Bring insect repellent
Mangroves are mosquito habitat—DEET or picaridin and coverage at dusk will keep bites manageable.
Carry binoculars

Wear non-slip shoes
Boarding and village stops can be muddy and slick—closed-toe, grippy shoes improve comfort and safety.
Timing for fireflies
Choose clear, windless evenings for best firefly displays; heavy rain can cancel or dim the show.
Insect repellent
Repels mosquitoes and biting insects common in mangrove habitats.
Compact binoculars
Helps identify distant monkeys, birds, and river wildlife without approaching them.
Lightweight rain jacket
Provides shelter during tropical showers common in the wet season.
Headlamp with red filter
