I just drove through the canyon on Sunday. I don't think there is anyway to run Barrel in a mini-me right now. I wouldn't even try to take a kayak through it. Keep in mind I have never kayaked and don't exactly know how low is too low. It was pretty boney.
The Sho seems pretty decent. I ran it as a raft guide all summer the lowest I ran it was 1200 and it was still ok. There aren't any good rapids below Grizzly Creek till the man made wave.
If you would like to try taking out at No Name give Glenwood Canyon Rafting or Glenwood Canyon Resorts (same people) a call to see if you can take out at their headquarters. That would be the only easy/legal way to take out at No Name.
Things other than rafting to do in the area:
[Click the Independence Pass and Maroon Bells headings for links]
•Independence Pass- a fantastic way to get from Frisco to Glenwood. I grew up in Carbondale and typically drive this to and from school to avoid trafic and I-70 idiots. Call CDOT to make sure it is still open. And be cautious about taking a trailer up there. There are a few sections of one lane.
•Marble- Small town about 45min-1hr up HWY133 (via HWY82). If you have a decent vehicle drive up to the
Crystal Mill. I've seen many Subaru up there. If you have a better 4x4 vehicle do the Lead King Loop that includes the mill. Or just go up to Beaver Lake and take one of their town provided canoes out.
•Aspen- People watch and let the women (if any) shop at all the fancy stores. You should be able to take the gondola up to the top of Aspen Mountain.
•Maroon Bells- One of the most photographed peeks in North America. Absolutely gorgeous this time of year. Just go to the base of Aspen Highlands and catch the tour bus.
•Glenwood Springs- There is the
Adventure Park.
Hanging Lake is a short, high elevation gain hike with awesome views. While I have never done the
Grizzly Creek hike I hear it is beautiful.
Well those are the best things I can think of doing for the day in the Glenwood area. Don't hesitate to ask for other suggestions in the area as I was born and still reside there while not at college.
