Don’t miss this chance to get a new perspective on Galveston Bay and the historic Port of Galveston. Knowledgeably narrated tours explore the wide variety of birds and marine life that teems in the Bay. (We have no contract with them, but playful dolphins almost always show up to entertain themselves by watching the red-and-white boat and its passengers.) And the human activity in this busy port can only truly be appreciated from the water. A tour aboard the Seagull II is always an hour well spent.


  • Seagull II will not operate during lightning, thunderstorms or sustained winds of 25 knots or higher or if The National Weather Service has issued a Small craft advisory. All other situations, such as rain, waves, Vessel condition and extraordinary circumstances, are at the Captain’s discretion.
  • Seagull 2 will operate in a limited capacity in reduced visibility scenarios. At <1nm of visibility tours will be restricted by the Captain’s discretion, at <1/2 Nautical mile of visibility tours will be postponed or canceled.
  • If the Galveston or Houston channel is closed or restricted by the USCG or Port of Galveston Seagull 2 will follow all directions as broadcasted which could include postponing or canceling tours.

Seagull II makes an excellent and unusual venue for birthday parties, office get-togethers, receptions, convention features, and more. The ever-changing scenery of the busy harbor, the excitement of a dolphin sighting, a restful sunset over an island occupied only by birds, combine to make your event one to remember.

    We took the 4:00 last tour of the day with pleasant weather, sea gulls, pelicans, and plenty of dolphins to be viewed going and coming back to port. We enjoyed the history and sense of humor from Brian and his assistant. We liked and even laughed at his (un-appealing?)banana jokes and added info. We highly recommend this tour.

  13. David Boston

    This was an excellent tour, bad jokes included. We rolled with the flow and spent extra time watching the dolphins but still covered all of the points of interest in the bay, including giving moral support to a guy on a fishing boat reeling in what turned out to be a huge fish. Highly recommend this tour.

  14. Christy Lambert

    We had a blast aboard the seagull II with brian and juan! Very informational and fun! We learned a lot about galveston and pirates and spotted many dolphins along the way. Worth every minute.
