Back when we cycled the TA, we'd never seen Crater Lake, so we got off Amtrak to Klamath Falls and cycled first to Crater Lake NP. Then we followed the Umpqua River through Roseburg to the coast at Reedsport just south of Florence, and picked up the TA there. It was a memorable few days in beautiful country. A few days later we met a partner who'd started in San Francisco and cycled the coast route to get there. The point is there are many ways to get to Florence if you're not in too much of a hurry.
