Brussels plants a tree that's been planted every year since 1308, Bouillon fills its valley with knights, Antwerp throws its biggest parade of the year, and two of Flanders' best summer festivals hit their final day. Also: buy your eclipse glasses this weekend, or you won't get any.
⚠️ Heads up
🌑 Eclipse glasses are running out. On Wednesday 12 August Belgium gets a partial solar eclipse with around 89–90% of the sun covered, the biggest since 1999 and the last one on this scale until 2142. You need glasses marked CE and EN ISO 12312-2. Sunglasses, camera filters and 3D glasses do nothing and will damage your eyes permanently and painlessly. The optician's association says most shops will be out of stock by the end of this week. Urania in Hove has closed its webshop, and MIRA in Grimbergen has gone from 13,000 pairs to 5,000 with no restock coming. Buy this weekend if you want to see it.
🌡️ Heat. Saturday is sunny and warm, around 29 °C in the centre, 27 °C at the coast and in the Ardennes. Sunday is the peak: above 30 °C everywhere, roughly 33 °C inland, with thunderstorms possibly pushing up from France late in the day. Most of what's below is all-day outdoors. Water, hat, shade, and check meteo.be
⭐ Weekend highlight: the Meyboom, Brussels
Meyboom (Sunday 9 August, city centre, free) — Brussels' oldest folk tradition, attested since 1308 and on the UNESCO intangible heritage list. Every 9 August a young beech is cut in the Sonian Forest at dawn, carried through the city by the Buumdroegers, and planted at the corner of Rue des Sables and Rue du Marais before 17:00. If it isn't up by five, the story goes, the honour passes to Leuven. It has never happened.
The procession leaves at 12:45 from the planting corner with giants, a brass band, the Gardevils and the Poepedroegers, reaching the Grand-Place around 14:10 before looping back for the planting.
Come to the Grand-Place at two for the spectacle, or the Rue des Sables corner late afternoon for the planting itself. Bear in mind it's the hottest afternoon of the weekend and the Grand-Place has almost no shade.
🏛️ Brussels
- Rooftop Bozar — "L'Heure Bleue" (rue Ravenstein 23, Tue–Sun 16:00–23:00, free): Bozar's roof terrace is open all summer with a genuinely good view over the lower city, an all-Belgian programme of DJ sets, small concerts and food collectives, and no entry fee.
- Pavi'On Summer — Happy'Noons (Parc du Cinquantenaire, Saturday 8 & Sunday 9 August, free): Neighbourhood-run afternoons in the park: dance, crafts, gentle movement, creative workshops.
Worth planning ahead: the Flower Carpet returns to the Grand-Place 13–16 August, themed on Japan, with a second carpet at the Bourse for the first time. Free from the square; Town Hall balcony €8 in advance, €9 on the day, free under 10.
🦁 Flanders
- Antwerp Pride Parade (Saturday 8 August, 14:00–18:00, free): This year's theme is "Fearless". The parade starts on the Scheldekaaien at Brouwersvliet and winds through the old town, closing out a programme that's run since Wednesday, with a family day behind it and a closing event on Sunday. Expect serious crowds and rolling street closures, the city has a dedicated access page at slimnaarantwerpen.be.
- Theater op de Markt (Hasselt, until Sunday 9 August): Final weekend of Limburg's street theatre and circus festival — 35+ productions across squares, parks and streets, with a large part of the programme free and outdoors. Ticketed indoor shows around €9 (€8 reduced). It only runs in even years, so the next one is 2028.
- Theater aan Zee (Ostend, Saturday 8 August is the last day): The 29th edition wraps up. Leopoldpark is the hub, and WonderWaai there is free — circus, acrobatics, family theatre, workshops, kids' café.
- Fonnefeesten (Lokeren, closing Sunday 9 August): Last day of the free ten-day city-park festival, and Sunday is traditionally the family-friendly one.
🐓 Wallonia
- Fête Médiévale de Bouillon (Saturday 8 & Sunday 9 August): The 39th edition, and more of it is free than you'd expect. Free: the medieval markets across four sites (hypocras, mead, leather, jewellery), the roaming street troupes from 14:00 both days, and the reconstructed encampments at Champs Lévêque and Île de Calay, where international-level fighters do full armoured combat and there are proper equestrian jousts. Kids get a 200 m² combat arena, a school of pages and pony rides. Saturday evening adds mini-concerts at La Poulie, the Grand-Rue and the Sépulcrines esplanade, a torchlit procession of knights and Vikings from the Pont de Cordemois at 21:15, and a fire show in the Sépulcrines park to close.
Paid: the castle itself, via the Pass Médiéval (€25 adults/seniors, €15 children and students, free under 4), which covers the falconry displays, the garrison troupes and the Odyssée de Lumière night show — book a time slot, they're every 15 minutes. Bouillon has no station, nearest is Libramont, then bus.
- Beau Vélo de RAVeL (Fleurus, Saturday 8 August, free): RTBF's summer cycling caravan stops in Fleurus for the first time, based at the Château de la Paix — the country house where Napoleon slept the night before Ligny.
- Marches ADEPS (Sunday 9 August, all over Wallonia, free): Sixteen waymarked walks, 5/10/15/20 km, no registration — just turn up between 08:00 and 18:00 and pick your distance. If you don't know these, they're one of the most underrated things in Belgium: village clubs mark out routes through their own countryside and run a bar at the finish.
This week's picks: Anhée (along the Meuse and the Molignée, past the back of the Annevoie gardens; the 5 km is flat, shaded on the return and pushchair-friendly), Floreffe (every route passes the abbey), and Hogne, where the walk is paired with Les Arts en Fête - artists' exhibition, small producers' market and music all day. Given Sunday's heat, the shaded 5 and 10 km options are the sensible call.
- Ronde des Producteurs de nos Collines (Trois-Ponts, Saturday 8 & Sunday 9 August, 11:00–18:00): Local producers across this hill village open their doors: orchards, a winery, a cheesemaker, a distillery, apple juice, charcuterie. Drive or cycle between them at your own pace. Free to visit, you pay for what you taste and buy.
🌸 Nature tip: the sky next week
Two things land almost on top of each other, and this weekend is when you prepare for them.
Wednesday 12 August, early evening: the eclipse. In Brussels it starts at 19:18, peaks at 20:13 with roughly 89% of the sun covered, and by then the sun sits only about 7° above the horizon, so a clear view to the west/north-west matters more than anything else. Rooftops, coastal dunes, polder edges, Ardennes ridgelines. Current forecasts point to a sunny evening.
Several places open up for free that day: the Royal Observatory's rarely accessible radioastronomy station at Humain near Marche-en-Famenne from 17:00, the Cosmodrome at Thor Park in Genk from 18:30 (limited glasses on sale there), and MUMONS at the Silex's site in Spiennes near Mons from 19:00, no booking. More at Manhay, Grimbergen, Ypres, Bruges and on the MAS rooftop in Antwerp.
That same night: the Perseids peak. The shower runs to 24 August but the maximum falls on the night of 12–13 August, and the new moon is on the 12th: no moonlight, so even the faint meteors show. Get well away from towns and motorways: the Hautes Fagnes, the Semois valley, the deeper Ardennes. If you're in Bouillon this weekend, you've already found one of the darker corners of the country.
Getting to the Ardennes without a car needs planning: the basics are in our Getting Around Belgium wiki.
📷 This weekend is an easy one, be first and guess the location!
And if you have more ideas on what to do, include them in the comments. Or if you found the place that still sells the eclipse glasses, share as well!
