The only off-leash hiking area in the city, Runyon Canyon is the best place to let your dog run free and enjoy sprawling views of the Hollywood Hills. With 90 acres to roam, both you and Prince will get a good workout walk or run. Of course, this see-and-be-seen slice of nature is also known as a great celebrity-spotting sight (we frequently see Jason Bateman jogging up the mountain). We like the short hike to Indian Rock, the highest point in the canyon; there's a good resting spot, with flat areas to play a game of fetch or Frisbee and 360-degree views of the city. On a clear day, you can even catch a glimpse of the ocean. Bring a bone and sit down for a picnic with your loyal hound. The winding trails on the way back down are perfect for doggy socializing. And who knows? Dogs are known to be good matchmakers — so pay attention when yours runs up for a sniff of someone new.
