The long June weekend in Masuria: Corpus Christi by the lake

In short: Corpus Christi (Boże Ciało) always falls on a Thursday and is a public holiday in Poland, so with one day off on Friday you get four days. In Masuria it is the start of summer: the longest days of the year, green forests, and boat cruises and kayak rentals already running, with fewer people than in July and August. The water can still be cool, especially in early June, and most shops are closed on the Thursday, so do your shopping beforehand. Book a lake house early, as the long weekend is one of the most popular dates of the year.

For many Poles, the long June weekend is the first real summer trip of the year. The May bank holiday weekend can still be chilly, and the summer holidays are yet to come. Masuria, Poland's lake district, has something of both in June: nature in full swing, warm evenings and still-quiet lakes. If you are visiting from abroad, it is worth knowing that this is a Polish long weekend, so the region is busier than on an ordinary June week. Below is everything to know before you pack the car.

Corpus Christi is a movable feast. It is celebrated 60 days after Easter, always on a Thursday, and in Poland it is a statutory day off work. It falls on 21 May at the earliest and 24 June at the latest. To check the date in a given year, add 60 days to Easter Sunday.

The most popular pattern is Thursday to Sunday: the Thursday holiday, a day of leave on Friday and the weekend, giving three nights by the lake. If you can set off on Wednesday after work, you gain Thursday morning by the water and avoid the worst traffic. In years when Corpus Christi still falls in May, the trip feels more like a late May long weekend, so our guide to the May long weekend in Masuria will come in handy.

June is the month of the longest days. In Masuria the sun sets after 21:00, so after dinner there is still light for a walk along the shore or a paddle. The forests are lush green, flowers bloom in the meadows, and on the lakes you can see families of swans and grebes with their young. It is also the start of the season for campfire evenings without a jacket.

Two things to remember. Lake water in early June can still be cool and warms up week by week, so the first swim may be a short one. Mosquitoes and ticks also appear, especially after rain, by the reeds and in the forest, so pack insect repellent from day one.

6. 06on Lake Krzywe, fishing from a boat is allowed from 1 June, not only from the shore

A shorter, three-day version of this plan is in 3 days in Masuria.

Corpus Christi is a statutory holiday, and Polish law bans most shops from trading on public holidays. On the Thursday most shops are closed, and usually on Sunday as well. Do the big shop on Wednesday or on the way, then top up with bread and small things in Mrągowo on Friday and Saturday.

On Thursday morning, processions pass through the towns, and streets in the centres are sometimes closed for a while. Most cars head to Masuria on Wednesday afternoon and Thursday morning and return on Sunday afternoon. From Warsaw to Krzywe it is about 282 km, roughly 3.5 hours without traffic. If you can, leave on Wednesday evening or very early on Thursday.

June is already on our summer price list. The whole house for up to 10 people starts at PLN 1,199 a night. Three nights from Thursday to Sunday start at PLN 3,597, and with the tourist tax for 10 adults (PLN 3.50 per person per night) from PLN 3,702, or about PLN 370 per person for the whole long weekend. For 20 people in two houses the cost per person is the same.

Add activities on top: kayaking is about PLN 60 per person, a short cruise PLN 55 and firewood PLN 200 for the whole house. We break down a full budget, with food and fuel, in What does a weekend in Masuria cost.

Our two Modern and Loft houses stand on Lake Krzywe, a quiet zone with no combustion engines. In June that means mornings with only birdsong and campfire evenings as the sun sets over the water. The shore is about 10 metres from the terrace, and a beach with a jetty about 20 metres from the houses.

Each house has 130 m², four bedrooms, three bathrooms and a kitchen with a dishwasher, and bed linen and towels are included. Mrągowo is 9 km away, Krutyń about 20 minutes and Mikołajki about 30 minutes. The deposit is 30%, and you can cancel free of charge up to 30 days before arrival.

In June, Masuria is already in full summer, but without the holiday crowds. It is hard to find a better moment for a long weekend.
