A Second Lake Most Visitors Skip
Long Lake sits just off the Island Highway on Nanaimo's north side, narrow and elongated as its name suggests, with residential streets backing onto one shore and a public park and beach on the other. It's smaller in profile than Westwood Lake, Nanaimo's better-known swimming spot, and gets treated by a lot of visitors as the backup option rather than the destination itself. That's mostly a matter of name recognition rather than the lake being lesser — the water quality and setting are comparable, and the smaller crowd is arguably the better trade.
The main park access sits at the lake's south end, with a grass area, a sandy stretch of shoreline, and a swimming raft anchored a short distance out for anyone who wants to swim past the shallows. Lifeguards typically staff the beach during the warmest stretch of summer on a set schedule rather than all season, so it's worth treating the area as an unsupervised swim outside of peak weeks and adjusting expectations accordingly.
Getting In the Water
The lakebed slopes gradually near the beach, which makes it manageable for families with younger kids who aren't strong swimmers yet, though the drop-off gets more noticeable further from shore. Water temperature climbs through July and August the way most shallow interior lakes on the island do, generally comfortable for swimming without a wetsuit by mid-summer. Early morning is the calmest time to be on the water if you're bringing a paddleboard or an inflatable rather than just swimming, since afternoon can bring enough boat and personal watercraft traffic on busier weekends to make the lake feel considerably smaller.
The Trail Around It
A dirt and gravel path runs most of the way around Long Lake, mixing open shoreline sections with stretches that duck into second-growth forest along the western edge. The full loop is short enough to finish well within an hour at an easy pace, with a few informal side trails branching off toward quieter viewpoints that don't see much foot traffic even on busy days. It's a flatter, more forgiving walk than most of the forested trails further from town, which makes it a reasonable option for anyone looking for a short outing rather than a full hike.
Facilities and Practical Notes
Parking is available at the main park entrance but fills up on hot weekend afternoons, so arriving before midday improves the odds of a close spot. Washrooms and picnic tables are on site near the beach, along with a playground that keeps the park a reasonable stop for families even outside swimming season. There's no rental outfit at the lake itself, so paddleboards, kayaks, and other gear need to come with you rather than being picked up on arrival.
Dogs are allowed in designated areas of the park but kept out of the main swimming beach during the supervised season, which is worth knowing before showing up expecting off-leash access along the whole shoreline.
Long Lake vs Westwood Lake
The comparison to Westwood Lake comes up constantly, and the honest answer is that neither is clearly better — they serve slightly different purposes. Westwood has more infrastructure, a longer perimeter trail, and a stronger claim as Nanaimo's default swimming lake, which is exactly why it draws bigger crowds on a sunny Saturday. Long Lake is smaller and more residential in feel, better suited to a quick after-work swim or a lower-key family outing than a full day trip. Anyone staying near central Nanaimo for more than a few days will likely end up at both at some point, and comparing them directly is more useful than picking one sight unseen.
Water clarity at both lakes shifts through the season, generally best earlier in summer before warmer temperatures encourage more algae growth toward late August. Neither lake is spring-fed, so both respond to a stretch of hot, dry weather the same way — slightly warmer, slightly less clear — and neither is meaningfully cleaner than the other on that front. If crowding is the deciding factor, Long Lake's smaller profile and lower name recognition among visitors keep it the calmer choice through peak summer weekends specifically.
Fishing and Other Uses
Long Lake sees some casual freshwater fishing, mostly from shore or a small boat rather than anything resembling a charter operation, and it's a much lower-key scene than the saltwater charter fishing that runs out of Nanaimo Harbour. A provincial freshwater licence is required for anyone fishing the lake, separate from the tidal-waters licence needed for ocean fishing elsewhere around the city, which catches out visitors who assume one licence covers both.
The park around the lake also sees a fair amount of casual use that has nothing to do with swimming at all — dog walking on the permitted sections, an evening jog on the loop trail, or simply a quiet spot to eat lunch away from the busier downtown parks. That everyday, low-key use is part of what keeps Long Lake feeling more like a neighbourhood park than a tourist stop, even though it's genuinely open to anyone passing through.
For current beach supervision schedules and park amenities, the City of Nanaimo maintains up-to-date information on its parks and recreation pages, which is worth checking before a visit timed around lifeguard hours specifically.
