What Travellers Say
Reviews Summary
Visitors praise Dagny Johnson Key Largo Hammock Botanical State Park as a beautiful, peaceful, and less-trafficked natural escape in Key Largo. The diverse plant life and serene trails are highlights, offering a glimpse into the unique ecosystem of the Florida Keys. However, the significant presence of mosquitoes is a recurring concern that can detract from the experience if not adequately prepared for.
"We visited on a Monday morning in late December 2024. There was one other car there when we arrived. We ran into the other person as we were walking in past the gate. He was very friendly and actually talked to us and gave us a bunch of tips.
He mentioned how the trail on the far end was a little submerged and muddy and suggested we avoid that and do the short loops. He also warned us about lots of mosquitos. The temps were in the 60s. The other tip is that the park provides map for you in both English and Spanish but they catch is they attach it to the back of the first info board. So make sure you check behind if you want a nice laminated map and remember to put it back when you're done. We went ahead and paid it forward as we were leaving and another group of people were coming in for the first time.
When you hike in there is pit toilet in between the two parallel trails at the beginning. My wife used it and said it was pretty bad. We've used pit toilets plenty on our adventures and she said you need to be pretty desperate to use this one. It was pretty full.
If you walk a little further there is a really nice Butterfly Garden/Picnic Area which is very pretty and picturesque. The only problem was mosquitos. The local who we bumped into and talked with us had on long pants and long sleeves. We should've taken that as a hint. We did do the Port Bougainville Trail until we hit the spur. We soon realized that we needed to keep hauling it and as long as you kept moving it was harder for the mosquitos to get you. There were some really nice views on this trail but if you stopped more than 10 sec to enjoy the views of the water, you were immediately swarmed by mosquitos. There have been very few other trails we've been on where it was this bad and we've hiked over 100 different trails since COVID all on the East Coast.
This park is a great little hidden gem but the only thing really keeping it from being 5 stars is the lack of mosquito control. We may visit again in the future but not super high priority on our list."

"It's a really nice area for trail walking. Toilet house is outhouse but it was clean and stocked with tissue. There's a really nice garden area for a picnic or just a sit, rest and enjoy spot. On the north end of the full loop it was flooded; so we took the cut to head back down the trail."

"What a beautiful park. We experienced so many different species of plants, and trees. The entire circled throughout forest, and mangroves."

Navigating the Trails and Wildlife
The park is a sanctuary for over 80 protected plant species, including rare tropical trees and wild cotton. While the focus is on botanical preservation, the natural habitat also supports various wildlife. Keep an eye out for signs of crocodiles, though sightings are not guaranteed. The abundance of plant life also makes it a haven for insects, which brings us to a crucial point: mosquitoes.
Many visitors, including locals, strongly advise bringing potent insect repellent and wearing long sleeves and pants. The mosquitoes can be quite persistent, especially during warmer months or after rain. The key to enjoying the trails, according to some, is to keep moving, as this makes it harder for the insects to land. Despite the bug situation, the park offers a peaceful escape and a chance to connect with Florida's natural beauty.
