We enjoyed the park visit overall. The various quarries and fossilized corals were interesting. The mosquitoes were not bad the day we were there. But the Golden Orb spiders were EVERYWHERE! They are beautiful but you have to take care to avoid their webs - apparently they were unusually plentiful during our visit due to the wet conditions (thus lots of bugs to eat) earlier this year. The staff is very nice and they have laminated guidebooks to take onto the trails with you for the self-guided tour.

“Fascinating. Unique.”
Reviewed December 10, 2013

This was a highlight of our brief, but exciting visit to the Florida Keys. One can see the results of extracting coral rock from three different quarries including the one used for taking fill for building the railway over a century ago. In addition to that, however, there are several paths where with the self-guiding trail books one can learn about the fascinating range of flora that flourishes on the thin topsoil covering the coral limestone bedrock. Although you can hear the traffic on the Overseas Highways just a few metres away, there is sense of escape into the very interesting past of the Keys that we look forward to learning more about in the future.

“Nothing special”
Reviewed November 21, 2013

Although the purpose of the park is the geology of the keys, the main focus of the trails is the fauna. Lots to learn, if that's your interest. Avoid if you don't like LARGE spiders (we do and thought that was the best part of the visit).

“Wonderful attraction, but not if you hate spiders.”
Reviewed November 12, 2013

I wish I had read Tripadvisor before our visit, but we were directed here by the tourist center in Islamorada. I thought it would be nice to walk in the woods after eating so many wonderful meals on our trip. The spiders ruined it for me. THEY ARE HUGE! And poisonous. Like I'm going to get close to them. I did take pictures because we don't have spiders like that in Missouri. The spiders are above and beside the trail. The rangers said there had been people earlier than us who would have walked through the ones across the trail. Sheesh. (I think the poor girl who cleared the path also left a review.)

The rangers were wonderful and the tourist center was clean, organized, and informative. We were there on Veterans' Day and they weren't charging admission, which was a surprise. The bathrooms were clean and well-stocked.

We didn't walk through the quarry, because 1) I was very freaked out after the spider trauma and 2) there was no shade and I'm very fair. If you're up for a walk on Survivor Island, this place won't faze you at all.

“Interesting History”
Reviewed November 11, 2013

Okay, I'm going to be nice here. The ranger was great, the visitor's center was extremely informative and neat, the quarry that Flagger used to construct the railroad going down to the keys was amazing. But, and this is a big but...if you don't like spiders, DO NOT go down the two paths that they have.

I am terrified of spiders, and as long as they were off to the side I was scared, but okay. Then when a web was across the path, hubby worked to pull it off to the side and told me to run on by, which I did, and stopped in my tracks when I immediately ran into another web across the path. That's when I was done. Period. So we tried the second path. Even worse.

We went to the quarry next, not many trees, no spiders or webs, and the fact I was looking up at 8' of coral that Flagger used, knowing the water had to be much higher, was amazing. I was really impressed. Nice historical place, just not for the faint of spiders. There were other paths but I wasn't willing to take them....shiver...

Oh, and they don't take plastic, only cash. The fee is $2.50 each, they sell some of the keystones ($1.50 each) used in the area, and they have bathrooms, soda machines, and water fountains.
