How do I fly to Borrego Valley (L08) if it's inside a CA state park?
Having never flown into this airport before, I would study the sectionals and charts very carefully. The state park is one concern. There are specific notes on the sectional requesting aircraft to stay above 2000 feet. There are also restricted areas, military training areas, laser illumination areas, etc. all around the airport. Not to mention the rising terrain and obstacles as high as 7100 feet around an airport with a 522-foot field elevation and a 10,000-foot Minimum Sector Altitude. Then, the airport having to have a specific obstacle departure procedure is a big red flag for me. 

If it were me flying into this airport, I would request flight following to the RNAV (GPS) RWY 26 IAP all the way in to the traffic pattern. Then, I would land straight in or circle to runway 8. The minimums are probably a full 1200 feet above the field elevation for a reason. Remember to circle South of the airfield (right traffic pattern for runway 8). And, do not overfly the area Northwest of the field nor the elementary school 1 nautical mile West of the field. This is from a quick glance of the charts and chart supplement.
