Colorado Whitewater does a lot of cruises oriented towards helping new paddlers get in the water Colorado Whitewater - Events
, Filter Plant next weekend is a good one. The group is very patient with new paddlers but also includes people up to class 5. You do need to be a member and contact the cruise leader to let them know where you are at skills-wise.
There is also a regular meetup at Reynold's landing just a bit upstream from you most Mondays, that one usually shows up on Facebook https://m.facebook.com/Colorado-Whit...n-21542292173/
The Monday paddle is usually 5:30 but they're shifting to 3:30 today, not sure about membership for that one (membership requirement is about the insurance, but also supports a really great group of volunteers doing training, advocacy.)
