Griffin Marks, owner and guide of On The Mark Guide Service, offers full-day fishing trips through the scenic river systems surrounding Montesano, Washington. With three years of guiding experience and a passion for helping anglers succeed, Griffin delivers an experience that’s focused, relaxed, and built around the needs and interests of each guest.

Fishing in this part of the Pacific Northwest means access to some of the most consistent runs of salmon and steelhead in the region. Griffin specializes in targeting both, offering guests the opportunity to fish for steelhead, salmon, or even large, wild trophy steelhead depending on the season. His knowledge of the local water and fish movement, paired with a calm and clear guiding style, makes these trips a great fit for anglers of any skill level.

Each trip is eight hours on the water, giving you plenty of time to settle in, learn the water, and chase your target species. You’ll be fishing from a 15-foot Stealth Craft Super Fly drift boat, a purpose-built vessel ideal for rowing quietly through the river while maintaining full control and positioning. The boat is unpowered, which means the experience is quiet, hands-on, and immersive — every moment on the water is driven by skill, technique, and attention to the river’s flow.

Griffin offers different styles of trips based on your goals. Whether you're looking to hook into chrome-bright steelhead, go after salmon during peak season, or focus on catch-and-release targeting of wild trophy steelhead, you’ll be in good hands. All equipment is provided, and Griffin will work with you on methods that match the conditions and your experience level.

The exact meeting time and location change depending on the day and river conditions. After booking, guests will be asked to call Griffin directly to confirm details. This flexibility allows for the best chance at success, as he adjusts to river flows, weather, and fish activity to keep you in the best possible position.

With a limited number of seats on each trip and a personal approach to guiding, Griffin keeps his trips small, focused, and enjoyable. If you’re looking for a serious day of fishing in one of Washington’s most productive areas, On The Mark Guide Service is ready to take you there.
