Having fun in the fall leaves – Marian Bear Park San Diego Fall Family Portraits. This location is a great alternative to Old Poway Railroad Park for family portraits. Old Poway Park gets very crowded in the fall, and can be challenging to work around other families and visitors. Marian Bear Park has beautiful leaves, trees, fallen logs and stumps, and tall wispy grasses in greens, oranges and yellow colors. Another popular location in the fall for family pictures is Rancho Bernardo Winery, but as of 2012 they charge a $150 fee to use their property for photo shoots.
