Florida Keys Inside (ICW) Route: Card Sound to Islamorada, FL

For boats that draw no more than 5 feet and can take the occasional short, hard chop of shallow water, the Inside (ICW) Route on the bay side provides a relatively well protected and interesting passage option to Islamorada, Marathon and beyond to Key West.
This route is clearly marked; however, for certain stretches the markers are far apart and careful attention is required to stay in the controlled channel.
The inside route gives boaters access to popular Key Largo and the famous Everlades National Park backcountry. Take a dinghy or kayak trip to explore the area's beautiful mangrove tunnels.

When Commodore Ralph Middleton Munroe was sailing and exploring the Keys at the turn of the 20th century from his home on Biscayne Bay, he ducked in and out of Hawk Channel through the myriad channels along the islands and spent many nights anchored in their lees.
The Commodore's reminisces of the settlements and people of that time are delightful reading and portray Florida as a new frontier and destination for visitors seeking warm weather and a tropical paradise.
Today, the Keys remain worthy of discovery and those who make the journey are seldom disappointed. Boating, kayaking, cruising and biking in the Florida Keys are just as magical as they have always been.
