Take a day trip to San Diego.
My husband and I originally wanted to spend a weekend there. After doing some research about places (Cabrillo State Monument and the Torrey Pines Nature Reserve) that we wanted to visit, we eventually realized (too late) that it just wouldn't have been feasible since our dog would have had to stay in the car. Though it was already the end of September, it still would have been too hot and we could not have left her at the hotel since the check in time was later on in the day. So we left the dog at home and cancelled our hotel reservation. After a late start to the morning, we drove down and hit our main stop: Cabrillo National Monument. The monument was built to commemorate Juan Cabrillo, the first (recorded) European to land on the West Coast of the present-day United States.
It was a gorgeous day as you can see in the photos below.
