Why dive here
With 72+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and seahorses - Sylvan Park offers some of Goat Island & Hauraki Gulf's richest wreck diving. Water ranges 15-21°C, warmest January, February, March.
Sylvan Park, in the freshwater depths of Lake Pupuke, is a different kind of dive. Forget your usual reef expectations here. What we love about Sylvan Park is its sheer calm, a welcome change from the coastal churn. You’ll walk down a boat ramp from the car park, which makes for an easy entry, something we always appreciate. The real draw, for us, is the extensive seagrass meadow, a constant green carpet that stretches from the shore out to about ten meters. This seagrass isn't just decoration; it's a living, breathing habitat. We spend our time here really slowing down, looking for the tiny things. Think little post horn squids darting through the blades, or the subtle shimmer of a big-belly seahorse camouflaged perfectly. Keep an eye out for curious cowfish peeking from the fronds. Visibility usually sits around three meters, which means it’s a site for close inspection, not wide panoramas. It's a fantastic spot for photographers focusing on macro life, or anyone just wanting a peaceful, undemanding dive in an unusual setting.
