What changes when hiking in Costa Rica during the rainy season is the experience itself. Trails get wetter, humidity rises, visibility changes throughout the day, and you’ll want to leave some flexibility in your plans.
Rainy season here doesn’t usually mean nonstop rain from dawn to dusk. In fact, conditions vary depending on the region, month, elevation, and even the time of day. While one area may experience an afternoon shower, another could stay dry for hours.
So if you’re planning a hiking trip during this time of year, there’s no reason to put your plans on hold. This guide explains what to expect, how to prepare for changing conditions, and practical tips to help you enjoy your hike, rain or shine.

When Is the Rainy Season in Costa Rica?
Costa Rica’s rainy season —also known as the green season— generally runs from May through November across much of the country, though rainfall patterns aren’t the same everywhere. The Caribbean coast, for example, follows a different weather pattern and doesn’t always experience the same seasonal conditions as the rest of the country.
In many rainforest regions, mornings are often a practical time for hiking, as heavier showers are more common later in the day. Even so, this is a general pattern rather than a guarantee. Weather can change quickly, so it’s always worth checking local conditions before heading out.
7 Things that Change When Hiking in Costa Rica During the Rainy Season
Rain changes more than the scenery. It can affect trail conditions, what you pack, how long your hike takes, and what you see along the way.
Here are seven ways Costa Rica’s tropical weather can affect your hiking experience:
1. Trails May Be Wetter, Muddy, and More Slippery
Rain can make hiking trails wetter, muddier, and more slippery than usual. Soil, rocks, exposed roots, wooden walkways, bridges, and stairs may all become more difficult to walk on, especially after recent rainfall.
Not every trail is affected in the same way. Conditions depend on factors such as how much rain has fallen recently, the trail’s design and maintenance, elevation, drainage, terrain, and even the number of visitors using the trail.
Take your time, watch each step, and follow any trail closures or safety recommendations. Well-maintained trails often remain easy to follow, even in wet conditions, while more rugged or steep hikes may require extra caution and effort.
2. Your Hiking Shoes Matter More
Reliable traction becomes even more important during the rainy season. Wet soil, rocks, roots, and wooden surfaces can all become slippery, so choosing the right footwear helps you stay comfortable and confident on the trail.
For many hikes, hiking shoes, trail-running shoes, lightweight hiking boots, or sturdy sneakers with textured soles provide the grip you need. The best option depends on the trail, recent weather, and the level of support you prefer.
Avoid flip-flops, smooth-soled sneakers, or any footwear that becomes unstable when wet. Waterproof shoes can be helpful if you expect muddy trails or shallow puddles, while breathable shoes may feel cooler and dry more quickly in Costa Rica’s humid climate.

3. You’ll Need Better Rain Protection
A lightweight rain jacket or poncho is usually a better choice than a heavy waterproof coat. It helps keep you dry without adding unnecessary bulk or trapping too much heat and humidity while you hike.
Wear quick-drying clothes and bring a waterproof phone case or dry bag to protect your essentials. We recommend packing an extra pair of socks, a small towel, and a dry change of clothes for after your hike, especially if you plan to continue exploring.
While an umbrella may seem like a good idea, it can be awkward to use on narrow trails, in windy conditions, or while crossing hanging bridges. Lightweight rain gear leaves your hands free and is often the more practical option.

4. Visibility Can Change Quickly
Clouds, mist, and rain can reduce views of volcanoes, mountains, and distant scenery—sometimes within minutes. That doesn’t necessarily take away from the experience. Mist and low clouds give the rainforest a different look, but if a clear volcano view is your main goal, it’s worth staying flexible with your plans.
Check local conditions before you head out, but don’t rely entirely on the forecast. Mountain and rainforest weather can change quickly, and it’s worth remembering that views of Arenal Volcano are never guaranteed, even during the dry season.
5. Wildlife Activity May Feel Different
The rainy season means a change in how and when you notice wildlife. Extra moisture tends to bring frogs, insects, and other rainforest species out and about, making them easier to spot—while heavier rain can make some animals harder to see.
Birds and mammals may be more active just before or after a shower rather than during the heaviest rainfall itself. Even so, wildlife sightings always depend on timing, habitat, weather conditions, and a bit of luck.
At Mistico Park, visitors may notice more amphibian, insect, and other rainforest activity when added moisture reaches the forest.
6. Hikes May Take Longer Than Expected
Rainy-season hikes often take longer than you might expect. Mud, wet steps, photography stops, or simply waiting for a passing shower can all slow your pace, even on familiar or well-maintained trails.
When planning your day, leave extra time for:
- Parking and check-in
- Changing clothes
- Cleaning shoes
- Slower driving
- Rest breaks
- Delays between activities
A good rule of thumb is not to book another timed tour immediately after a rainy-season hike.
7. Some Trails or Tours May Be Affected
Light rain won’t cancel a hike on its own, but more severe weather can lead to trail closures, delays, or rescheduled tours.
Weather conditions that may affect a hike include:
- Strong winds
- Flooding
- High river levels
- Landslides
- Lightning
- Reduced visibility
- Unsafe bridge or trail conditions
At Mistico Park, tours continue as scheduled during normal wet weather. They are only delayed or rescheduled when conditions turn extreme, because safety always comes first.
If you plan to visit Costa Rica during the rainy season, always follow the guidance of park staff, guides, and official alerts rather than deciding conditions are safe on your own.
Hiking at Mistico Park During the Rainy Season
The rainy season offers a different way to experience the rainforest, and Mistico Park remains open during normal rainy conditions so you can enjoy the trails throughout much of the season.
Here’s what you can expect during your visit:
- Lush, vibrant vegetation
- Cooler walking conditions
- Wet hanging bridges and hiking trails
- Mist drifting through the rainforest
- Changing views of Arenal Volcano throughout the day
- Wildlife activity that may be more noticeable before or after rain
- Fewer crowds on some days
If you can, plan your visit earlier in the day and wear closed-toe shoes with good traction, especially after recent rainfall.
At Mistico Park, tours run as usual in normal rain. If the weather becomes extreme, they may be delayed or rescheduled to help keep everyone safe.

How to Decide Whether to Hike That Day
Weather can change quickly during the rainy season, so it’s always a good idea to take a few minutes to check conditions before you head out.
Use this quick checklist before your hike:
- Check the latest local weather forecast.
- Ask your hotel, guide, or the park about current trail conditions.
- Confirm that your tour is operating as scheduled.
- Consider the trail’s difficulty and recent weather.
- Think about your group’s hiking experience and mobility.
- Avoid hiking during lightning or other severe weather.
For the latest conditions in the Arenal area, check our La Fortuna weather forecast before your visit.
And if the weather doesn’t cooperate, that’s okay too. Sometimes the best way to experience the rainforest is to slow down, find a covered spot, and simply watch the rain fall until it’s time to head back outside.
Is Hiking in Costa Rica’s Rainy Season Worth It?
Rainforest trail with lush vegetation and flowing streams during Costa Rica’s rainy season.
Yes—if you’re comfortable with changing weather and willing to adjust your plans, hiking during the rainy season can be a rewarding experience. The rainforest is at its greenest, temperatures are often cooler, waterfalls and rivers are flowing, and some trails may have fewer visitors than during the drier months. You may also notice different wildlife activity and see the forest in a completely different light.
That said, the rainy season also comes with muddy trails, changing visibility, and the possibility of weather-related delays. If you come prepared, stay flexible, and follow local guidance, the rainy season can be one of the most memorable times to explore Costa Rica’s rainforests.
Book a Rainy-Season Rainforest Walk at Mistico Park
Even when the weather turns wet, Mistico Park is a great place to experience Costa Rica’s rainforest. Explore well-maintained trails, cross hanging bridges, and choose between a guided or self-guided visit through one of La Fortuna’s most biodiverse rainforests.
