Pro Tips
- 1.Arrive before 10 AM on summer weekends to snag parking and a prime picnic shelter spot,the lot fills up quickly on hot days
- 2.Bring water shoes for the kids as the beach has some rocky areas, plus shade equipment since tree cover near the beach is limited
- 3.The Sunset Beach area (north side) tends to be less crowded than the main beach and has a newer playground
- 4.Pack a wagon or cart to haul your gear from the parking lot to the beach,it's a bit of a walk with little ones
- 5.Download your Discover Pass ahead of time or purchase at the entrance; it's required for parking and helps avoid delays
Best Time to Visit
Weekday mornings from late June through August offer the best weather with smaller crowds. Aim for 9-11 AM before peak heat and congestion. Spring and fall are lovely for hiking and picnicking without the summer beach crowds, though swimming will be chilly.
What to Know
Requires a Washington State Discover Pass ($10 daily or $30 annual) for parking. Restrooms, changing facilities, and outdoor showers are available. Limited food concessions operate in summer, so bring your own snacks and meals for the best experience.
Seasonal Notes
Peak season is June through September when swimming is most comfortable and lifeguards are on duty. The park remains open year-round with reduced hours in winter, perfect for off-season walks and wildlife watching. Some facilities may close during winter months.
