Raining like crazy up here
Great advice on other post tomgo yo the trinity, went 5 times in December after torrential rains, was still gin clear past del loma throughjunction city, that area is awesome, all kinds of forest service campgrounds, skunk point, bagdad, right on river and super cheap, bathrooms, really nice fir budget. Each run prettier than one before, great access, sunny.
If old growth redwood forest is what you want, and it doesn't rain fir at least a week (river will me mud otherwise) and you saw "swing north" like me, the avenue of the Giants near redcrest will have you walking through virgin old growth forests to the river just like mike Wier and Jason hart wick in the movie. Weather will probably be wet , cold , and damp, trinity you will be wearing sunglasses.
Two totally different experiences, have fun!
