When to visit

Seasonal Breakdown

The Desventuradas Islands, located off the coast of Chile, experience a maritime climate with mild temperatures year-round. The islands are remote and largely uninhabited, with weather patterns influenced by the Humboldt Current. Seasons are less pronounced than on the mainland, but distinct periods can still be identified.

Summer (December – February)

Summer brings the warmest temperatures, averaging between 15°C to 20°C (59°F to 68°F), with relatively calm seas and minimal rainfall. This is the peak season for scientific expeditions and limited tourism due to accessibility. Pros include the best weather for marine activities like diving and wildlife observation. Cons involve potential logistical challenges, as the islands are rarely visited and lack infrastructure.

Autumn (March – May)

Temperatures begin to cool slightly, ranging from 12°C to 17°C (54°F to 63°F), with increasing cloud cover and occasional rain. Wildlife remains active, making it a quieter alternative to summer. However, sea conditions can become rougher, limiting boat access.

Winter (June – August)

Winter is the coolest and wettest season, with temperatures between 10°C to 14°C (50°F to 57°F) and higher humidity. Storms are more frequent, making travel to the islands nearly impossible. This period is not recommended for visitors due to harsh conditions.

Spring (September – November)

Spring sees a gradual warming, with temperatures rising to 13°C to 18°C (55°F to 64°F) and reduced rainfall. The seas begin to calm, and wildlife activity increases, offering opportunities for birdwatching and marine life sightings. This is an ideal time for those seeking solitude and nature.

Overall Recommendation

The best time to visit the Desventuradas Islands is during the summer months (December – February), when weather and sea conditions are most favorable for exploration. However, travelers should be prepared for limited access and logistical challenges. For those preferring fewer disturbances, spring (September – November) offers a quieter alternative with improving conditions.

Considerations

The islands have no tourist infrastructure, and visits are typically restricted to scientific or specialized expeditions. There are no peak tourist seasons or festivals, but weather and sea conditions dictate accessibility. Travelers must plan well in advance and coordinate with authorized operators.

What to Pack for Desventuradas Islands

The Desventuradas Islands, a remote Chilean archipelago, are known for their rugged terrain, marine biodiversity, and unpredictable weather. Packing smartly ensures you're prepared for the islands' unique challenges.

Outdoor & Adventure Gear

  • Sturdy waterproof hiking boots: Essential for navigating rocky, uneven terrain and occasional wet conditions.
  • Quick-dry layers & windproof jacket: The islands can be windy and damp, so moisture-wicking clothing is key.
  • Compact binoculars: Ideal for spotting seabirds, marine life, and distant landscapes.
  • Dry bags or waterproof cases: Protect electronics and essentials from salt spray and rain.

Marine & Coastal Essentials

  • Reef-safe sunscreen & lip balm: Harsh sun and wind can cause rapid dehydration and sunburn.

  • Water shoes or neoprene booties: Protect feet from sharp rocks and coral while exploring tide pools.

Logistical Must-Haves

  • Portable water filter or purification tablets: Freshwater sources may be limited or unreliable.
  • High-calorie snacks & electrolyte packs: Remote location means limited access to supplies.
  • Satellite communicator or emergency beacon: Cell service is nonexistent; safety is critical.

Getting there

By Air

The Desventuradas Islands are remote and uninhabited, with no airports or airstrips. The nearest major international airport is Arturo Merino BenĂ­tez International Airport (SCL) in Santiago, Chile. From there, travelers must arrange specialized transportation, typically by naval vessel or private charter, as the islands are only accessible via the Chilean Navy or scientific expeditions. No commercial flights or regular air services operate to the islands.

By Sea

The primary way to reach the Desventuradas Islands is by sea, usually through organized expeditions or naval operations. The islands lie approximately 850 km off the coast of Chile, and access is highly restricted due to their status as a protected nature reserve. Key considerations:

  • Naval or Research Vessels: The Chilean Navy occasionally conducts patrols or supports scientific missions to the islands. Permission must be secured in advance.
  • Private Charters: Limited private charters may be arranged from mainland Chile, but these are rare and require extensive planning.
  • Departure Points: Most voyages originate from ValparaĂ­so or other major Chilean ports, with travel times varying based on weather and vessel type.

Practical Advice

Due to the extreme remoteness and restricted access, visiting the Desventuradas Islands is challenging and typically reserved for researchers or authorized personnel. Travelers should:

  • Contact Chilean authorities or research institutions well in advance to inquire about access permissions.
  • Prepare for extended sea travel with limited amenities, as the journey can take several days.
  • Monitor weather conditions, as rough seas can delay or cancel voyages.

Getting around

Getting Around Desventuradas Islands

The Desventuradas Islands, a remote and uninhabited archipelago off the coast of Chile, offer a unique but challenging travel experience. Due to their isolation and lack of infrastructure, transportation options within the province are extremely limited. Here’s what you need to know:

Boat Travel

The primary way to explore the Desventuradas Islands is by boat, as there are no roads, airports, or public transportation systems. Most visitors arrive via private or chartered vessels, often as part of scientific expeditions or eco-tourism adventures.

  • Chartered Boats: The only practical way to navigate between islands (San FĂ©lix and San Ambrosio) or along the coastlines. These are typically arranged through specialized tour operators or research organizations.
  • Cost: Expensive, as charters must be arranged well in advance from mainland Chile. Prices vary depending on the duration and purpose of the trip.
  • Tips: Ensure your boat is equipped for rough seas, as the waters around the islands can be treacherous. Pack all necessary supplies, as there are no facilities on the islands.

On-Foot Exploration

Once on the islands, travel is exclusively on foot. There are no marked trails or infrastructure, so exploration requires careful planning and self-sufficiency.

  • Terrain: Rugged and volcanic, with steep cliffs and limited flat areas. Sturdy footwear and caution are essential.
  • Wildlife: The islands are home to unique ecosystems, so stick to designated areas (if any) to minimize environmental impact.

Practical Advice

Given the extreme remoteness of the Desventuradas Islands, visitors must be entirely self-reliant. Here are key considerations:

  • Permits: Access to the islands is restricted. Secure permission from Chilean authorities or join an organized expedition.
  • Supplies: Bring all food, water, and medical supplies, as there are no services available.
  • Weather: Conditions can change rapidly. Monitor forecasts and plan accordingly.

Culture

Isolation and Maritime Heritage

The Desventuradas Islands, comprising San Ambrosio and San Félix, are among the most remote and uninhabited territories of Chile. Their cultural identity is deeply tied to their isolation and maritime history. The islands have no permanent population, but their waters have been frequented by Chilean fishermen and naval personnel, who have contributed to a unique, transient maritime culture. Stories of shipwrecks, endurance, and the harsh Pacific environment are woven into local lore.

Environmental Stewardship

Due to their ecological significance, the islands are protected as part of the Desventuradas Marine Park. The cultural ethos here emphasizes conservation, with Chilean scientists and naval crews fostering a deep respect for the fragile ecosystem. Visitors—though rare—are expected to adhere to strict environmental protocols, reflecting the islands' role as a natural sanctuary.

Transient Traditions

While the islands lack permanent residents, temporary inhabitants—such as researchers and fishermen—have developed informal traditions. These include shared meals of freshly caught fish, storytelling under the stars, and improvised celebrations marking milestones like successful research expeditions or naval deployments. The camaraderie among these transient communities highlights resilience and adaptability.

Historical Legacy

The islands' name ("Unfortunate" in Spanish) dates back to 16th-century Spanish explorers who found them inhospitable. This history is preserved in naval records and occasional commemorative visits by the Chilean Navy, which underscore the islands' strategic and symbolic importance to Chile's maritime sovereignty.

Visitor Etiquette

  • Respect conservation rules: Strict no-take policies apply to flora, fauna, and marine life.
  • Minimal impact: Leave no trace of your visit; even temporary stays are closely monitored.
  • Cultural sensitivity: Acknowledge the islands' role as a scientific and naval outpost rather than a tourist destination.
