The Curry Hammock Nature Trail is a roughly 2-kilometer-long loop trail through a rare tropical rockland hammock habitat. Dense forest grows on the uneven coral cliffs, home to exotic palm trees, shrubs, and bird species that are otherwise hard to see. 🚶‍♂️ The trail leads along a narrow path through tranquil nature all the way to Florida Bay, where you can enjoy stunning views of the water—especially in the evenings. 🦋 Along the way, you'll encounter butterflies, birds, and sometimes even small lizards. At the same time, you should be careful: the ground is rocky, sturdy footwear is a must, and some plants, like poisonwood, can be unpleasant. ℹ️ The trail doesn't start directly at the park entrance, but at a small parking lot on Bayside (off US-1). There are no restrooms, and mosquito repellent is provided in the summer—so don't forget your insect repellent.

On the north side of the Old 7 Mile Bridge, there's a picnic area with two covered shelters. Fishing is also possible here. There's a parking lot. It's also ideal for continuing on to the Lower Keys.

The Old Seven Mile Bridge is one of the most famous structures in the Florida Keys. It was originally built in the early 20th century as part of the famous Overseas Railroad, which Henry Flagler had built from Miami to Key West. It was later converted into a road bridge before being replaced by the modern parallel bridge for automobile traffic. Today, a section of the old bridge is open to pedestrians, cyclists, and runners. From here, you can enjoy magnificent views of the ocean, the islands, and the new Seven Mile Bridge running parallel to it. The walk to Pigeon Key, a small island with a museum and historic buildings, is particularly popular. There are parking areas and shaded picnic areas at the entrance, ideal for a break before or after your tour. The bridge is a popular place to take a break before or after your tour.

Sombrero Beach is a quintessential Florida Keys beach. Soft white sand, crystal clear water, and plenty of facilities for your day at the beach. If you're biking out here, plan to stay a while.

As on the last visit, the water was extremely high. At least we got to the water today - with a little effort!
