Xplore Anza-Borrego State Park Hi. My name is Omar Sierra and ever since I can remember, I have loved to explore the wildlife. I have traversed nearly every square mile of my hometown and since I moved to San Diego, I have been amazed with the most beautiful sceneries that I will love to share with you. Exploring for me is not a break from regular life - it is regular life. As your private expedition lead, I’ll share with you my love of explore, and ensure you have a nature-filled adventure.
