Mount Vernon, Washington, sits on the fertile floodplains of the Skagit River, just a short drive from Washington's rugged coastline and Puget Sound. Though the region brims with water-adjacent adventures, snorkeling tours near Mount Vernon are not a recognized or widely available recreational activity due to the area's cold waters, low visibility, and lack of suitable snorkeling sites directly accessible from the city. The waters here, shaped by powerful tides and currents, tend to challenge casual swimmers rather than invite leisurely exploration beneath the surface.

For those seeking underwater adventures, nearby locations such as the San Juan Islands or Puget Sound areas around Seattle provide more established snorkeling experiences, offering clearer water and diverse marine life encounters. These spots are generally better equipped for snorkeling tours with professional guidance, suitable water temperatures (in summer months), and infrastructure to support visitors.

Mount Vernon itself, while a gateway to outdoor activities, is better known for hiking, bird watching, and riverfront recreation than for snorkeling. The Skagit River and surrounding wetlands offer vibrant ecosystems but are not ideal for snorkeling activities.

Visitors looking to explore the marine environment near Mount Vernon should consider day trips to nearby Puget Sound coastal towns where tour operators offer guided snorkeling excursions focused on viewing sea stars, nudibranchs, and anemones, or enjoy kayaking the serene waters with occasional glimpses beneath the surface.
