Welcome to Colorado! My little town of Buena Vista is about an hour and a half from there up in the hills. I’ll definitely be up for some trips if you’re ever game.
If you’ve never seen it, check out www.mountainbuzz.com. It’s a forum for all things related to floating down the river. I haven’t seen much ‘packraft’ specific stuff on there but they do get about a million times more traffic than this site seems to. It covers the entire country but was started in Colorado and definitely has a rocky mountains emphasis.
I’m planning on some sort of trip to the Dolores river May 12ish if you have any interest. Plan A is to do Slickrock to Bedrock, a super pretty 3 day float with a handful of easy class II/III. This would be more a traditional river trip, requiring a shuttle, but I plan to pack light and take my packraft. I still have to see what shuttle options I might have, especially if it’s just me. My other thought is to just park at the takeout and hike up as far as I can. There is an awesome looking side canyon about 3 miles up called La Sal creek. I have absolutely no idea if it ever has enough water to float, can’t find anything online so far. But there is a trail up it and some hiking reports/pictures make it look like it might be possible during runoff.
Anyway, let me know if you ever want to get out.
