Lake Miramar Scripps Ranch, CA This lake isn’t actually a lake at all, but a man-made reservoir, surrounded by a 5.2 mile paved loop. Lake Miramar is located on top of a tall hill, just east of Mira Mesa. This elevated location means beautiful views of San Diego County and the perfect spot for a sunset skate. This trail can get hot on a sunny day, but luckily, there’s plenty of shade to keep you cool. Port-a-potties and water fountains are spotted around the loop for public use.
