Anza-Borrego Desert State Park is a must-see for wide-open vistas, slot canyons and springtime wildflower displays that are reachable by paved and graded roads from San Diego Country Estates. Palomar Observatory and its surrounding mountain roads offer a cooler, forested contrast and memorable stargazing pullouts accessible by car. Take Highway 79 for a scenic, well-maintained route that connects valleys and higher country—its grades and shoulders make it suitable for larger vehicles and offer several convenient turnouts. If you’re traveling in a campervan, these drives provide a compact, nimble way to enjoy long-distance views without sacrificing gear or sleeping comfort.
