Big Basin is California’s oldest State Park established in 1902. Created to preserve these extraordinary ancient coast redwoods.
It’s a popular State Park close to San Francisco, but less busy than Muir Woods. Somehow crowded at weekends and popular for camping under the astonishing trees. It’s a park you should not miss. During winter it gets wet and trails are slippery and muddy. Nevertheless, hikes can be done all year but ask for trail conditions first.
The wet season starts in November and lasts until February with most precipitation in January. It receives three times the rainfall of the Bay Area. This rain is much needed by the redwoods after the dry summer. The average night temp is around 41°F / 5°C and day temp under 60°F / 15°C.
Summer from June to September is mostly dry with dense summer fog in the morning. The mist provides the trees with moisture. Nights temps are much cooler than in the Bay Area with around 49°F / 9°C and day temps about 74°F / 23°C. Anyhow, in the hot summer months, it can reach up to 86°F /30°C and more.
Where to Stay
You can either camp for $ 35-50 which includes the State Park fee of $ 10 under the ancient redwood trees or choose the charming The Inn at Saratoga ideally situated. Included is a cold buffet breakfast.
I've backpacked in the Kings Canyon area twice, in May and September, which are what I would consider the bookends of the season. Any colder, and this would be for serious Winter lovers only.
May through October
