    Tarpon Springs for the day and went on this hour long boat ride. The family and staff were wonderful - friendly and informative. During the tour, they did a demonstration of sponge diving. It was great to see and you gained appreciation for the hard work that these families did for many generations. This boat tour is a must to do when visiting Tarpon Springs.

    My St. Pete ladies meet up group of 20 ladies, did a day trip excursion with Nicholas Boat Lines. Not only was it a fun day, we learned about the sponge industry, saw dolphins, saw the home that was used in the movie Under the 12ft Reef & got 2 demonstrations of the scuba gear used long ago. Our crew was so much fun. I'd highly recommend anyone looking to go out on a quick half day trip go with this multi generation family run business.

    We were just walking around Tarpon Springs to 'check off a box' of having been there. At last minute- we decided to take this tour just to see it. What an unexpected pleasure! It was I formative and obvious the gentleman that runs the business cares about what he does. We had a great time and learned a lot!!

    Outstanding tour. Only $16 for an hour. Tons of information about sponge industry, history, culture, etc. And a live diving demonstration. .

    I am so glad that we went on this excursion. It's one of the best decisions we made while at Tarpon Springs. Before this tour, my husband and I were walking around confused by the different types of sponges and the history of the area. After this tour, I had a much greater appreciation for Tarpon Springs. We didn't find the tour cheesy or gimmicky. There was no back and forth banter between the diver and crew, but more of a straight forward lesson from the diver himself. This tour gave us a quick history lesson and break down of the most common sponge types you see in the shops. We also got to hear about what the live sponges look like under water, and how they are then processed for use. The diver also explained in detail what we would see during his dive in the old dive suit, and the crew informed us where to stand in the boat for the best photos. The boat ride is quick and you don't go out very far to the true diving areas since those are many miles into the gulf. At the time that we went (Feb 2019) the price was $12 per adult. I'd highly recommend it. Also, keep your ticket for 10% off at a nearby restaurant.

    While this is the shortest boat ride, at 45 minutes I've been on in Tarpon Springs, it really stands out as a great trip. Everyone was so nice and welcoming. The driver Doug was so great with all the kids taking time to explain things and to pose for pictures. I didn't find anything cheesy on this trip as other reviewers have noted. I've gone out on a boat ride in Tarpon Springs every year for the past 10 years at least and I learned many new interesting things today. I would recommend this trip without hesitation. The trip would be good for any ages and groups.

    Taking a boat ride on the St. Nicholas Boat Line is a humorous, but educational experience. Yes, the one-liner bantering between the ship's narrator and the sponge diver is a bit cheesy, however the whole experience is a lot of fun. The folks who operate this boat, including the diver, are all Greek residents of Tarpon Springs, and they told us a lot about life in this fishing and sponge diving community, just north of Tampa. You'll find this boat moored at the Sponge Docks along Dodecanese Blvd in Tarpon Springs, and there are people out in front of the Sponge Diver Supply store who will sell you the tickets for $8 for Adults. The trip lasts about a half hour, and though it feels very touristy, you'll learn a lot about the history of Tarpon Springs, and the history of Greek sponge diving. After the boat pulled away from the docks, it putters down to a sponge bed inside Tarpon Bayou, and the diver begins his work. This guy climbs into a canvas diving suit weighted down with lead shoes, a lead breastplate and back plate (about 45 pounds all together), and then straps on a 100 year-old brass diving helmet, tethered to an air hose on the surface, and goes over the side to walk along the bottom and search for a live sponge to harvest. Within moments he finds a fist-sized sponge on the bottom, and hauls it up for the tourists on the boat. They explain that the sponges are living creatures, and that they'll re-grow a new animal in that same spot, and a few months later it will also be ready to harvest. On the cruise back, they showed us a basket of different types of sponges (available for purchase at any of the shops along Dodecanese Blvd), and explain their use for general bathing, washing your car, cosmetics application, and so on. Our narrator pointed out some of the homes along the channel, and mentioned some of their favorite restaurants in Tarpon Springs. Yes, it can be incredibly hokey, but we had a nice time and enjoyed the cool breezes off the water.

    Explaining the different types of sponges. TIP - If you want your sea sponge to last, do not use bleach!

    Honestly, it's a little cheesy, but somewhat interesting. They barely take you more than a few hundred yards from the marina dock when a guy in a 100 year old helmet diving suit plops in the water, walks around under the surface for a few minute and comes up with a nasty little sponge that you get to touch (and by nasty I mean covered in black slime). They give you a few facts about sponges and the history of sponging in the area, but really the only cool thing about this 25 minute tour is the super old helmet suit. Small children will probably find this activity the most exciting. If you are looking for a longer adventure, I would recommend the Dolphin Tour to Anclote Island with Odyssey Cruises for a few bucks more. We did both. Adults | $8 Kids (6-12) | $4 6 & under | free FINAL THOUGHT It's tolerable if you are looking for something to do other than walk the local shops & restaurants of Tarpon Springs. Staff is very friendly so that's plus, but at the end of your tour expect to be presented with a pack of post cards. At first you'll think they are a gift for taking the tour, but just hold on a few minutes. It will become apparent they are for sale as one of the crew members begins to promote them (helmet guy will sign one for you if you buy). We bought one pack since it was only a buck, however its been a few months now and I can't remember where I put them! LOL

    n 1905, Greek spongers came to Tarpon Springs, Florida, to develop the world's largest sponge industry.

    Sure, it's a bit cheesy as others have mentioned, but I had fun, and so did my daughter, so isn't that the most important thing? We also spent less than $20 for this period of fun. On her father's side, there are sponge divers in the family, so it actually had some familial significance for her. The sponge diver and the owners of the cruise line all knew her grandfather from his time living there and working on the boats, so she started getting a bit too cocky in name-dropping everywhere we went, but it made her feel like a celebrity. The St. Nicholas Boat Line was established in 1924 by Captain Michael J. Billiris and continues to be operated by the Billiris family. It is the second oldest attraction in the State of Florida. The St. Nicholas VII is a US Coast Guard Certified Vessel. Doug, the sponge diver, made the journey for kids and families extra special, by taking the time to pose for several pictures. He posed with his helmet on, and without it on. It was very interesting to learn that the diving suit weighed over 100 lbs. once all the weights, helmet, and everything was added on (172 lbs., if you want to be specific). This was one of the most dangerous jobs in the world, so you can appreciate all that went into diving for sponges. Doug prepares himself as Michael John, the host, explains all that must go into ensuring the suit is ready, and the diver is safe. There are shoulder weights involved, a chest plate, as well as making sure the rope around the waist is on tight. The footwear alone weighs over 10 lbs.! I cannot imagine how hot it must have been wearing that thick suit, followed by the helmet and the air hose. Doug slowly descends, prepares to go deep under water, and looks for a sponge. He then climbs up a ladder that the captain puts down for him, brings up the live sponge, and poses for pictures with his new find. Michael John explains that a crew of six might be out at sea collecting sponges for three weeks or three months, a fact that still makes the job an unpopular career choice. The slimy, wet sponge is passed around for all to touch, and they explain that the sponges you purchase or see in the markets are actually the skeleton of the living creature you're touching. They also pass around different types of sponges while making this presentation. These include wool sponges, finger sponges, and decorative sponges that can be used as a centerpiece, or as a flowering pot. Everyone was fascinated (and some kids grossed out), to find out that the sponge they use in the shower is actually a skeleton. The tour is informative, quick, and sweet. The price is also just right. These people rely on these tours for a living, and they were hit hard after Hurricane Hermine passed through, caused flooding and blocked off streets, and had to close for a few days. It was therefore no issue for me to spend $1 on their postcard pack promotion at the end of the tour, and my kiddo got the diver's autograph on a couple, making the experience even more authentic and entertaining for her! This is a must for a tourist visiting the area, and wanting to learn more about the history that made this city, in my opinion.

    Fun and entertaining for the whole family. Learn how sponge harveting began. I highly recommend this 40 minute boat tour!!!

    What great fun and educational! Frank the sponge diver and his crew tell of days gone by of how Tarpon Springs became the Sponge Capital of the World! Fellow sponge divers from Greece came from abroad to work in this area and have now made this their home. A lot of history in these guys! Loved the tour! Frank actually dives like the old times and gathers a sponge for your review!!

    I'm recovering from knee replacement surgery. How hard is it to get on and off the boat?

    i use a rollator and was very hesitant about going on the boat with the rest of our tour group. However, three crew members helped me navigate the steps on and off the boat. They were very kind and helpful. It wasn’t easy, but it was so worth the…
