From a July 24, 2020, Snohomish County press release.
Due to an overwhelming number of visitors this summer, our parks and facilities have become stretched beyond capacity, which has impeding safe social distancing.
Rangers will therefore be turning vehicles and pedestrians away once our parks reach capacity.
Please keep in mind, picnic shelter reservations do not guarantee parking so we strongly encourage carpooling and arriving no later than 11:00 am.
Visitors with camping reservations will be granted access.
