We've done the Black River/YS Falls/Appleton tour from CN and it was great! It was $90pp and included transportation, entrance fees to YS Falls and lunch. You leave for Black River at 9a, and do a river safari. Then, you eat lunch and head up to YS Falls. After YS Falls, it's off to Appleton Estate, which is in a mountain valley with very cool scenery. The ride back is a little longer, about 1hr 45mins, and you're usually back around 4p.
