Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The underwater journey at Butterfly House presents a progressive exploration, beginning with a specific shore entry from a sandy beach interspersed with rocks and eelgrass. Divers must first navigate a steep and narrow path to the beach, which can be challenging, especially when carrying full gear due to slippery roots.
Careful timing for entry and exit is often necessary, as shallow rocks offshore can generate a surf break, even when the cove itself offers protection from larger swells. While initial visibility within the immediate cove might be limited, pushing out to headings between 210 and 240 degrees generally leads to clearer conditions and the site's deeper terrain. Experienced divers typically target the distant kelp beds, approximately 200 yards from shore.
Here, the true character of Butterfly House unfolds, with depths consistently over 18 meters, sometimes reaching 27 m (90 ft), offering improved visibility and impressive kelp structures that shelter a rich array of marine life. This area is a primary draw for its dramatic boulder formations and the complex habitats within the kelp forest.

Best Time to Dive
Deciding the optimal time for Butterfly House involves balancing ocean conditions and seasonal kelp growth. Dive scores suggest summer months like August and September often provide 'Good' to 'Moderate' conditions, with air temperatures ranging from 14-16°C (57-61°F) and minimal rain. However, some experienced local divers advocate for winter diving, noting better visibility due to naturally reduced kelp growth during the cooler months. Air temperatures during winter, from December to March, average around 11-12°C (52-54°F), often accompanied by higher wave heights and increased rainfall. Despite the colder conditions and potential for thick kelp on the beach, the underwater environment can offer exceptional clarity. While water temperature isn't consistently reported for this specific site, divers should anticipate colder conditions aligning with the lower air temperatures during winter, typically requiring appropriate thermal protection.

Dive Experience & Conditions
The physical approach to Butterfly House sets the stage for a dive characterized by varied conditions. Accessing the site requires an arduous journey down a steep, narrow path to the beach, where slippery tree roots present a challenge. Carrying dive gear down in stages, perhaps tanks first, is a common strategy to manage this descent safely. After storms, the beach itself can be covered in thick layers of kelp, making walking difficult before water entry. Entering the water is often easiest at high tide, which simplifies navigating past the eelgrass and rocks. Within the cove, currents are generally mild, yet shallow rocks offshore can create surf, particularly during swells. Underwater, depths range from shallower areas near the shore to a maximum of 27 m (90 ft) in the outer kelp beds. Visibility can vary significantly, starting with perhaps 1.5 meters, or five feet, in the immediate cove and improving to 7.5 meters (25 ft) or more in deeper sections, especially during periods of reduced kelp. The site's boulder fields become more prominent as divers venture away from the entry point.
Dive Difficulty & Safety Guidelines
Diving Butterfly House requires careful attention to a few site-specific considerations. The steep access path to the beach demands caution; divers might find it safer to transport gear in stages rather than attempting a single descent with full equipment. On the beach, be mindful of gulls; don't leave unattended items they might pilfer or drag off. Once in the water, particularly during the entry and exit, timing with high tide simplifies the process. Navigating to and from the dive site relies heavily on reciprocal headings, typically between 210 and 240 degrees, to ensure a direct return to the exit point. Parking is also notably limited on Stewart Way, requiring early arrival or alternative arrangements.

Depths at Butterfly House vary from shallower areas near the beach, around 4.5 meters, to a maximum of 27 meters in the more distant kelp beds. Most recreational diving occurs within these ranges.
Is Butterfly House a suitable dive site for beginners?
Given the challenging shore entry, which involves a steep path and potential for thick kelp on the beach, it's generally recommended for certified divers with some experience in shore entries and navigating variable conditions. It's not typically considered a beginner-friendly site.
What are the parking arrangements like at Butterfly House?
Parking is quite limited, primarily available on Stewart Way for about three cars. Early arrival is advisable, especially on weekends, or divers should consider carpooling or alternative transport to avoid issues.
How does kelp affect diving at Butterfly House?
Kelp density significantly influences the dive experience. Dense kelp forests are a major feature, but heavy kelp can make walking the beach difficult and reduce visibility in shallower areas. Less kelp, often observed in winter, can lead to better underwater visibility in deeper sections.
Are there any specific navigation tips for this site?
Many divers recommend using a reciprocal navigation path, typically following a heading between 210 and 240 degrees from the entry point. This helps ensure a straightforward return to the exit location after exploring the distant kelp beds and boulder formations.
What unique marine life might I see here?
Beyond a variety of fish and invertebrates, divers might encounter larger species such as sharks, whales, dolphins, and turtles, especially in the more open water areas. The site is known for its diverse cold-water marine life within the kelp forest environment.
