All year round
Especially for those who aren't tied to US working patterns, that means it can be truly delightful at any time of year.
In spring there is a gradual switch from snow-based daytime activities to summer ones, when locals switch from snow-skis to water-skis.
In mid September the pace is relaxed, with warm days and cool nights as the arrival of snow is anticipated.
Day to day shopping is catered for with 2 large supermarkets, as well as specialsit sports equipemeent stores for ski hireetc.
North Lake Tahoe in particular is home to a very large number of extremely wealthy second home owners, and commercial architecture style is tightly controlled with no high-rise developments.
This is reflected in the quality of shops ands restaurants, with lots of high-class speciality stores when retail therapy is needed after a hectic day on the slopes or the hiking trails.
And of course there are ample opportunities for refreshment....
..... in Tahoe City alone there are 23 different restaurants - not bad for a town with only 1600 permanent residents.
