Summer ride along the beach? Why, yes, of course it's great.

This pedestrian/bicycle bridge over WA-509 is a bit of a relic, but an interesting attempt at a cost-effective solution. Be VERY careful cycling across (a safer bet is walking the bike down/up the ramp)... Good adrenalin-producing ride.

The ferry can take you from here to Southworth and Vashon Island. Crossing time is usually about 45 minutes. There is a walkway on the left side of the pier from which you get a nice view over the Puget Sound.

It's interesting name comes from the language of the local people who lived there first. This park helps protect the land where the water meets the shore. This habitat is very important for many animals and plants. Birds come here to find food and rest. Small creatures live in the mud and sand. Even fish use this area when they are young. The plants that grow here help keep the water clean and give shelter to animals.

Three Tree Point in Burien is a quiet, scenic neighborhood tucked along Puget Sound. Riding along SW 172nd Street offers a particularly beautiful stretch hugged by waterfront homes with sweeping views of the sound. The road follows the shoreline closely, making for a peaceful, low-traffic ride with glimpses of the mountains across the water on clear days.
