If the fog is making you sing the blues, it's time to turn the tide. Add a skip to your step and a splish to your splash with any of these refreshing summer adventures.

Clarks Automatic Refresher: Break up the trip to Tahoe with a cool-down along the way. Clarks Pool swimming hole, just off I-80 near Auburn, is an emerald oasis set under the tallest bridge in California.

Splash Camp: Pitch your tent under the redwoods and next to swimming-hole-filled Pescadero Creek in Memorial Park in the Santa Cruz Mountains. Saturday night campfire programs are a part of the fun.

Some Like it Hot: Relax and soak away your stress in the lithium-rich waters at way-off-the-beaten-path Wilbur Hot Springs. Stay overnight and enjoy gourmet dining during monthly guest-chef cooking weekends.

Doggy Paddle: The Russian River's best dog-friendly activity happens on an inflatable canoe. Rent one for a few hours and beat the summer heat with your best friend.

Ride the Wind: See those windsurfers on the Bay, fused to their sails, skimming over the waves? Get your feet wet windsurfing with Boardsports School in Alameda where the gentle wind and warm(er) water are easy on beginners.
