Lake Tahoe is all about unique experiences, and Sierra State Parks Foundation has drummed up four once-in-a-lifetime opportunities that capture just that — all in the name of wilderness preservation.

Picture this: You and three of your friends are seated in the courtyard at the historic Vikingsholm mansion, built in 1929, overlooking the shoreline of Emerald Bay. In front of you on a crisp white tablecloth is a spread of hors d’oeuvres and tall glasses of wine. The sun glimmers across the waters of the iconic bay.

If that idea tickles your fancy, then maybe so will another of the three other custom dining experiences concocted by Sierra State Parks Foundation to raise money for the nonprofit.

Sierra State Parks Foundation, originally founded in 1973 as the Lake Tahoe State Parks Advisory Committee, is dedicated to “educate, interpret, restore and preserve” the parks within the district.

“Cocktails in the Courtyard: A Vikingsholm Experience” is now available for bidding over the next 28 days — unless it’s snagged up for the purchase price of $1,000 before then.

If you’d rather have coffee than cocktails, then look into breakfast on the porch of the Hellman-Ehrman Mansion in Sugar Pine Point State Park. Bottomless mimosas can be enjoyed along with the company of three of your friends. Bidding is underway, or snag the experience now for $1,000.

Trade in the al fresco dining experience for a meal inside the mansion for you and seven of your friends. The highest bidder will choose the menu and wine selection with a caterer. Each guest will go home with a custom engraved wine glass. Bidding starts at $1,000, or it can be yours now for $5,000.

The last dining experience takes place inside the Donner Memorial State Park Visitor Center Museum. Six guests will be wined and dined by Heidi Doyle and Lolly Kupec with home-style cooking and desserts. Place a bid, or purchase it for $1,200.

All funds raised will go toward supporting the organization as it works to maintain and enhance seven California state parks in the Lake Tahoe–Truckee region.
