AT A GLANCE
Why go?
Tucked in the forest of inner Småland, Bosarydssjön is the kind of lake most visitors to Sweden never find — a small, still stretch of water ringed by woodland, with a quiet little bathing spot that feels like a local secret. It isn't a grand scenic showpiece, and that's exactly its appeal: a calm day of swimming, a picnic on a wooden jetty and a walk through pine and spruce without a crowd in sight.↗↗
The lake sits in Vaggeryd municipality in Jönköping County, about 1.3 kilometres south of the village of Hagafors. It's shallow and compact — roughly a 7-hectare mirror of water at 198 metres elevation, no more than 6.5 metres deep at its maximum — and its outflow, the Kinnebrobäcken brook, threads its way down toward the Lagan river valley. For anyone who wants a low-key Swedish summer day of water and woods, this is a genuinely restful corner of the country.↗↗
A swimming spot that rewards the detour
The heart of any visit is the badplats — the official bathing area on the lakeshore. Set back 1.3 kilometres south of Hagafors, it's the sort of place a regional newspaper singled out among the "summer pearls" of Vaggeryd precisely because it's so unshowy: seclusion meets surprisingly good facilities. On a cloudy weekday the reporter visited and didn't meet a single other person, which tells you what you're getting — a peaceful swimming hole rather than a busy lido with ice-cream kiosks and diving towers.↗
What it does have is well-judged kit for a family afternoon: a changing room, toilets, picnic tables, a wooden jetty for sunbathing and launching yourself into the water, and a small slide sized for young children. The shallow, warm lake is naturally child-friendly, so a jetty, a slide and a packed lunch are about all you need for a contented couple of hours by the water.↗
Walking and watching the water's edge
If swimming isn't the plan, the lake makes a fine focus for a hike. A marked loop out of Hagafors — commonly logged as the Hagafors–Bosarydssjön loop — runs about 6.1 km with roughly 148 m of climbing, generally rated moderate and taking around an hour and a half to two hours. It threads through classic Småland highland forest and passes the lake on its way back, so the round mixes woodland trail with a view over the open water.↗
Hikers describe the route as good for birdsong, wildflowers and wildlife, and typically quiet — the surrounding catchment is mostly forest, which is why the area feels so enclosed and green. Do note that trail conditions vary: at least one visitor reported overgrown stretches, and parts of the shoreline are private land, so keep to the trail and check current local signage before heading out expecting a manicured lakeside path.↗↗
Fishing and other slow pleasures
As with most small inland lakes in Jönköping County, fishing here is governed by the rights-holder rather than open to everyone, and a permit (fiskekort) issued by the local fishing-water association is typically required before you cast a line. If angling is on your list, check the current owner or association and rules for this specific water before you go — small Småland lakes can be privately managed even when they look invitingly public. Otherwise, Bosarydssjön is best enjoyed at bathing-spot pace: a swim off the jetty, coffee on a bench, and the stillness of a shallow forest pool.↗
Planning your visit
Bosarydssjön is a summer-season destination, at its best from roughly late June to August when the shallow water warms and the bathing facilities are in use. It lies in the countryside of Vaggeryd municipality, a short drive from the E4 corridor and the towns of Vaggeryd and Skillingaryd, with Hagafors the nearest village — you'll want your own transport to reach the trailhead and the swimming jetty.↗↗
Pack for a simple, self-sufficient outing: towels, a change of clothes, food and drink for a picnic, water shoes if you prefer not to wade into a soft lake bottom, and insect repellent for the evenings by the water. Because the spot draws few visitors, don't expect on-site cafés or lifeguards — the changing room, toilets and jetty are the extent of the built facilities, which is part of the charm.↗
What makes it special
A secluded, well-equipped swimming spot with a jetty, changing room, toilets, picnic tables and a child-sized slide — a local "summer pearl" rather than a busy lido.↗
A quiet 6.1 km moderate loop from Hagafors passes the lake, good for forest walking, wildflowers and birdsong.↗
A small, shallow forest lake — about 7 hectares, max 6.5 m deep at 198 m elevation — draining via the Kinnebrobäcken toward the Lagan river.↗
Best visited in midsummer (late June to August); bring your own transport, food and swim kit, as facilities are simple and crowds virtually absent.
A little planning goes a long way
- Driving is effectively essential: the bathing jetty sits about 1.3 km south of Hagafors, off the main E4/Vaggeryd corridor, and is not a public-transport destination.↗
- Before fishing, verify the current fishing-rights holder or association and buy the required permit (fiskekort) — small lakes in Jönköping County are usually privately or association-managed.↗
- Respect private land around the shoreline and keep to the marked trail on the loop; some routes can be overgrown, so check recent conditions.↗
- Treat it as a self-service outing: there is no café, kiosk or lifeguard, so bring water, food, towels and swim shoes, plus repellent for dusk.
