Mare Island has become nesting osprey central May, June and July. There are up to 20 active nests on the island and in the vicinity of the lower part of the river. From the water you will have really nice views of these birds and chicks carrying out their daily activities. We will go up river looking for shorebirds, osprey, and peregrines then head back down the river to the southern end of the island where you will have great views of the Carquinez bridges. As we cruise down the eastern side of Mare Island that’s where the greatest concentrations of osprey and great blue heron nests are located. Generally, these birds can be heard as well as seen and binoculars are highly recommended! A delicious lunch is included onboard while taking in the scenery. You’ll have a choice of: Roast Beef with Havarti, Smoked Turkey with Pesto and Havarti, or Seafood Salad; all served on a croissant with Fruit, Caesar Salad, Non-alcoholic beverage, and a cookie. After the cruise we’ll board the bus for Mare Island Preserve where you may walk a short distance to view the birds and take in the beautiful scenery. We will cruise from and return to the Vallejo marina. This is a rain or shine trip.
