If you are currently contemplating a visit to this island, rest assured that this write-up will provide you with comprehensive information about Caño Island Biological Reserve on a silver platter.

Let’s embark on a journey through the captivating Isla del Cano, exploring its rich history, uncovering its hidden treasures, and discovering the allure that awaits you on this remarkable island.
Isla del Caño is situated in the province of Puntarenas, Costa Rica, near the Osa Peninsula. It is believed to have formed approximately 40-50 million years ago as a result of tectonic plate movements. During these geological processes, the Caribbean Plate moved over the Cocos Plate, giving rise to this small yet incredibly unique island. With a total area of only 3.26 km², its highest point reaches 123 meters above sea level. The island’s shoreline features a mix of rocky areas and sandy beaches. One of these beaches serves as a checkpoint for park rangers who ensure the island’s safety.
The underwater realm surrounding Isla del Caño is also part of the protected area. Exploring the island’s waters is a true delight, as it encompasses an expansive area of 5,800 hectares. These waters boast some of the most diverse and well-preserved coral reef formations along Costa Rica’s Pacific coast. Additionally, there are five distinct coral platforms in the vicinity. Regrettably, the coral around the island suffered significant damage in 1982-83 due to the warming of ocean waters caused by the influence of the “El Niño” ocean current.

Isla del Caño was officially “discovered” in 1519 by Captain Juan de Castañeda during his exploration of the Nicoya Bay area. For archaeologists, the island holds special significance as it provides valuable evidence of Costa Rica’s history. Numerous artifacts indicating human presence in pre-Columbian times have been unearthed on the island. Archaeological studies have revealed the existence of a cemetery on the island dating back to the 700s and 1500s BC. However, the most intriguing discoveries are the enigmatic stone spheres, which have become an iconic part of Costa Rican history.
These stone spheres, made from stone with remarkably precise shapes, reach diameters of up to 2.5 meters. The mystery surrounding them lies in the unanswered questions of their purpose and the methods used to create them. Despite numerous hypotheses, we still lack definitive answers. Adding to the enigma, these multi-ton stone spheres were transported from the mainland—a task that even with modern tools and equipment would be challenging. How our ancestors accomplished this feat with primitive tools and wooden boats remains a captivating puzzle.
Additionally, Isla del Caño served as a trading post for ships passing through the region. Excavations have uncovered remnants of pottery and intricately carved stone artifacts, leading archaeologists to believe that indigenous cultures utilized the island as a crucial trading hub along the Pacific coast.
The island of Isla del Caño is predominantly covered with tropical forests, as well as secondary stands of various ages. Within the park, a total of 158 different plant species have been identified, offering a rich and diverse botanical landscape. Among these species, you can encounter a variety of trees such as banana trees, orange trees, mango trees, as well as lush ferns that contribute to the island’s verdant beauty.
Isla del Caño is home to impressive trees that can reach heights of up to 50 meters. Among the fascinating tree species found on the island is the milk tree, also known as “palo de vaca” in Spanish. This tree derives its name from the white sap obtained from it, which resembles milk. The sap, often referred to as milkweed, was historically used by indigenous communities in Central and South America as a substitute for cow’s milk. It is worth noting that the sap contains around 7% protein, making it a potential food source.
What’s interesting is that the taste of the sap can vary, ranging from sweet to bitter. In addition to the milk tree, Isla del Caño boasts other distinctive plant species, including orchids, wild cacao, and figs. These diverse flora contribute to the island’s natural beauty and ecological richness.
While the fauna on the island may not be as abundant as in some other regions, the island is still home to several interesting species. Among the wildlife you may encounter on the island are boa snakes, foxes, frigatebirds, bats, frogs, and eagles. These diverse creatures contribute to the ecological balance of the island’s ecosystem.
In the coastal waters surrounding Isla del Caño, you can find the impressive Mahi-Mahi fish, also known as Dorado. These fish are known for their vibrant colors and acrobatic displays. They are a popular catch for sport fishermen in the area. Additionally, angelfish are another notable species found in the waters near the island. With their striking appearance and graceful movements, they add beauty to the marine environment. While the fauna may not be as extensive as on the mainland, the presence of these unique species adds to the allure and biodiversity of this Biological Reserve.
The natural beauty and cultural heritage of Isla del Caño faced a serious threat in the 1970s when the Costa Rican government leased the entire island to a private company with the intention of creating an exclusive resort. This plan raised concerns among conservationists and biologists who recognized the ecological value of the island.
In response, the Costa Rican Association of Biologists launched a campaign to prevent construction on the island and protect its natural resources. Their efforts were successful, leading to the incorporation of Isla del Caño into Corcovado National Park in 1976. Two years later, the Cano Island Biological Reserve was established as a separate protected area.
Thanks to the actions taken by the conservationists, the plans for a resort were halted, and the island was preserved for its ecological significance and cultural heritage. Today, Caño Island Biological Reserve remains a protected area, allowing visitors to appreciate its pristine natural environment and explore its archaeological wonders, free from the impacts of commercial development.
Isla del Caño, located on the Pacific coast of Costa Rica, experiences two distinct seasons. The dry and warm season begins in December and extends until April. This period attracts the most tourist activity and offers optimal conditions for diving. The weather is generally dry, and temperatures are warm, creating a favorable environment for outdoor activities. From May onwards, the rainy season sets in and continues through the fall. However, it’s important to note that this doesn’t imply continuous rainfall. Many travelers actually consider the rainy season to be a great time to visit Costa Rica. The temperatures are slightly cooler, and the frequent rain showers contribute to lush vegetation growth.
The national parks, including Isla del Caño, transform into vibrant green landscapes during this time, resembling an “ocean of green.” While underwater visibility may decrease slightly during the rainy season, diving and snorkeling can still be highly enjoyable. Additionally, September marks the arrival of whales in Costa Rica as they undertake their annual migration. This presents a wonderful opportunity to witness these majestic creatures in their natural habitat.
Whether you choose to visit during the dry season for optimal diving conditions or during the rainy season to experience the lush beauty of Costa Rica, Isla del Caño offers captivating natural wonders and memorable experiences throughout the year.

My life has always been linked to sports commonly considered extreme. I once fell in love with big wall climbing, just as I am now in love with scuba diving. I climbed mountains, explored caves and took part in exploration expeditions. Through these experiences, I saw a large chunk of the world and learned a lot. Now I have been a professional diver and a scuba instructor for many years, and Costa Rica has become my second home. Check also my expedition project: @goexplorewith.me
