Arenal Volcano is the most iconic and recognizable landmark in all of Costa Rica. For decades, it was one of the most active volcanoes in the world, famous for its nightly glowing lava shows. Although it went back to sleep in 2010 and stopped erupting, it remains a majestic and powerful sight.
Whether you want to hike over ancient lava fields, swing through the jungle canopy, or relax in natural hot springs, this region has it all. Here is your guide to exploring Arenal Volcano National Park!
Ultimate Guide to Exploring Arenal Volcano National Park
Hiking the Historic Lava Trails
You cannot visit this national park without hiking on the historic, hardened lava fields. The park offers several beautiful, well-maintained trail networks that wind through the dense rainforest and open up to the volcanic base.
The most famous route is the Arenal 1968 Trail, named after the massive, unexpected eruption that transformed the landscape. Walking over these sharp, black volcanic rocks gives you a sense of the earth’s incredible, destructive power.
As you hike, you will notice a fascinating contrast between the barren, dark lava rocks and the bright green jungle slowly growing back over them. Once you reach the highest observation points, you will be rewarded with sweeping views of the volcano peak and the massive lake below.
Because the tropical weather here is unpredictable, the towering peak is frequently hidden. To get the best views, try to arrive at the park entrance right when it opens at 8:00 AM, before the thick midday clouds roll in and cover the volcano.
Soaking in the Geothermal Hot Springs
After spending a long morning hiking over rough volcanic rocks, your muscles will need some deep relaxation. Thankfully, the massive geothermal activity happening deep underground heats up a network of natural hot springs.
The area surrounding the volcano is packed with world-famous hot spring resorts, ranging from massive family waterparks to ultra-luxury romantic retreats. Places like Tabacon and Baldi feature dozens of steaming pools hidden beneath beautiful, manicured jungle gardens.
There is nothing quite like sitting in naturally hot, mineral-rich water while a cool tropical rain falls from the sky. Many of these resorts also feature swim-up bars, allowing you to sip a tropical cocktail without ever leaving the warm water.
You do not have to pay expensive resort fees to experience this natural luxury. If you want to save money, grab a towel and head to the free, natural hot spring river located in the jungle right across the street from the Tabacon resort.
Exploring the La Fortuna Waterfall
Just a short drive from the base of the volcano lies one of the most spectacular waterfalls in Costa Rica. The La Fortuna Waterfall is an absolute must-see destination for anyone visiting the Arenal region.
Visiting this natural wonder requires a bit of physical effort, as you have to hike down a steep staircase consisting of 500 steps. The walk down through the thick, vibrant green rainforest canyon is stunning.
At the bottom of the stairs, you are greeted by a massive waterfall plunging 200 feet down a sheer cliff face into a bright blue pool. The sheer force of the water crashing down creates a refreshing, cool mist that fills the entire canyon.
Swimming in the crisp, cold jungle water is the perfect way to cool off after the sweaty hike down. The current under the waterfall is strong, so make sure you only swim in the calm, shallow pools just slightly downstream from the main drop.
Spotting Wildlife on the Hanging Bridges
Arenal is not just about geology; it is also home to one of the most diverse and vibrant rainforest ecosystems in the world. However, much of the wildlife lives high up in the treetops, making it hard to see from the ground.
To solve this problem, you should visit the Mistico Arenal Hanging Bridges Park. This private reserve features a series of high suspension bridges that allow you to walk right through the middle of the jungle canopy.
Looking down from these swaying bridges gives you a breathtaking bird’s-eye view of the forest floor and the volcano in the distance. It is the absolute best place in the region to spot howler monkeys, colorful toucans, and sleeping sloths.
While you can hike these bridges by yourself, you should hire a local naturalist guide for the tour. Their trained eyes and professional spotting scopes will help you see tiny frogs and hidden snakes that you would otherwise walk right past.
Navigating Lake Arenal
Sitting peacefully at the western base of the volcano is Lake Arenal, the largest freshwater lake in Costa Rica. This massive body of water provides a different perspective of the surrounding volcanic landscape.
The calm waters on the eastern side of the lake are perfect for peaceful water sports. You can rent kayaks or stand-up paddleboards and glide across the surface, watching tropical birds dive into the water for fish.
On the western side of the lake, the wind picks up significantly, creating world-class conditions for extreme sports. During the dry season, thrill-seekers from all over the globe travel here specifically for windsurfing and kiteboarding.
If you just want to relax, book a guided sunset boat cruise across the water. Viewing the massive volcano from the middle of the lake provides the most spectacular, unobstructed photographs you will take on your entire trip.
Essential Packing and Weather Logistics
To successfully explore the Arenal region, you must pack for multiple different microclimates. The weather here can shift from burning sunshine to torrential rainfall in a matter of minutes, regardless of what the weather forecast says.
You should pack lightweight, quick-drying athletic clothing that will keep you comfortable in the intense humidity. A pair of sturdy, waterproof hiking shoes is also mandatory to safely navigate the slippery, muddy jungle trails.
Do not forget to apply reef-safe sunscreen and strong insect repellent every single time you step out of your hotel room. The mosquitoes in this lush, wet environment are very aggressive, especially around the hot springs and the lake.
Because the tropical rain is so sudden and heavy, standard umbrellas are useless in the jungle. Always keep a high-quality dry bag inside your backpack to protect your cell phone and camera from sudden afternoon downpours.
Conclusion
Arenal Volcano National Park is the adventure capital of Costa Rica, offering something magical for every type of traveler.
Standing in the shadow of a massive, sleeping volcano reminds you just how wild and powerful the earth truly is. It is an awe-inspiring experience that you will remember!
