When the sun sets over the Arenal Volcano, a completely different world wakes up. While most tourists are heading back to their hotels for dinner, the tropical rainforest is just beginning its most active shift. Over 60% of Costa Rica’s wildlife is nocturnal, meaning that if you only visit the trails during the day, you are missing out on more than half of the action.
If you are curious about exploring the jungle after dark but have a few questions about safety, what you will see, or what to wear, this guide is for you. Here is exactly what to expect on an Arenal night walk in La Fortuna.
1. The Symphony of the Night (A Sensory Experience)
The first thing that will surprise you about a night hike is the sound. The moment you switch off your flashlight for a few seconds, you realize the rainforest is incredibly loud.
The background music is powered by thousands of cicadas, crickets, and the distinct, hammer-like call of the Tink Frog. It is an immersive sensory experience that makes you feel tiny and connected to nature in a way a daytime walk simply cannot match.
2. The Wildlife You Can Only See After Dark
Many of Costa Rica’s most iconic and colorful creatures are masterfully hidden during the day but become active hunters at night. On a private reserve hike, your guide’s spotlight will help you spot:
Red-Eyed Tree Frogs: The undisputed stars of the night. During the day, they tuck their bright colors away under leaves, but at night, they flash their vibrant red eyes and orange feet.
Sleeping Birds: It is fascinating to see colorful toucans, motmots, and clay-colored thrushes sleeping soundly on low branches, completely oblivious to the world.
Nocturnal Mammals & Insects: From glowing fireflies and fascinating tarantulas on the tree trunks to the occasional opossum or kinkajou moving through the canopy.
3. Safety and Terrain: Is a Night Walk Dangerous?
This is the number one question travelers ask. The answer is not if you go with a local expert on a controlled trail.
When you book a night tour in Arenal at a private reserve like La Fortuna Hikes and Trails, you are walking on clean, dynamic, and well-maintained paths. You will not be hacking your way through wild jungle with a machete. Your naturalistic guide knows the terrain perfectly, carries professional lighting, and ensures the group stays safe and comfortable from start to finish.
What to Wear and Pack for Your Night Tour
To make sure you enjoy the experience without worrying about bugs or weather, make sure to bring:
Closed-toe shoes: Hiking boots or running sneakers are mandatory (no sandals or flip-flops).
Light long pants: To protect your legs from brush and mosquitoes.
Eco-friendly insect repellent: Apply it before entering the trails.
A light raincoat: Rain showers can happen at any time in the Arenal area.
