History

Conservation
Tours operate with low-impact rules—limited group sizes, no off-trail wandering, and minimal lighting—to protect sensitive nocturnal species and reduce disturbance.
Reserve your spot on the Night Walk Tour guided - Biological Reserve today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring a headlamp with red-light mode
A personal headlamp preserves your hands and lets you follow the guide while minimizing disruption; red mode keeps animals calmer and helps night vision.
Wear closed-toe, grippy shoes
Trails are generally flat but can be muddy and slippery after rain—sturdy shoes protect ankles and improve traction.
Dress in long sleeves and pants
Thin, breathable layers protect from mosquitoes and low-temperature drops after dusk without overheating during the walk.
Limit flash photography and stay quiet
Heavy light and noise scare nocturnal animals; follow the guide’s direction for low-impact photos and viewing distances.
Headlamp (red-light option)
Hands-free lighting keeps your vision and the group’s safety intact while reducing wildlife disturbance.
Sturdy closed-toe shoes
