Sands of Silence: The Petit Bois Island Tour from Dauphin Island
Uninhabited shores, clear water, and a four-hour Gulf escape for up to six.
The morning soundscape belongs to the Gulf—soft, insistent, and alive. At Dauphin Island Marina, gulls orbit like impatient guides while the boat noses into open water, pushing past shrimp boats and the layered silhouettes of Fort Gaines and the Mississippi Sound. The channel widens, the breeze lifts, and the surface turns from pewter to liquid glass. The Gulf is in a good mood today, rolling its shoulders and inviting you to come along. You accept, leaning into the bow’s low hum as the Alabama shoreline loosens its hold.
Trail Wisdom
Sun Smart From the Start
Wear a brimmed hat and UPF layer; the mid-boat breeze can trick you into underestimating UV exposure.
Footwear That Flexes
Pack water shoes or sandals for shell-strewn entry points and hot mid-day sand.
Hydrate Like It’s Summer (Because It Is)
Bring at least one liter of water per person; there’s no potable water on Petit Bois.
Respect Nesting Zones
Give posted shorebird areas a wide berth, especially April–August, and keep noise low near the dunes.
Local Knowledge
Hidden Gems
- •The brackish pond just behind the foredunes—calm reflections on windless mornings
- •The narrow east-end sand spit where currents braid and dolphins often pass
Wildlife
Bottlenose dolphin, Least tern
Conservation Note
Dunes and nesting areas are extremely fragile; stay on firm beach, pack out all trash, and avoid disturbing shorebirds and sea turtle nests.
Petit Bois—French for “little woods”—was noted by early mariners for its sparse tree cover and has been reshaped repeatedly by major storms like Katrina and Camille.

Common Questions
Can we swim at Petit Bois Island?
Yes—swimming is a highlight. Conditions vary by wind and tide, so follow the captain’s guidance and avoid strong currents near inlets.
Are there bathrooms or shade on the island?
No. Petit Bois is undeveloped. Use facilities at the marina before departure and bring sun protection.
Is the tour suitable for kids and older travelers?
Yes. The ride is comfortable and landings are in shallow water. Guests should be steady on their feet for boat entry and walking on sand.
What about seasickness?
Most days are calm in the Sound, but if you’re prone to motion sickness, take preventative medication 30–60 minutes before departure and focus on the horizon.
Can we collect shells?
Collect only a small number of unoccupied shells for personal use and leave all live shells. Follow National Seashore guidelines and your captain’s advice.
What happens if the weather turns?
Safety comes first. The operator may reschedule or cancel for high winds, storms, or rough seas, with options to rebook based on conditions.
What to Pack
1) Two liters of water per person—no freshwater on the island. 2) UPF sun layer and hat—unrelenting exposure on the boat and beach. 3) Water shoes—shells and hot sand can sting. 4) Dry bag—keeps phone, camera, and snacks safe from spray.
Did You Know
Petit Bois Island is part of Gulf Islands National Seashore, established in 1971 to protect barrier islands and coastal habitats across Florida and Mississippi.
Quick Travel Tips
Arrive 20 minutes early for parking and gear organization; confirm your departure time the day before to account for weather; bring cash or card for post-trip snacks on Dauphin Island; cell service is spotty on the water—download maps and info in advance.
Local Flavor
Post-cruise, grab Gulf shrimp tacos and a cold beer at a laid-back Dauphin Island spot like Pirate’s Bar & Grill, then wander the public beach at sunset. History-minded travelers should tack on a quick visit to Fort Gaines for Civil War-era coastal views.
Logistics Snapshot
Closest airports: Mobile Regional (MOB, ~1.5 hours) and Pensacola (PNS, ~2 hours). Meeting point: Dauphin Island Marina. Drive time from downtown Mobile: ~1 hour depending on traffic. Cell service: Fair in town, spotty on the water. Permits: None for passengers; National Park Service rules apply on the island.
Sustainability Note
Barrier islands are dynamic and delicate. Stay off dunes, pack out all trash, skip single-use plastics, and give wildlife generous space—especially nesting shorebirds and sea turtles.
