Over a quarter of Costa Rica’s landscape is protected by its comprehensive system of national parks, wildlife refuges and biological reserves.

As well as being crammed with stunning landscapes and startling biodiversity, these parks and reserves contain some truly memorable hikes, which may take you deep into verdant rainforest, past bubbling mud pools or along surf-lashed beaches.

It can be hard to narrow down the choices, so we’ve selected a few of our favourites to help you decide.

1. Volcán Poás, Parque Nacional Volcán Poás

Standing proud in the centre of the park, Poás is one of the world’s more easily accessible active volcanoes – you can reach it by public transport from San José and Alajuela – with an eleven-million-year history of eruptions.

You can take your pick from the very well-maintained, short and unchallenging trails which weave through the park’s unusual dwarf cloudforest. The Crater Overlook Trail, which winds around the main crater along a paved road, is only 750m long and is accessible to wheelchairs and pushchairs.

2. Sendero Los Patos-Sirena, Parque Nacional Corcovado

This tough 20km trek through dense rainforest (allow 9 hours) gives experienced hikers the chance to spot some of Costa Rica’s more elusive large mammals, such as the tapir and collared peccary. The Los Patos-Sirena route starts near the village of Rincón de Osa, which runs a programme to train locals as naturalist guides.

Everyone trekking in Corcovado must be accompanied by a guide, and they tend to enrich your experience; the guides at Rincón are taught to identify some of the approximately 370 species of bird recorded in the area, not to mention the amphibians, reptiles, insects, mammals and plants. Ask in Rincón or at the Oficina de Área de Conservación Osa in Puerto Jiménez for details.

3. Cerro Chirripó, Parque Nacional Chirripó

The multi-day hike up Costa Rica’s highest peak – 3820m (12,533ft) – is a long but varied ascent through cloudforest and paramo to rocky mountaintop; on a clear morning, you can see right across to the Pacific.

The services of a guide can be both useful and illuminating, as they’ll be able to help you identify local species and interpret the landscapes you pass through; ask at the ranger station at the entrance for recommendations.

4. Reserva Rara Avis

Costa Rica’s premier ecotourism destination flourishes with primitive ferns and has more kinds of plants, birds and butterflies than the whole of Europe; 367 species of bird alone have been identified here. The wonderfully remote, wildlife-rich Reserva Rara Avis has a 30km network of excellent trails, which are well marked and offer walks of thirty minutes to several hours.

Given the effort it takes to reach the reserve, it’s worth staying for a couple of nights and exploring. The informative guided walks are a great opportunity for spotting some of the reserve’s abundant wildlife; night walks are also possible, and show you a different side of the rainforest.

5. Estación Biológica Pocosol, Monteverde

This two-day trek from Monteverde to the research station on the eastern edge of the Bosque Eterno de los Niños, Costa Rica’s largest private reserve, is arguably the most adventurous hike in the country.

It’s real bushwhacking stuff, on unmarked trails (pumas have been spotted around the refuge where you spend the night), and you must be escorted by two fully equipped, armed rangers trained in first aid.

6. Sendero Laguna Meándrica, Parque Nacional Carara

This 4.3km round trip (allow 2–4 hours) is perhaps the finest birding trail of any national park in the country – and that’s saying something. It winds through the western half of the park to a croc-filled oxbow lake, home to myriad bird species.

In particular, Carara is one of Costa Rica’s best spots to see the scarlet macaw in its natural habitat – they migrate at dawn and dusk between the lowland forest areas and swampy mangroves, soaring overhead in a burst of red and blue. It’s worth hiring a guide from the visitor centre, 2km south of the trail entrance, as there are some areas visitors can’t access when unaccompanied.

7. Sendero Las Pailas, Parque Nacional Rincón de la Vieja

This terrific 6km circuit takes in the best of this memorable national park in the shadow of a smoking volcano. The trail is not too demanding and has recently been updated with smooth concrete pathways and a wheelchair-accessible section.

It heads past many of the unusual natural features with which the park abounds, including mud pots (pilas de barro) and geothermal hornillas (literally, “stoves”), mystical-looking holes in the ground exhaling elegant puffs of steam. Make sure not to go nearer than a metre or so, though, or you’ll be steamed in no time. The trail also takes you through forest with abundant fauna and flora, and you should be prepared to ford a couple of streams.
