Venice is a neighborhood adjacent to the beach, and the canal district is just a couple of blocks east of the ocean. According to Wikipedia, "The district is noteworthy for its man-made canals built in 1905 by developer Abbot Kinney as part of his 'Venice in America' plan." It says that they fell into disrepair for around 40 years but were renovated in 1992. Pretty nice real estate now! You can walk on pathways along the canals, and there are lots of bridges to cross over and easily get around the neighborhood.
A lot of the houses have very nice landscaping. Here's part of a yard with a cactus theme:
