Frequently Asked Questions
What is the Olympic Rain Shadow?
The Olympic Rain Shadow is a meteorological phenomenon where the Olympic Mountains block moisture-laden Pacific storms, creating a significantly drier climate on the northeastern side of the peninsula. Sequim receives about 16 inches of annual rainfall — comparable to Los Angeles — while areas just 30 miles west on the Olympic Peninsula receive over 100 inches.
Is the park noisy from Highway 101?
Yes — the park is adjacent to Highway 101, and some campers report road noise. For quieter sites, request locations farther from the highway when making reservations. The park tunnel provides safe pedestrian access between the two sides of the park.
