Attractions and Tips

San Diego's Zoo is one of the world’s largest zoos and alone is reason enough to visit the area. The zoo is home to one of world's few giant panda exhibits and houses thousands of animals; it also includes the Safari Park, which allows some up close and personal experiences with exotic animals.

San Diego is home to an impressive Automotive Museum and an Air and Space Museum, and you can find a few whale watching tours on the coast. The city's Belmont Park is an excellent stop for carnival ride enthusiasts, and SeaWorld San Diego is a family favorite.

San Diego’s temperature rarely dips below 50 degrees, even during the coldest winter nights, and highs stay between 60 and 80 degrees all year round, making it a comfortable, while dry, place to stay. Late summer and early autumn can sometimes reach 90 degrees.
