Overview
Túquerres is a small municipal town in the Nariño department of southwestern Colombia, sitting at roughly 3,000 metres above sea level on the Andean plateau. It serves as the main gateway to Azufral Volcano and is itself a quiet, authentic Colombian highland town with a functioning weekly market and a strong indigenous Pasto heritage.
Azufral Volcano (also written El Azufral) rises to approximately 4,070 metres and is best known for the strikingly coloured Laguna Verde — a crater lake whose waters shift between emerald green, turquoise, and grey depending on the light, weather, and volcanic chemistry. The colour comes from dissolved sulphur and other minerals, giving the lake an otherworldly appearance that draws hikers and nature travellers from across Colombia and beyond.
The surrounding landscape is classic high-Andean páramo: boggy grasslands, frailejón plants (Espeletia), mist, and an almost complete absence of trees. Wildlife in the páramo includes Andean condors (occasionally spotted), deer, and a range of high-altitude bird species. The combination of volcanic geology, extreme altitude, and botanical rarity makes Azufral one of the more compelling natural destinations in Nariño.
Before You Go
Altitude and Acclimatisation
Both Túquerres and the trail to Laguna Verde sit at high altitude. Visitors arriving from sea-level cities such as Bogotá or the coast should allow at least one full day to acclimatise before attempting the volcano hike. Symptoms of altitude sickness (headache, nausea, shortness of breath) are common; ascend slowly and stay well hydrated. If symptoms are severe, descend and seek medical attention.
Fitness Level
The hike to Laguna Verde is moderately demanding. The trail is not technical, but the altitude and sometimes muddy, uneven terrain require reasonable fitness and sturdy waterproof footwear. Trekking poles are helpful.
Weather Preparedness
Conditions at the crater can change rapidly. Even on a sunny morning, cold fog and rain can arrive within minutes. Pack waterproof outer layers, warm mid-layers, a hat, gloves, and sunscreen. Sun intensity at altitude is deceptively strong even in cloud cover.
Visas
For entry requirements into Colombia, check TravelerPulse's Visas section and consult Migración Colombia's official website for current rules applicable to your nationality.
What to Bring
- Waterproof jacket and warm layers
- Sturdy hiking boots (waterproof preferred)
- Trekking poles (optional but useful)
- Water and snacks for the day
- Cash in Colombian pesos (ATM availability in Túquerres is limited; verify locally)
Getting There
From Pasto
Túquerres is located approximately 70 km west of Pasto, the departmental capital of Nariño. Shared minibuses (colectivos) run regularly between Pasto's bus terminal and Túquerres throughout the day; journey time is roughly 1.5 to 2 hours depending on road and traffic conditions. Verify current schedules and fares at the terminal on arrival.
From Ipiales
Ipiales (near the Ecuador border) is roughly 50–60 km south of Túquerres. Colectivos also connect these two towns; journey times and schedules should be confirmed locally.
By Air
The nearest airports with regular domestic service are Antonio Nariño Airport (serving Pasto) and El Edén International Airport in Armenia. From either, you would continue overland. Verify airline schedules and routes before booking, as Andean weather frequently affects small regional airports.
Getting to Azufral Volcano
From Túquerres, the trailhead for Azufral is reached by road to the village of Cuaical or a nearby access point (verify the current trailhead location locally, as access routes can change). Local transport or hired vehicles cover this section. The hike from the trailhead to Laguna Verde takes approximately 2–3 hours one way. Guided tours departing from Túquerres are available and recommended for first-time visitors.
Getting Around
Túquerres itself is a compact town navigable on foot. Mototaxis operate within the town and to surrounding villages for short trips; agree on the fare before boarding.
For Azufral, the most practical approach is to hire a local guide or join an organised day tour departing from Túquerres. Local guides are familiar with trail conditions, weather patterns, and the entry process. Prices and guide availability should be verified locally or through Nariño-based tour operators in Pasto.
There is no significant public transport specifically timed for the Azufral hike, so independent travellers typically rely on a hired vehicle to reach the trailhead and arrange return transport in advance.
Things to See & Do
Hike to Laguna Verde, Azufral Volcano
The centrepiece experience of the area. The crater lake's colour and the surrounding páramo make this one of the most visually distinctive hikes in southwestern Colombia. Start early — ideally before 7 a.m. — to maximise chances of clear conditions at the summit. Cloud cover typically builds through the afternoon.
Explore Túquerres Town
The town has a traditional Saturday market where local Pasto and Quillacinga communities trade produce, textiles, and crafts. The central plaza and church are modest but reflect the colonial and indigenous layering of the region. Walking the market is a genuine, uncommericalised experience.
Birdwatching in the Páramo
The high-Andean ecosystem around Azufral supports specialist páramo birds. Species such as the Andean condor (occasional sightings), hummingbirds adapted to altitude, and various tanagers and seedsnipes have been recorded in the area. Bring binoculars and, if serious about birding, arrange a specialist guide through a Pasto-based operator.
Visit Surrounding Lagoons
The broader Azufral area reportedly contains additional smaller lagoons and volcanic features; local guides can advise on what is currently accessible and safe to visit.
Observe Frailejón Ecology
The páramo frailejones (Espeletia spp.) are remarkable plants, some hundreds of years old, adapted to harvest water from clouds. Walking slowly through a frailejón field and understanding this ecosystem is itself a worthwhile activity for nature-oriented travellers.
Food & Drink
Túquerres has a small selection of local restaurants (fondas and comedores) around the central plaza and market area. Expect hearty Nariñense highland cooking: dishes commonly include cuy (guinea pig, a regional staple), sopa de maíz, fritada (fried pork), and papas chorreadas (potatoes in a cheese and tomato sauce). Mazamorra and colada are common breakfast or snack options.
Drinking water from taps is not recommended; bottled or filtered water is the safe choice. Hot drinks — tinto (black coffee), agua de panela (hot sugarcane water), and herbal teas — are widely available and help with warmth and mild altitude adjustment.
Restaurant options in Túquerres are basic and practical rather than varied. Those with specific dietary requirements (vegetarian, vegan, gluten-free) should be prepared to self-cater in part or communicate clearly with restaurant staff; the local cuisine is strongly meat-based. Stock up on snacks in Pasto or at the Túquerres market before heading to Azufral, as there are no food services on the trail.
Practical Information
Money
Bring sufficient cash in Colombian pesos before arriving in Túquerres. ATM availability in town is limited and reliability cannot be guaranteed; verify locally. Pasto has more banking infrastructure and is a better place to withdraw cash before travelling to Túquerres.
Connectivity
Mobile coverage in Túquerres is functional with major Colombian networks, but degrades significantly on the trail to Azufral. Do not rely on your phone for navigation on the volcano; carry a physical map or hire a guide.
Medical
Túquerres has a basic health centre (verify current services locally). For anything serious, Pasto is the nearest city with hospital facilities. Carry a personal first-aid kit including blister care, pain relief, and any prescription medication you need.
Entry to Azufral
Azufral is managed as a protected natural area. Entry fees and permit requirements should be verified locally or through Parques Nacionales Naturales de Colombia or the relevant regional environmental authority (Corponariño), as these can change.
Emergency Numbers
Emergency services in Colombia: general emergency line 123. Verify local police and health contacts on arrival in Túquerres.
Safety
Túquerres is a small, generally calm highland town. The main safety considerations in the area are environmental rather than security-related.
The Azufral hike carries natural hazards: altitude sickness, rapidly changing weather, cold and wet trail conditions, and volcanic gases (sulphur) near the crater. Do not approach the crater rim in poor visibility or if volcanic activity warnings are in place. Check with local guides and regional civil defence (Defensa Civil) authorities for any current activity alerts before hiking.
Travel after dark on rural roads is inadvisable. Plan your return from Azufral to arrive back in Túquerres before nightfall. As in all rural Colombia, avoid displaying expensive equipment conspicuously and keep documents secure.
For current national-level safety context and travel advisories, consult your country's foreign affairs or travel advisory service before your trip.
Local Culture & Etiquette
Nariño department, including the Túquerres area, has a deep indigenous heritage rooted in the Pasto and Quillacinga peoples, who inhabited the high plateau before and through the Spanish colonial period. This heritage is visible in local markets, textiles, and some community traditions, though it is subtly expressed rather than heavily staged for tourism.
The department of Nariño is also known for its artisanal traditions, including the production of Barniz de Pasto (a distinctive lacquerwork technique using a resin from the mopa-mopa plant), though this craft is more centred in Pasto city itself.
Behave respectfully in and around the market and community spaces. Photography of people should always be done with permission. The area sees relatively few international tourists, so local interactions tend to be genuinely curious and hospitable rather than commerce-driven.
