Tips & Recommendations
- 1Reserve campsites well in advance for popular swimming destinations, especially state parks like Deception Pass and Steamboat Rock which fill quickly for summer weekends.
- 2Bring water shoes or sandals for rocky lake bottoms common at mountain destinations like Bonaparte Lake and West Sullivan, where submerged rocks and uneven terrain can make barefoot entry challenging.
- 3Pack layers and warm clothing even for summer trips, as Washington's mountain lakes maintain cool water temperatures and evenings can be chilly regardless of daytime heat.
- 4A wetsuit or rash guard can extend swimming comfort, particularly at higher-elevation sites or for children who want to spend extended time in the water.
