I have to drive from San Francisco to Crater Lake with my husband and another couple and it's about 7 hours according to Mapquest. Now, taking I-5 is surely the quick way, but would it be a mistake to miss driving through the Redwoods up past Eureka? We will have already driven the coast from San Diego to L.A., but is it worth it to take an extra 3.5 hours (10 hours total driving one day) to see the Redwoods?
I was thinking San Fran to Crescent City so we could see the Redwoods and then over to Fort Klamath near Crater Lake. I could also go San Fran to Redding and then cut across 299 to Arcata and up to Crescent City, as I've heard that 299 is absolutely gorgeous. Is it too much?
