how far from potlach state park is it to seatle?

About 2.5hr depending on traffic. Approx the same as taking the Bremerton/Seattle ferry

2-3 hrs depending on traffic or if you take Bremerton Ferry

Depends on traffic. 2-4 hours depending on what time of day you leave.

2.5 hrs it's going down I -5 past the Olypia State Capitol then turn off going to Shelton for about 45 min it will be on the right had side of the road you will enjoy the place.

It take me about 1hr15 min from Bremerton to potlatch. Add another hr on the ferry

If you take the Bremerton Seattle ferry it's maybe a 2 hour drive or about 50 miles
