You can reach san juan hill from every direction... some routes are shorter than others. I've came here from the chino hills area - from the casino ridge staging area - Yorba Linda ... all the slopes are steep at first, then rolling hills. Bikes joggers and walkers and runners are all welcomed. Open paths, all routes are clearly marked , and the difficulty level moderate to hard- please be ready to hike steep hills and deal with loose gravel and soil. Opportunities for photography abound. A strong 3.75 to 4.25 score for accessibility fun level and upkeep. read more
