Where is Trinity River Valley and what is there to do for visiting families?

Answer 1

This is an extract from wikipedia:

The Trinity River is the longest tributary of the Klamath River, approximately 130 mi (209 km) long, in northwestern California in the United States. It drains an area of the Coast Ranges, including the southern Klamath Mountains, northwest of the Sacramento Valley. Considered especially scenic, along most of its course it flows swiftly through tight canyons and mountain meadows.

Whether there is anything there for families, I do not know, but doing a search on it might get more info.
