This was the highlight of our 40th anniversary trip to SPI, in fact the entire trip. We took the four hour Port of Brownsville Tour. It was fantastic, educational, and fun. The tour travelled from South Padre down the bay to the Port of Brownsville. It passes by the Space X launch site. We saw lots of dolphins, channel dredging ships, an LNG establishment, ships being taken apart, and ships bringing imports and exports to the Port of Brownsville. During the tour, coffee and donuts were served, and then on the return trip, a tastinf of fresh gulf shrimp! Be aware that if you are on the outside at front and side of the boat, you will get wet by the spray. There is an inside cabin or you can chose to go up top. Captain Patrick was an informative narrator with a great sense of humor and wonderful music playist. We laughed as we leared. The crew of Angie and Anthenoy were friendly, fun, knowledgeable, and exceeded expecations. It was a great way to end our trip to SPI! I highly recommend this tour!
