Heading to Utah in mid-June. My wife and I have always liked renting kayaks on the ocean and just paddling off and doing our own thing. We'll be car camping for 2 weeks and this will just be one of the stops (mostly mountain biking in Moab/Red Canyon, and hiking in Zion). We were just planning on taking a day (maybe 2) at Lake Powell to kayak for 4-5 hours. I normally don't dig tours much and more interested in kayaking for a day rather than paddling out to a place to camp. Realize Lake Powell is huge. I'll have a VW Jetta Wagon with a Yakima roof rack loaded with mtn bikes. I don't neccesarily need to kayak Powell, but would like to paddle in a slot canyon. Would love some advise on where to go, where to rent, and where to camp.
