The Leiestreek, or Lys Region, follows the gentle meanders of the River Leie as it winds southwest from Ghent through quiet meadows, medieval villages, and some of Belgium's most storied artistic landscapes. This is the countryside that captivated a colony of painters in the early 1900s, whose impressionist and expressionist masterpieces put villages like Sint-Martens-Latem and Deurle on the cultural map. Today the region draws visitors with its riverside cycling paths, art museums and galleries, fine dining, speciality beers, and one of Belgium's most photogenic castles at Ooidonk.
Your best window for the Leiestreek runs from late May through early October. This stretch covers the full outdoor season: long evenings ideal for cycling the riverside paths, castle interiors open for guided tours, kayak and boat rentals in full operation on the Leie, and terrace dining at its best in the region's villages. Summer brings the warmest temperatures and the longest days, while September offers a quieter, slightly cooler alternative with noticeably thinner crowds. If you'd prefer a shoulder season visit, April and early May are appealing for their low rainfall and the opening of castle tour schedules, though mornings can still feel sharp.
Spring in Leiestreek, Belgium
The Leiestreek comes back to life slowly in March as galleries in Sint-Martens-Latem and Deurle resume regular schedules and the first cyclists appear on the riverside paths. Mornings are cool at 42°F (5.6°C), so pack a warm layer for early walks along the Leie. By April, one of the driest months in the region, the countryside explodes with green and Kasteel Ooidonk opens its interior for guided tours, letting you explore its Renaissance architecture, tapestries, and antique-filled rooms through October. Easter holiday closures can affect shops and services, but the festive atmosphere in the villages is worth the trade-off.
Afternoon highs climb to 58.4°F (14.7°C) on average across the season, comfortable enough for extended bike rides between Ghent and Deinze along the flat towpaths that follow the river. Sporadic rain (one to three wet days in a typical stretch) means a packable waterproof jacket will earn its place in your bag. By May, daylight stretches past 9:30 PM, giving you long evenings to linger on a village terrace with a regional beer. Tourism picks up noticeably through these months, making the Leiestreek the second busiest it gets all year, and accommodation fills faster around the public holidays that cluster in late April and May, including Labour Day and Ascension Day.
Summer in Leiestreek, Belgium
Summer is when the Leiestreek fully rewards a visit. The River Leie becomes a playground: kayak and canoe rentals launch from multiple points, and boat hire lets you explore the waterway at your own pace. Afternoons warm to seasonal highs of 71.8°F (22.1°C), soft and pleasant rather than oppressive, and the sun lingers until after 10 PM in June, giving you enormous days to fill. The art museums of Deurle are at their best now: the Gust De Smet Museum and Museum Dhondt-Dhaenens both sit in the leafy landscapes that originally inspired the Flemish expressionists who worked here. Cycling through these same meanders and green banks, you can see exactly why the painters stayed.
In early August, peak heat pushes highs to 74.8°F (23.8°C) with overnight lows of 54.8°F (12.7°C), still mild by continental standards. Rain arrives slightly less often than you might expect for Belgium, with roughly two to four wet days in a given stretch, usually as brief afternoon showers rather than all-day downpours. Belgian National Day in late July can bring local festivities, and Assumption Day in mid-August is worth noting for potential shop closures. This is the region's busiest period, so book accommodation ahead, especially in Sint-Martens-Latem where options are limited.
Pack light layers: evenings by the river cool to seasonal lows of 54.4°F (12.4°C), and a light sweater makes terrace dining comfortable after sunset. The flat terrain and well-maintained cycling node network make it easy to cover ground without breaking a sweat, even in the warmest weeks.
Fall in Leiestreek, Belgium
September is the Leiestreek's quiet reward. Visitor numbers drop meaningfully from the summer peak, and the cycling paths feel almost private again. Highs still reach 59.5°F (15.3°C) across the season, warm enough for comfortable riding, and rain stays relatively moderate in September itself, one of the drier months in the region. Kasteel Ooidonk continues its guided interior tours through October, so you can still explore the castle's onion-domed towers and period furnishings without the summer crowds. The riverside meadows and polders start to shift toward golden tones, making this a particularly photogenic time for the landscapes that once drew the Latem School painters.
As October arrives, daylight shortens noticeably and mornings grow cooler at 46.3°F (7.9°C). Accommodation prices drop from summer levels, giving you more options on a budget. November is the wettest month, with roughly a third of days bringing significant rain, and All Saints' Day in early November may close some shops and services. By late November, the sun sets before 5 PM and the countryside turns inward. A warm waterproof coat becomes essential for any outdoor time, and you'll want to plan around the shorter days by focusing morning hours on cycling or walking and saving afternoons for indoor gallery visits in Deurle.
Winter in Leiestreek, Belgium
Winter strips the Leiestreek down to its essentials. The flat river landscape turns grey and atmospheric, with highs reaching only 43.9°F (6.6°C) and lows hovering near 34.3°F (1.3°C), barely above freezing on many mornings. Rain is frequent, with two to four wet days common in any given stretch, and December tends to be one of the windier months. Kasteel Ooidonk closes its interior tours for the season, though the park and gardens remain accessible for a moody winter walk. With just eight hours of daylight in December, outdoor sightseeing windows are short.
This is the region's quietest period for tourism, and many of the smaller restaurants and attractions in the villages keep reduced hours or close entirely. Christmas and St. Stephen's Day in late December bring warmth indoors, and nearby Ghent's winter festivities are an easy trip if you're based in the Leiestreek. Dress in warm, waterproof layers: the damp cold along the river cuts through lighter jackets quickly. For visitors determined to come now, the art galleries and house museums of Sint-Martens-Latem offer a reflective, crowd-free experience on the days they're open.

Travel Tips & Safety for Leiestreek, Belgium
The Leiestreek is best explored by bicycle. The region uses Belgium's cycling node (knooppunt) network, a numbered junction system that lets you plot custom routes along flat, well-signed paths between Ghent and Deinze. Bikes can be rented in Ghent or at points along the route. If you prefer public transport, De Lijn buses connect Sint-Martens-Latem and Deurle to Ghent, and Deinze has a train station on the Ghent-Kortrijk line. A car gives you the most flexibility for reaching Kasteel Ooidonk and the more scattered village attractions, but parking in the small villages is straightforward.
The Leiestreek is a safe, low-crime area with no particular concerns beyond standard travel sense: keep valuables out of sight in parked cars, and lock your bicycle when stopping at museums or restaurants. Cobblestone village streets can be slippery when wet, so sturdy shoes with good grip are worth packing, especially outside of summer.
