AllTrails is a great resource and phone application that contains tons of hikes. One of the features of the Pro version is it allows you to download maps for use when you're offline, which is literally a life saver to help you from getting lost. Our friends over there have hooked us up with an exclusive list of the top 52 trails in all 50 states, download it here! No more researching for hours to find a good trail with this list and their app containing all the information you need to get going quickly. Just be sure to download the maps while you still have cell phone reception.
If you are local to Orange County, CA you can find all the maps for the trails & parks here:
Jerry Schad's book, the 101 Hikes in Southern California, is a great guide book. Click here to order your copy through our REI link.
If you are more advanced, comfortable with off-route navigation, and in San Diego, be sure to check out one of theses 100 peaks.
There are always new websites popping up online to find great places to hike. If you think we need to add one to the list, please contact us.
