FREE things to do
Yes, you can have an excellent time in Napa Valley on the cheap or even free. Check with your credit cards to see if they offer deals on wine tastings. Many do. Also, pick up free advertising publications at the visitor's centers for coupons and other offers.
Some wineries have free art exhibits:
Hess Collection - three levels of modern art FREE!
Inglenook - Francis Ford Coppola's collection of magic lanterns and early animation machines. FREE!
Mumm - Ansel Adams gallery FREE!
These museums are free, but encourage donations:
Robert Louis Stevenson Museum - For the love of Robert Louis Stevenson, who honeymooned in upper Napa Valley, the museum houses a collection of memorabilia, an archive of original manuscripts and letters, and a library of rare books.
Sharpsteen Museum - This local museum showcases the rich history of Calistoga and the upper Napa Valley. Intricate dioramas of life in the 1860s are particularly extraordinary.
And, Calistoga, St. Helena, Yountville and Napa all offer free concerts in the park during the summer months.
Of course, a hike in the wilderness is always a good way to discover the land too. Bothe Napa Valley State Park in Calistoga and Skyline Wilderness Park in Napa deliver trails, creeks and even redwoods.
