10 Best Costa Rica Activities for Nature Lovers

Why Costa Rica Works for Nature and Outdoor Travel

Hike to jungle waterfalls, soak in volcanic hot springs, raft a river gorge, or spot sloths, toucans, and scarlet macaws on a guided rainforest walk. Outdoor activities in Costa Rica pack an unusual amount of variety into a small country, often within a single week of travel. 

That variety comes from the landscape. Costa Rica covers about 0.03 percent of the earth’s surface yet holds an estimated 5 to 6 percent of its known species. They are spread across rainforest, cloud forest, volcanic highlands, and two coastlines a few hours’ drive apart. Roughly a quarter of the country lies inside national parks, wildlife refuges, and reserves, the result of decades of national policy that put conservation ahead of unchecked development.

The climate keeps trails and rivers open year-round. On the Pacific side, the dry season (December to April) brings the most dependable hiking and wildlife-viewing weather. The green season (May to November) means fewer people, lower rates, and higher rivers for rafting. The Caribbean coast follows its own rainfall pattern, so timing depends on where you’re headed. Our guide to the best time to visit Costa Rica breaks it down by region and month. The 10 experiences below are grouped roughly by region, so you can see which ones fit together on a single trip.

1. Walk Arenal’s Lava Fields and Soak in Hot Springs

Arenal Volcano rises in a near-symmetrical cone above the rainforest of Arenal Volcano National Park. It erupted almost continuously from 1968 until 2010 and has been quiet since. Today you can walk trails across hardened lava, including flows from a 1992 eruption, with the cone in view for much of the way. Adventure Life plans your day around a local guide who knows the trail system and when the summit is most likely to be clear. Hanging-bridge walks in the surrounding forest add a view from canopy level. Many travelers end the day in natural hot springs warmed by the area’s geothermal activity. Arenal also pairs easily with a rafting day or a zip-line canopy tour if you want a faster pace.

2. Hike Down to La Fortuna Waterfall

A short drive from Arenal, La Fortuna Waterfall drops roughly 230 feet (about 70 meters) into a pool ringed by rainforest. Reaching the base means a stairway of around 500 steps down and the same climb back up, with rest stops along the way. The current directly under the falls is strong, so most people swim in the calmer water a little downstream. Adventure Life often schedules the visit early in the day, when the trail is cooler and less crowded. It fits easily into an Arenal stay as a half-day outing.

3. Walk Suspension Bridges Through Monteverde’s Cloud Forest

The Monteverde Cloud Forest Reserve feels very different from the lowland rainforest: cooler, often misty, and thick with mosses, orchids, and ferns. Trails and suspension bridges cross several layers of the forest on foot. A sky tram or zip-line circuit covers similar ground for those who would rather ride. The reserve protects more than 400 bird species, including the resplendent quetzal, which is far easier to find with a local naturalist who knows where it tends to feed. Adventure Life can build guided time into your Monteverde days for that reason.

4. Hike Past Mud Pots and Hot Springs at Rincón de la Vieja

In Guanacaste, Costa Rica’s drier northwest, Rincón de la Vieja National Park surrounds an active volcano. Marked trails connect bubbling mud pots, steam vents, and hot springs. The park offers volcanic scenery without the long transfers that remote parks like Corcovado require, and it pairs well with a few days on the Guanacaste coast. A common route combines Arenal, a day at Rincón de la Vieja, and a beach stay at Playa Panamá. Adventure Life matches the trail to your fitness level and handles timing and transportation. 

5. Spot Wildlife on the Trails to Manuel Antonio’s Beaches

Manuel Antonio National Park combines two things that rarely overlap: reliable wildlife sightings and swimmable beaches, connected by short rainforest trails. Sloths, white-faced capuchins, and squirrel monkeys are common along the main paths. The paths lead to coves with calm, shallow water, which makes the park a good fit for families with younger children. Park hours and entry rules are tightly regulated and change from time to time. Adventure Life tracks the current schedule and builds your guide and transportation into the itinerary.

6. Track Wildlife in Corcovado National Park

Entry to Corcovado National Park requires a certified guide and an advance permit, rules in place since 2014. Adventure Life arranges both, along with the flight from San José to Puerto Jiménez and the overland trip to your lodge at the park’s edge. Lodging options there include La Leona EcoLodge, a tented camp reached partly on foot along the beach. Corcovado takes up a large share of the Osa Peninsula. Its rainforest supports wildlife that is hard to see elsewhere in the country: tapirs, anteaters, scarlet macaws, and five of Central America’s six wild cat species, including the jaguar, though sightings of the cats take real luck. Expect heat, humidity, and long walks.

7. Raft the Pacuare River

The Pacuare River cuts through forested canyons on Costa Rica’s Caribbean slope. The classic run is mostly Class III, with several Class IV drops in the gorge. Water levels follow the rain. In the dry months, the bigger rapids tend to soften. September and October usually bring the highest, fastest water, and outfitters may reschedule a trip if levels spike.
Adventure Life includes the Pacuare on many active itineraries, often alongside a two-day climb of Chirripó, sea kayaking in Ballena National Park, or time on the Osa Peninsula. Some trips spend two days on the river, with a night at a riverside lodge. If you’d like something gentler, the Class II–III Savegre near Manuel Antonio is a good fit for families and first-time rafters.

8. Cruise Tortuguero’s Canals and Watch Sea Turtles Nest

Tortuguero National Park, on the northern Caribbean coast, is reached only by boat or small plane, and that isolation keeps much of its wildlife close to the waterways. Guided boat tours move slowly through the canals, where monkeys, caimans, and many bird species are regular sightings. The park’s beach is a nesting site of global importance for green sea turtles. Their season runs roughly July through October, with the heaviest nesting in July and August. Leatherbacks nest earlier in the year, beginning around March. Night turtle walks require a registered guide during nesting season. Adventure Life arranges your boat transfers, lodge, and guided tours together.

9. Snorkel the Reef at Cahuita National Park

Cahuita National Park was created in 1970 to protect a coral reef just off Costa Rica’s southern Caribbean coast. A flat coastal trail runs between beach and forest, and sloths, howler monkeys, and coatis are common sightings along the way. Snorkeling on the reef requires a certified guide, and most trips reach it by boat, so a morning hike and an afternoon snorkel fit easily into one day. No dive certification is needed. Water clarity changes with rainfall and runoff, so Adventure Life plans around current conditions and arranges your guide and gear in advance.

10. Surf and Take In Caribbean Beach Culture in Puerto Viejo

A short drive south of Cahuita, Puerto Viejo is the main town on Costa Rica’s southern Caribbean coast. Its Afro-Caribbean roots show in the food, the music, and the easygoing pace. Nearby beaches such as Playa Cocles and Playa Chiquita range from gentler waves suited to lessons to faster, more powerful breaks for experienced surfers. Adventure Life can arrange lessons or board rentals in advance. The town also works well as a base for Cahuita and for days spent more on the beach than on the trail.

Plan Your Costa Rica Nature Trip

Every Costa Rica itinerary we build starts with what you want to do, not a fixed template. Add a coffee farm tour, a cultural village visit, or extra time in the rainforest, and drop anything that doesn’t fit. Costa Rica has enough rainforest, coastline, and wildlife to support dozens of different trips, which is why a trip planner who knows the country firsthand is more useful than a fixed package. Tell us what matters most to you, and we’ll build the route around it.
