As the Ice Age Floods National Geologic Trails has dozens of parks and museums across 4 states, the operating hours and seasons can vary wildly. We recommend reaching out to any sites you want to visit while you plan your trip, and check their hours. Check out our Things to Do page for a list of museums, and our Places to Go to for a list of parks. For unmanned sites, the general rule of thumb is that they are closed from dusk until dawn everyday.
