First, never try running anything through trees - flex too much, and if wires don't break, sheath will rub through on bark eventually, and cause problems. Could put up poles, but gotta have a stringer to hold up the cable because over that distance copper will stretch and break over time. And running airial cables most generally require a permit ahead of time anyway. Can't bury because of stone retaining walls? How deep are they? Can't get underneath them? And if can and do, at least put a conduit sleave underneath them for potential settling of the walls. Are they part of a foundation? If so, come up out of the ground and stub into your bldgs (coop and source) with 90 degree LB's (resemble elbow, but have a cap for access). Conduit stub from LB into the ground to your local code depth, then can run proper direct buial from point A to point B. Make sure have good grounding and ckt brkrs at both ends of the cable - lightning locates and loves shallow cable. And one GFI per ckt as your first recept - trying to add multiple GFIs on a same ckt will cancel each other out, and will always be popping off the ckt brkr. Isn't a hard job to do, but since you're asking, you may want to trench and have a licensed electrician handle for you. Oh yeah, if you bury, dig a straight trench, and mark both ends, that way you can eyeball the path in the future before digging through your cable. People often dig through cables because kind've remember where they put them, sort've, but not really. Happens everyday. And one last thing: KNOW WHERE EXISTING SERVICE IS BURIED BEFORE YOU DIG. May want to have existing located before you dig so don't hit gas, electric, water, telephone, cable TV, etc.
