Key West is Mile 0: the southernmost point of the Continental US, and one of the most incredible places in Florida for sun-seekers. Although the Conch Republic, as it’s unofficially known, has relatively few beaches, you’ll be too busy snorkeling, sailing and fishing to worry about carving out a spot on the sand. If you prefer to embrace island life on land, the vibrant bars along lively Duval Street will position you elbow to elbow with the laid-back locals.

Everglades National Park showcases Florida at its wildest. Snakes, alligators, panthers, crocodiles, manatees and more call the country’s largest subtropical wilderness home. Established in 1947, Everglades National Park was subsequently named a World Heritage site, and you’ll find the serene swamps just an hour away from lively downtown Miami.

Vero Beach on the Atlantic Coast is equidistant from Orlando and West Palm Beach, granting Florida vacationers an additional escape. It’s not unlike other Florida coastal cities, in that the sun and surf are always in season. Whether you play the links or cast a line, there’s always a peaceful place with your name on it, to savor the outdoors. If you’re a nature lover you will especially enjoy checking out McKee Botanical Garden and Pelican Island National Wildlife Refuge.

Sanibel Island has untouched natural beauty and tranquil sandy shores in abundance. There are no skyscrapers or fast-food chains in sight, just breeze-ruffled palm trees and mile upon mile – 22mi (35km) to be precise – of dedicated bike paths. Some 250 varieties of seashell lie surf-scattered on the shore – your cue to go collecting. You might like taking a boat out on the sparkling waters of Tarpon Bay, on the north side of the island. It’s the Florida fantasy in a nutshell (or seashell).

The Ichetucknee is a river that meanders among the wetlands for six or so miles, until it joins the Santa Fe River. It owes its clear water to the eight natural springs that feed it. Full of beautiful green canopies and peaceful river views, the 2,669-acre (1,080ha) Ichetucknee Springs State Park is home to a host of creatures – beavers, otters, wild turkeys and wood ducks. Between October and March you can scuba-dive at the Blue Hole.

Within the boundaries of the Key Largo Existing Management Area, Molasses Reef is easy to reach. Lying southeast of Key Largo, it is one of the most visited reefs for diving in the Upper Keys, home to an extensive and beautiful array of shapes, sizes and other-planetary colors. For scuba divers and snorkelers, there’s the chance to glimpse many types of coral up close – elkhorn coral, billowing brain corals – and you might just encounter turtles and rays, and perhaps the odd nurse shark or two.

Fort Walton Beach is a peaceful, family-friendly beach on the Florida panhandle between Pensacola and Panama City. You come for the sweeping white-sand beaches and the shimmering water of the Gulf Coast, but you stay for all the added attractions and pursuits, including games of golf by the sea and the numerous local parks and museums.

This National Audubon Society sanctuary, just north of Naples, in southwest Florida, was created to protect one of the largest remaining areas of bald cypress and pond cypress in North America from logging during the 1940s and 1950s. A boardwalk just over 2.5mi (4km) long runs throughout the park to bring you up close and personal with pine flatwoods, wet prairie, pond cypress, bald cypress and marsh ecosystems.

This state park is a giant, covering more than 2,600 acres (1,052ha) of land, and encompassing the largest spring on the St John’s River. Blue Spring State Park is the home to the historic Thursby House (built during the steamboat era of 1872), as well as picnic areas and covered pavilions. It is also a designated refuge for manatees – marine herbivores affectionately known as sea cows – and is the winter home to a population of the West Indian (as opposed to Floridian) variety.

Naples Pier, in the city of Naples, is an eye-catching historic structure that stretches out into the Gulf of Mexico. Built in 1889 (the same year as the Eiffel Tower) by the Naples Company, it served as a passenger and freight dock. It has withstood storm damage – even Hurricane Irma – and today it’s appeal is cerebral: inter-generational fishing sessions are commonplace, the youngsters learning from their well-practised elders (you don’t need a license).

Mount Dora is a spectacular place not far from Orlando, oozing small-town charm from every pore. It’s a delightfully sleepy city, with a kaleidoscope of boutiques and antiques, one of the only freshwater lighthouses in Florida and festivals every month. The Annual Blueberry Festival takes place in April, not to mention the big ol’ Fourth of July Independence Day Parade.

When Spanish explorers first landed in Florida and found the waterways full of manatees, they imagined them to be mermaids. You can find the now-endangered gentle giants floating in the water of the Crystal River, a national wildlife refuge. Manatees live in the area year-round, and you can view them from a distance or up close in the water. The most popular area for above-water manatee viewing is the Three Sisters Springs boardwalk.

Roll up to experience America’s oldest continuously occupied European settlement, St Augustine – founded and settled by the Spanish in 1565. The centuries-old architecture is so photogenic. Aim your lens at Castillo, Fort Matanzas, the city gate and the oldest wooden schoolhouse in America. Then take a wander along the cobbled roads, stop for refreshments at pretty cafes and spend the hottest hours in the air-conditioned museums. Don’t miss the 144-block National Historic Landmark District.

Amelia Island is a lovely shrimping village with 50 blocks of historic buildings, fantastic independent restaurants and incredible beaches. If you need somewhere to stay, the island is full of unique bed and breakfasts, such as the adorable, antique-covered Fairbanks House or the beautiful garden paradise of Addison. The island is bursting with Spanish moss and Southern charm. Make sure you stop off at Fernandina Beach (the sea turtle sanctuary) and Fort Clinch.

In the thick of gently sloping greenery in North Florida, this park is the site of a Civil War-era grist mill. The park is filled with towering trees and deep sinkholes. Take the boardwalk Sink Hole Trail to get to Florida’s highest waterfall, which cascades more than 70ft. Visitors might be able to see the colorful flutters of migrating butterflies in the butterfly garden, and other forms of wildlife are everywhere – from grey-furred fox squirrels to brown bats to lurk in the park's many caves.
