to LA in July. My husband and I are both experienced horse and mountain bike riders who would like to take advantage of our teenagers being in Disneyland and find some good horse riding and mountain biking nearby. We are staying at Newport beach. Any suggestions?. Have seen a few horse riding places online with mixed reviews, and didn't appear to cater for experienced riders. Haven't yet investigated the mountain biking but would be looking for a centre that takes out small groups with a guide.
