Point Loma

Point Loma extends south past downtown San Diego heading towards Mexico.  On your drive here, you'll pass Fort Rosecrans National Cemetery, which is an active cemetery contain the graves of over 88,000 American veterans.  This area does give great views of San Diego harbor, but since this is an active cemetery, please be respectful when visiting.

After driving past the cemetery, you'll enter the Point Loma area National Monument area, which will charge you a $5 parking fee.  Once inside, you'll be able to walk around the Cabrillo Monument area for stunning views of downtown San Diego.  Nowhere else will you be able to get views of the city quite like this.  In addition, the Cabrillo Monument itself is quite impressive and is worth the visit.

A short walk from here is the Old Point Loma Lighthouse, which you may enter.  This is quite a small lighthouse, which is one of the reasons it was de-commissioned, so it's an easy climb to the top for any visitors.  You'll get a much better view from outside though of San Diego Harbor.
