Sunnydale is a medium-sized neighborhood on the southeast side of San Francisco. It is bordered by the Gleneagles GC McLaren Park on the north and west sides, by Bayshore Heights on the south, and by Visitacion Valley on the east. About two-thirds of the neighborhood is made up of newer housing with landscaping and the rest of the neighborhood is made up of small single-family homes.
The few restaurants and businesses in the neighborhood tend to be on Geneva Avenue. The SF Dog Parlour is not far east and will provide a great bath for your dog. For training, you will have a slightly longer trip north to Ace Dog Sports where you can get advanced training and mental stimulation for your pup.
There are miles of wilderness for you and your dog to explore at the John McLaren Park, but if you want more, the San Bruno Mountain State and County Park has miles of open country wilderness.
About a third of Sunnydale is made up of single-family homes that are spaced flush together and have similar but interestingly different designs. These homes open directly onto the sidewalk and there is no grass between home and sidewalk or sidewalk and road. There are, however, some mature trees and the views of the mountains are lovely. This is a slightly close but not unpleasant walk for you and your pup. Most of the trees in this area are not very tall, so it can be a hot walk on the hottest San Francisco days. It isn't hard to find a diverse walking experience in Sunnydale.
If you head north, you will find the John McLaren Park with its gorgeous natural paths and mature tree cover. There is a lovely reservoir in this park that is great on hot San Francisco days. If you go south, the San Bruno Mountain State and County Park offers nearly unlimited exploration over diverse, mountainous terrain.
Sunnydale is fortunate in being sandwiched between two beautiful parks. You can choose between a manicured park experience or wilderness exploration every time you take your dog for a walk. John McLaren Park has lovely trails through tree cover that makes for a nice shady walk on hot San Francisco days. The McLaren Upper Reservoir provides somewhere for you to get your feet wet and cool down as well while the gently rolling hills and well-maintained trails of this park offer pleasant but not overly exciting rambles.
The San Bruno Mountain State and County Park has miles of foothills and rocky terrain. The rocky trails that run through the sand and undergrowth of this park will challenge you and your dog and provide extensive mental and physical stimulation. If you are up for a serious hike, you can follow the top ridge of the mountainous park all the way to the coast.
