As of right now, the forecast for Saturday is for clear skies with a high of 70 and a low of 49. OPI however suggests: "For your comfort, you may want to come prepared for wind, rain, fog, or sunny weather. Layering your clothing can be an effective strategy for the variable climate."
Items to bring along:
    TOWELS: OPI does not provide bath towels or wash cloths.
    TOILETRIES: Bar of soap, shampoo, toothpaste, medications. If you anticipate needing basics such as aspirin, ibuprofen, or stomach remedies, please bring those as well. 
    FOOT GEAR: something to hike in/swim in/canoe in if you anticipate partaking in these types of activities.
    SWIMSUIT: for lounging in hot springs on Sunday or if you want to join the Polar Bear club in Lake Crescent
    SHOWER SHOES:  If desired.
    RAIN GEAR:  Hopefully you won't need this, but a rain jacket can be useful as a windbreaker too - it could get windy on the lake if you participate in the canoeing.
