ACS Clinical Congress 2026

In late September, Washington's summer heat fades into crisp, golden afternoons—ideal for strolling the National Mall between sessions, where the monuments and Smithsonian museums are just steps from the convention center. When you're not inside, dive into the city's vibrant dining scene: grab a half-smoke at a historic chili spot or sip a local craft beer in a leafy Dupont Circle beer garden. Autumn here brings a quieter, more contemplative energy, making it a perfect backdrop for focused learning and meaningful connections.
