The full day trip (as opposed to half day) is highly recommended. The second part of the day includes a really good lunch and a trip down part of the river which is spectacular and less-traveled... we pretty much had the river to ourselves on that portion of the journey. The whole thing was magnificent. Derek and Tom were our guides - Derek in the raft and Tom alongside in his kayak. They are super knowledgeable, resourceful, thoughtful, kind, and funny. All of our dealings with the company were impeccable and the river and scenery were amazing. We have done a LOT of these river rafting trips in various locations. This was by far the best - it was the most exciting and beautiful scenery and the guides were the best ever. Highly recommended!!!!!
