Frequently Asked Questions
Why is Birch Bay warm?
The bay is shallow and broad, so summer sun warms the water more than deeper Puget Sound inlets, making it popular for swimming.
Seasonal Note
Trail conditions, beach staffing, boat rentals and road access change with the season. Confirm current hours and closures with the managing agency before you travel, especially in winter and early spring.
