Once you approach the water the parking is perpendicular to the road and all grass, there are some low areas throughout the park that holds water so I'd recommend wearing footwear that can get wet and still protect your feet, the sand is rocky and the concrete has sharp edges. Unless you have some pre-planned activities you probably won't hang out after getting some step in and enjoying the view, there are a few picnic tables scattered around without shelter...

The park has a attendant to pay for access, but no one was there so we were glad to save a bit of money. Parked the car and we went out to the beach and sat in the sun for a couple hours. Park has restrooms, picnic tables, grills, basketball hoops, playground area and a walkway to the water. Nice little park and was exactly what we were looking for. Saw several people stop and eat lunch and I'm sure they were as happy as we were to find this park. We were there on February 6, 2026.

It also might have been the fact that the boat's engines were so loud that they scared off a majority of the fish we might have seen.  Whatever the actual cause, I suggest that you skip the boat tour and come here to snorkel instead.

So we walk in and look at the map, there's trails to walk, a river to see. We didn't know what to expect, but we weren't seeing much of anything to write home about, so we decided to go off trail to get a closer look at a pretty little stream nearby. Just then a woman in a yellow vest comes walking out of the brush calling out, "Don't worry, I'm a human, not an animal!" She was the most interesting thing we'd seen so far, so we asked her if she worked at the park and she told us the most fascinating story. She's a python hunter! She catches invasive python snakes with her bare hands and puts them in the bags she had tied around her waist, takes them back to a place where they humanely euthanize them, and then the hunter has the option to collect the skins, which she does and makes jewelry out of it. She gets more money catching pythons in the Keys rather than the Everglades because the Keys are harder to get to and find the snakes. She told us more about her life and story to go into here, but I just want to say that while I was polite and listened to her, I am animal rights activist so I am 100% against catching even invasive animals and killing them. Hopefully one day we'll come up with a better solution to this problem. We didn't see any snakes while we were in the park, but just know that they are there. She said they'll probably scurry away from you, but some are big enough to take down and eat whole deer and gators. If you run into her there and she finds a gigantic snake, she may call on you to help her catch it. At least, that's what she told us.

Would be a great spot to have a family gathering or children's birthday party. The actual park is massive. There is a marina, tennis courts, Olympic size pool, soccer field.

There is seaweed under the water. On the bottom of the ocean. Would be fun to be scuba gear! Sand is soft no water shoes needed. Also an outdoor shower near bathrooms :) if you are staying on islamorada show them your reservation for free access to the park. Otherwise I think it's $8 per adult.

We found a seat under the blue tent next to the dock which is used to stage the guess, they start boarding 15 minutes before the departure time and it's really a simple task even though they still manually check-in each guest as you board the vessel verses simply scanning the QR Code on the ticket or app. The 65' Catamaran is clean and spacious and the crew is extremely friendly, the tour guides are very knowledgeable and bubbly so they make every effort to make it fun. You can bring your non-alcoholic beverages on board since they no longer operate the snack bar, they do have (2) heads at the rear of the boat (restrooms). Once the boat leaves the dock it's a slow ride through the mangrove lined canal to the open water, the no wake zone continues until you pass the last navigational buoys, then he kick it up to about 18 knots until he approaches the reef I think that ride was about 25 minutes, it a nice relaxing ride, the interior cabin is air conditioned but the real adventure is on the open air top deck where the breeze is refreshing and you get the real outdoorsy experience. Once the boat arrives at the reef the captain brings the vessel to an idle and the viewing wells turn crystal clear exposing another world, the water depth over the coral reef is between 10' - 25' and the tour guide explains the viewing well numbering system so you know where to look while she explains what the boat is crossing over - she is very knowledgeable and explains everything you see - all the colorful fish and sea-life which is abundant as well as the coral types and objects that rest on the bottom. The tour runs about 2.5 hours and they take no short cuts so you get the total experience. They allow just enough time to get you back to the dock on time and honestly as much as I enjoyed it I was ready for it to be over, the ride back was not as exciting as the ride out and I found myself looking at my watch often - I thought it was a good value and worth the time but once is probably enough for me - the boat was about half filled so it wasn't crowded with about a third being kids and there's no doubt they loved it...

What a nice ride! We were afraid the weather wouldn't let us go! Thanks Mother Nature!…read moreEverything was on time. Clean boat, pleasant guides! In fact, the guide who described the plants & aquatic life while we were cruising over the reef was amazing! Knowledgeable & quick to identify what she saw & its location. They gave lots of info on avoiding seasickness & I didn't see anyone suffering. We took a camera but there wasn't a need. Cell phones are enough. I used my binoculars & only used them a bit to see birds in the mangroves. You can take plastic bottled drinks on board. You might not want to wear a hat. We stood on the front deck & it was perfect. It's with the $36 ticket for a 2.5 hr. excursion. Masks required inside.
