Did you know that Trinity Island, part of Louisiana’s Isles Dernieres Barrier Islands Refuge, was completely restored just one week before Hurricane Ida made landfall in 2021 and successfully withstood one of the strongest storms to hit Louisiana? This remarkable 5.5 km (3.4 mile) long barrier island serves as a critical first line of defense against hurricanes, protecting coastal communities in Terrebonne and Lafourche parishes while offering visitors a unique blend of natural beauty, wildlife viewing, and outdoor recreation opportunities.

Getting There & Planning Your Journey

Reaching Trinity Island requires some planning as this remote barrier island is accessible only by boat. The closest major airports are Louis Armstrong New Orleans International Airport (MSY), approximately 128 km (80 miles) east, and Lafayette Regional Airport (LFT), about 112 km (70 miles) north.

From either airport, you’ll need to drive to one of the coastal launching points in Terrebonne Parish. The most common departure points include:

• Cocodrie, Louisiana – offering charter boat services and kayak launches
• Dulac Marina – providing boat rentals and guided tours
• Pointe-aux-Chenes – with several local fishing guides who know the waters

Charter services typically require advance booking, especially during peak seasons. Most tours to the island take 1-2 hours each way, depending on weather conditions. If you’re an experienced boater, you can also rent a boat and navigate to the island yourself, but local knowledge is highly recommended due to the changing coastal conditions.

Best Time to Visit & Weather Tips

The ideal time to visit Trinity Island is during spring (March to May) and fall (September to November) when temperatures are pleasant and wildlife viewing opportunities are abundant. During these seasons, temperatures typically range from 18-29°C (65-85°F) with moderate humidity.

Always check weather forecasts before planning your trip, as conditions can change rapidly in this coastal area. The island offers little shelter during storms, so tour operators may cancel trips during inclement weather for safety reasons.

• Charter boats – which can transport you between different parts of the island
• Walking tours – led by knowledgeable local guides who explain the area’s history and ecology

There are no paved paths or roads on the island, so wear appropriate footwear for walking on uneven terrain. The island is also constantly changing due to erosion and restoration efforts, so areas that were accessible during previous visits may have changed.
