Can I kayak or float to Granite Reef from the last take-out point of Salt River Tubing? If so, is anyone interested in doing this? Thanks

Totally. I just did this last night, Goldfield to Granite Reef. Check the Meetup app, you can find several groups that do this fairly regularly.

Yes you can!

Yes, you can definitely do it but I would recommend starting out early in the morning. I've done it before and this way you can beat the heat and catch possible glimpses of wild horses along the river.

You can as long as the dam is open.
