Great Blue Heron Rookery at Old Mill Site Park 🦢🌿
Here’s what you need to know 👇
Port Moody is home to an active Great Blue Heron colony along the Shoreline Trail at Old Mill Site Park. Every year, 10 to 20 nests are reoccupied or rebuilt in the trees and right now you can see them nesting from the upper trail. These massive, prehistoric-looking birds are one of BC’s most iconic species and watching an entire colony nesting above you is genuinely one of those moments that stops you in your tracks.
🗓️ When to go:
Late March to early April is peak nesting season — the best time to see the most activity. The nesting period runs from January 15 to September 15 so there is still time this spring. Go sooner rather than later for the best views.
📍 Where exactly:
Take the UPPER trail at Old Mill Site Park — the rookery is best viewed from the elevated path, not the lower beach trail
🦢 Fun facts about Great Blue Herons:
🐟 Their diet is mostly fish — but also includes shellfish, amphibians and small mammals
📏 They are the largest heron in North America — standing up to 4.5 feet tall with a wingspan of nearly 6 feet
🌲 They nest in colonies called rookeries — returning to the same trees year after year
🔇 They are sensitive to noise during early nesting — keep your voice low and give them space
⚠️ Please be respectful:
Stay on the trail. Keep noise to a minimum. Do not disturb the nests. These birds return here every single year — let’s make sure they keep coming back.

Visiting the Great Blue Heron rookery at Old Mill Site Park is truly a unique experience that offers more than just birdwatching. Over multiple visits during the nesting season, I found the elevated upper trail offers the best vantage point to observe these majestic birds without disturbing their habitat. The sheer size of the herons, with wingspans approaching 6 feet, and their prehistoric appearance, make watching their nest-building and chick-rearing activities captivating. From personal observation, the timing of your visit can make a big difference. Early spring, especially late March and early April, provides an opportunity to see active nesting when herons are busy rebuilding or maintaining nests. By mid to late summer, chicks start to fledge, and the activity changes, so earlier visits promise more dynamic sights. Something to keep in mind is the sensitivity of the herons to noise and disturbance. I noticed that keeping conversations low and sticking to the designated upper trail allowed for better and longer views without causing stress to the birds. It's vital for all visitors to respect these guidelines to ensure the herons continue returning every year. Additionally, the park’s free parking on Murray Street makes access easy for those coming from around Metro Vancouver. Connecting to Rocky Point Park and Old Orchard Park offers a chance to extend your nature walk or combine birdwatching with other outdoor activities in the Tri-Cities area. If you’re interested in the broader ecology, the Great Blue Heron’s diet includes fish, shellfish, amphibians, and small mammals, highlighting their role in the local ecosystem. Seeing a colony of such large, sensitive birds nesting so close to an urban area is a rare and special occurrence that underscores the importance of habitat conservation in BC. Overall, visiting the Great Blue Heron rookery is a peaceful and inspiring way to connect with nature in Port Moody, especially in spring when wildlife activity is at its peak. I highly recommend this hidden gem for anyone interested in birdwatching, nature walks, or simply escaping the city bustle to enjoy one of BC’s most iconic bird species.
