I love taking advantage of the proximity to all of the ski areas. Decide everyday where the best snow and weather are, and go there. Remember to pack bathing suits in the car, so you can head to the jacuzzi on your way back home from the mountains or town... or maybe eat at one of the awesome restaurants at the ski areas or around Truckee, Tahoe City or Kings Beach.
As much as Winter in Tahoe is fabulous, Spring, Summer and Fall visits allow for hiking, biking, rock climbing, swimming, tennis, golf - there are several world class golf courses nearby, visiting the hot springs in Sierraville, exploring local history, boating and playing at the lakes (Donner and Tahoe). Also, check out nearby reservoirs.
There is always State Line or South Lake for a bit more excitement, and so much more it would take too long to add it all in here.
For my young family, we spend a lot of time hanging out and enjoying the house, the views out the window, and the Tahoe Donner amenities. We hope you will too!
