Key Dive Site Facts
Dive Site Overview
Descend into a historical narrative at Las Calderas, exploring the skeletal remains of an early 20th-century steamer. Named for three prominent boilers, or 'calderas,' these features are clearly visible amongst the debris.
Wreck components are not consolidated; instead, they lie scattered over a considerable area, creating a dynamic environment for investigation. Divers trace the ship's history by navigating through its dispersed superstructure parts, experiencing a wide field of debris. Exploration reveals sections ranging from 5 to 23 m (16-75 ft), accommodating various certification levels.
Below, a diverse underwater topography awaits, featuring individual ship parts, natural rock corridors, and sandy expanses. Such varied conditions ensure both novice and experienced divers find engaging routes and features.
Expect distinct wall areas, a sandy bottom, and intricate rock formations, providing different exploration patterns. Marine life frequently seeks shelter within the numerous crevices and hidden corners of the scattered wreck, inviting closer inspection. Navigating these varied structures provides continuous interest.
Best Time to Dive
Diving conditions at Las Calderas typically show seasonal variations, offering prime opportunities from late spring through early autumn, then again in late autumn. Months like May through September often present the most favorable conditions, with average air temperatures ranging from 19.1°C (66°F) to 25.7°C (78°F). During this period, rainfall is minimal, often less than 1mm, and wave heights generally remain below 1 meter, contributing to better visibility and calmer seas. In contrast, early spring months like January to March, while still moderate, see higher average wave heights around 1.8-1.9 m (6-6.2 ft) and air temperatures in the 13-14°C (55-57°F) range, alongside slightly increased rainfall. Late autumn, particularly November and December, improves again with good dive scores, albeit with cooler air temperatures of 13-16°C (55-61°F) and moderate rainfall.

Dive Experience & Conditions
As you begin your descent at Las Calderas, the initial view often reveals a sandy seafloor transitioning into rugged rocky formations. The prominent boilers, which give the site its name, emerge first, signaling the core of the wreck site. Divers then explore the surrounding, rather deteriorated remains of the early 20th-century steamboat, scattered across a wide area. The varied underwater configuration includes distinct wall areas, sandy bottoms, and natural rock corridors that allow for different routes and extended exploration. Maximum depth reaches around 23 m (75 ft), but divers can find engaging features and marine life across shallower sections, too. The site's diverse structure supports various exploration patterns, whether focusing on the wreck itself or the adjacent geological formations.
Dive Difficulty & Safety Guidelines
Navigating the scattered debris field of Las Calderas requires careful buoyancy control and awareness, especially around the older, deteriorating wreck components. While the site accommodates various skill levels, the nature of a dispersed wreck means attention to potential entanglement points is prudent. Given that some local dive points in this Atlantic zone may not have a Natural Park buoy, dive operators often use their boat's anchor. This mandates precise boat handling and clear communication between the dive master and divers. Always maintain appropriate distances from the wreck structure to prevent disturbing sediment or encountering sharp edges.

Recommended Dive Suit
In these water temperatures, 5-7mm wetsuit is a common choice for recreational diving. Consider warmer surface protection (like a boat coat) due to brisk winds. A thermal robe or jacket is recommended between dives. Longer dive profiles can make thermal protection more important than short exploratory dives.

Marine Life at Las Calderas
The underwater landscape at Las Calderas is largely defined by the historical wreck, which acts as an artificial reef, attracting diverse fauna. Here, lobsters and spider crabs often seek shelter within the collapsed metal framework and rocky crevices. Patches of gorgonians provide a soft coral backdrop, while observant divers may spot various nudibranchs adhering to the wreck and surrounding hard surfaces. The steamboat's nooks and crannies are particularly rewarding for those looking to discover smaller, hidden creatures, adding an element of surprise to each dive.
