Lake Worth Inlet, also known as Palm Beach Inlet, is an artificial cut connecting the Lake Worth Lagoon to the Atlantic Ocean in Palm Beach County, Florida. It is a primary access point for paddlers heading to the popular Peanut Island, a man-made 80-acre county park created from material dredged to form the inlet. The inlet itself is a major shipping channel for the Port of Palm Beach, bordered by jetties, with a long one to the south and a shorter one to the north. This results in significant and constant commercial and recreational boat traffic, making it a high-hazard area for kayaks, canoes, and paddleboards. Paddlers must exercise extreme caution, stay clear of the main channel, and be prepared to navigate in active, often congested, waterways.

The most common and recommended paddling route involves crossing the inlet from launch points on the mainland to access Peanut Island. Key public launch areas include Phil Foster Park, located at 900 Blue Heron Blvd. in Riviera Beach, and marinas near Palm Beach Shores. Paddling conditions are heavily influenced by tides and wind. An incoming tide flows from the ocean into the lagoon, while an outgoing tide flows out to sea. Paddlers report that riding the incoming tide provides an easier paddle into the area. Winds can create chop, especially given the open exposure to the Atlantic Ocean at the inlet mouth. The waters around Peanut Island are noted for their clarity, supporting snorkeling and providing views of marine life such as manatees, dolphins, sea turtles, tropical fish, rays, and occasional small sharks. The island features mangrove channels, a rocky shoreline along its southern edge that is a prime snorkeling spot accessible only by paddle craft, beaches, and historical sites like a Cold War-era presidential bunker.

The overall vibe is a mix of bustling activity and natural exploration. On weekends, Peanut Island and the surrounding waters are busy with boats and visitors, creating a lively, social atmosphere. Weekdays offer a more tranquil experience. The area is a year-round destination, with typical South Florida coastal conditions. There are no indicated specific paddling restrictions beyond the universal need for caution around boat traffic. Facilities on Peanut Island include picnic shelters, restrooms, a walking path, and campsites, making it suitable for day trips or overnight excursions.
