CAUTION: There is a red buoy to the right of center marking a sunken vessel.
4. Marker 7 Green
Wide Waters, Narrow Channel!
About 1 - 1/2 miles from the towers. This is where you need to pay attention. The channel is deceiving with this huge body of water and a narrow channel. Approach this marker no closer than 50 yards to your portside.
5. Marker 13 Green
Marker 13 Green… you’re now 2 miles away!
Approximately 1 - 3/4 miles from Marker 7. When you approach this marker and begin to see homes on the left side of the river, you will have 2 miles to go before arriving at Napa Valley Marina
6. Brazos Train Bridge
You have about 3/4 of a mile to go.
Vertical clearance is 97 feet. This bridge is always in the up position unless there is a train passing through. If it is down just be patient as you are almost there. You have about 3/4 of a mile to go. You will see palm trees in the distance marking the entrance.
7 Napa Valley Marina Entrance!
Careful there is a shoal on either side of the entrance.
Careful as there is a shoal on either side of the entrance. Gas and diesel pumps immediately to the left of entrance. There is 400 linear feet of guest dock beyond the two sets of covered slips.
You are welcome to park your vessel on either side of the guest dock. Remember not to cut the corners of the entrance. It's always better to come with a flood tide. A minus tide will not be favorable for a keeled vessel.
