Watermael-Boitsfort: The Brussels Neighbourhood Guide for People Who Want Trees, Not Traffic

Most newcomer guides steer you toward Ixelles, Saint-Gilles, or the EU Quarter fringe, and for good reason: they're central, social, and well covered by coliving operators. Watermael-Boitsfort (Watermaal-Bosvoorde in Dutch) rarely makes that list, and it's a genuinely different kind of neighbourhood as a result. It sits in the far south-east of the city, pressed directly against the Sonian Forest, and it feels less like "Brussels" and more like a leafy town that happens to have a tram line into the capital. If the version of Brussels you actually want involves trees, quiet streets, and a lake within walking distance, it's worth a proper look before autumn sets in.

This guide covers what the commune feels like day to day, how to get around, what rent and coliving realistically look like there, and who it suits.

The Short Version

Watermael-Boitsfort is Brussels' most wooded commune by a wide margin. Roughly half its territory is covered by the Sonian Forest (Forêt de Soignes), a beech forest that stretches south toward Waterloo and beyond, and the rest is low-density, mostly residential streets dotted with two genuinely distinctive pockets: the garden-city quarter of Le Logis-Floréal and the area around the old hippodrome and the Boitsfort ponds. It's one of Brussels' smaller communes by population, and it feels like it, quiet, green, and noticeably calmer than anywhere inside the inner ring.

Why People Are Moving Here

The Sonian Forest, Right on Your Doorstep

This is the headline reason. Few European capitals let you step off a tram and into tens of thousands of hectares of ancient beech forest within minutes. Watermael-Boitsfort is the commune with the most direct access to it, and residents genuinely use it, for running, cycling, dog walks, or just decompressing after a day of screens. If you already know Brussels through our guide to the city's parks and green spaces, think of Watermael-Boitsfort as the neighbourhood built around the biggest green space of them all.

Le Logis-Floréal

One of Brussels' most architecturally distinctive quarters, a garden-city development from the 1920s inspired by the English garden-city movement, with curving streets, brick cottages, shared green courtyards, and a deliberate absence of straight Haussmann-style avenues. It's protected heritage today, and walking through it feels closer to a small English or Dutch town than the Belgian capital. Not everyone's taste, but for anyone tired of dense apartment blocks, it's a revelation.

The Boitsfort Ponds and the Old Hippodrome

The Étangs de Boitsfort, a chain of ponds bordering the forest, are a favourite for a slow evening walk, and the site of the former Boitsfort racecourse nearby has been steadily repurposed over the years into event and leisure space rather than sitting derelict. Together they give the commune a genuine sense of place beyond just "the green edge of the city."

Proximity to Boondael and Flagey

Watermael-Boitsfort borders the Boondael side of Ixelles, home to ULB's Solbosch campus, and sits a manageable tram ride from Flagey, one of the city's best-loved squares for cafés, cinema, and its own weekend market. Our Ixelles vs Saint-Gilles comparison covers that more central axis in detail if you want to weigh the two areas against each other.

Getting Around

Tram 94 is the commune's main artery, running from the Boitsfort terminus through Boondael, Flagey, and Ixelles into the city centre, a slower but scenic ride that gets faster the further your daily destination sits along that same line. Watermael-Boitsfort also has its own SNCB train stations (Boitsfort and Watermael) on the line toward Ottignies and Louvain-la-Neuve, useful if your commute runs through Brussels-Luxembourg or beyond the city rather than into the core.

Cycling is genuinely pleasant here by Brussels standards, wide, quieter streets, forest paths, and far less traffic than the inner communes, though the actual distance to the centre is longer than from Ixelles or Saint-Gilles, so factor that in if you're commuting daily by bike.

Rent and Cost of Living

This is where Watermael-Boitsfort breaks from the "hidden cheap gem" pattern of communes like Forest or Schaerbeek. It's a sought-after, relatively affluent commune, and rents for houses and larger apartments reflect that. Where it does offer value is space, you're generally paying for square metres and quiet rather than proximity to nightlife, which suits a different kind of budget calculation. If you're comparing options city-wide, our Brussels rent prices overview is a useful baseline before you start viewing.

Day-to-day costs around the commune's small local shopping streets are reasonable, though you'll do bigger grocery runs and most restaurant nights elsewhere, this isn't a neighbourhood built around a dense café scene.

Coliving in Watermael-Boitsfort

Coliving houses directly inside the commune are rare, its housing stock leans toward family homes rather than the shared apartments coliving operators typically convert. That said, it's realistically within reach of operators covering the Ixelles and Boondael axis just across the commune line, giving you forest access without giving up on a coliving arrangement entirely.

Because coverage shifts throughout the year and few operators advertise a "Watermael-Boitsfort" listing specifically, your best move is to browse the full directory of coliving actors and filter by the neighbouring Ixelles and Flagey areas, or use the coliving matchmaker to describe what you actually want, quiet, green, forest-adjacent, and let it surface houses within realistic reach of the commune.

Who Watermael-Boitsfort Suits

• Remote workers and anyone craving quiet over being in the thick of things
• Runners, cyclists, and dog owners who want forest trails rather than a park loop
• Families drawn to the garden-city streets and the calmer pace
• People with a longer runway on budget, who'd rather pay for space and greenery than nightlife on the doorstep
• Anyone already anchored around ULB or Flagey who wants a quieter home base nearby

It's a poor fit if you want a five-minute walk to bars and restaurants every night, or if you're on a tight coliving budget, for that, the denser, more affordable communes covered in our neighbourhood guides will serve you better.

Practical Notes Before You Move

• Walk the forest edge and Le Logis-Floréal separately. They're both part of the commune but feel like different neighbourhoods entirely, see both before deciding.
• Time your actual commute, not the map distance. Tram 94 is scenic but not fast; check your real door-to-desk time before committing.
• Compare against Ixelles and Boondael directly. If forest access matters less than you think it will, the busier, better-connected communes next door might suit you better.
• Handle registration the standard way. Once you've found a place, commune-level registration follows the same process used across the city, our guide on how to register as an expat in Brussels walks through it if it's new to you.

The Bottom Line

Watermael-Boitsfort won't suit everyone, and it isn't trying to. It's the commune for people who'd genuinely rather live next to a forest than a nightlife strip, and who are willing to trade some centrality and coliving choice for that. If that trade sounds right to you as the days shorten and the forest starts turning colour, it's worth a weekend of exploring before you commit elsewhere. Compare it against the rest of the city through our neighbourhood guides, and use the coliving matchmaker to see what's realistically within reach of it right now.
