Sometimes I miss having the water nearby more than other times. It's usually during the spring and summer that I most wish I could just drive a few minutes and be able to enjoy an evening on the pier, walking around feeling that cool ocean breeze, and maybe even picking up an ice cream to finish the night.
White Rock, although not very large, is a great place to spend an evening. If you can find your way through the (beautiful) neighborhoods and down the hills to the pebbly beach, you'll be welcomed with a view of the ocean with mountains in the background.
If you have extra time while visiting the Vancouver area, it's a nice break from the big city and a fun place to walk around and relax.
