Special Events &
River Gatherings

Experiences That Happen Once a Year…
or Once in a Lifetime

Some trips are part of the regular season. Others are something entirely different.

Our Special Events bring together unique river experiences, limited-time itineraries, and gatherings that don’t fit the traditional trip schedule. From annual festivals like the Big Water Blowout to new event-based adventures we’re building each season, this is where you’ll find what’s happening now — and what’s coming next.

Check back often or reach out if you’re looking for something specific — these trips tend to fill quickly.
