Despite the name some visitors use, there isn’t a formal “Costello Creek Boardwalk.” The signed site here is the Costello Creek Picnic Ground, about 1 km up Opeongo Road from km 46.3 on Highway 60. It’s a low‑key place to spread out lunch and stage a mellow day along Costello Creek and the Lake Opeongo corridor.
Expect a creek-and-wetland setting where you can watch for wetland birds, dragonflies, and the classic Algonquin bog vibe nearby. The broader Costello Creek/Opeongo area is known as a calm paddle route with the chance—never guaranteed—to spot wildlife like moose or beaver.
This day‑use spot has picnic tables, toilets, and a small pull‑off/lot. Don’t count on campfire rings; visitors report no dedicated firepits, and any fixed grills may or may not be available. A valid Algonquin day‑use vehicle permit is required, which you can reserve up to five days ahead.
You’re a short drive from the Algonquin Visitor Centre, the Logging Museum, Beaver Pond Trail, and the Lake Opeongo access—easy add‑ons before or after lunch. If you’re after a true boardwalk experience, head to Spruce Bog Boardwalk on Highway 60.
Shoulder seasons tend to be more comfortable, with fewer bugs. Mosquitoes peak around mid‑June, so plan accordingly. Any clear daylight window works well for an unrushed picnic and wildlife scanning.
