Corporate Apartments. Where Convenience Meets Scenic Beauty! As you look out onto the majestic beauty of Mount Diablo, it's easy to forget that you're only minutes from San Francisco and San Jose. Here, you can have the best of both worlds. Go horseback riding on historic Iron Horse Regional Trail just up the road, then meet friends for dinner in the city. Spend an afternoon mountain biking and take in an evening concert on the Bay. Enjoy life the way you want at Ironhorse Trail!
