🇺🇸 One Nation. One Community. One Celebration. 🇺🇸
This summer, Chamberlain & Oacoma invite you to be part of a once-in-a-lifetime celebration as we commemorate America’s 250th Anniversary!
From the 605 Day, American Island Days, River City Friday Nights, Fishing for a Cure, Scavenger’s Journey, and the Pop-Up Military Museum, to a full weekend of patriotic festivities featuring live music, the Patriotic Parade, free Hot Dog Feed, Patriotic Boat Parade, CHS Alumni Weekend, and the largest Rock the Bluffs Fireworks Show we've ever attempted, there is something happening all summer long!
Whether you're a resident, alumni, visitor, or simply looking for a great summer road trip destination, Chamberlain & Oacoma offer exciting events, family-friendly activities, live entertainment, outdoor recreation, and unforgettable Missouri River views.
