What's the temperature like in Belgium during May?

The temperature reaches around 18℃ during the daytime in May, falling away to 9℃ at night. The UV index will be moderate at this time of year, so not something to worry about for the average person. However, if you're going to be outside for long periods it's worth wearing a broad spectrum SPF 30+ sunscreen and UV-blocking sunglasses. Remember that bright surfaces, such as water and sand increase UV exposure.

Weekend itinerary in Ghent, Belgium

Some people might never heard of Ghent before unlike Brussels, Bruges, and Antwerp. Despite being the country’s oldest city, Ghent is truly the gem of Belgium. This unique and romantic place is rich in medieval and classical architecture. The whole city looks like an open-air museum. The vibrant colors enrich the center of trade and culture. Its industrial ambiance is a perfect contrast for the medieval building and spectacular landscape views. This region from Western Europe is not all...

A beer lover’s guide to 36 hours in Brussels, Belgium

I’d passed through Brussels Midi station four times without ever getting any further than one overpriced bar directly outside whilst waiting for a connecting train to other towns in Belgium. The Eurostar is synonymous with a Paris city break and the recent opening of the Amsterdam route now also shares some of that limelight, but in just two hours you can be right in Belgium’s capital. I headed there for a weekend of beer drinking interspersed with some very light sightseeing...

How to visit 3 cities in Belgium in 3 days – Bruges, Brussels & Ghent

I feel like Belgium doesn’t get as visited as many other countries in Europe which is strange because it offers great architecture, chocolate, and beer and what more do you really need? If you’re looking for a short European city break from the UK or elsewhere in Europe, Belgium is a good answer because you can see a lot of places in Belgium in a short amount of time due to the size of the cities, the size of the country and a good train system. I visited Belgium for a long weekend over...

Craft beer lovers weekend itinerary in Ghent

I took a quick trip Ghent over a long weekend, taking advantage of how easy it is to get there with the Eurostar from London. I’ve been to Ghent a few times before and was always struck by how little people talk about it in comparison to Bruges, Brussels and Antwerp. I’ve always found this historic old university town fairly underrated in the grand scheme of things. Thankfully it means fewer tourists (although there’s still a fair few) and more local experiences on offer. If the lure of...

Things to do in Brussels – My top 5

The top things to do in Brussels, what are they exactly? Well obviously opinion will vary depending upon whom you ask, but I think I’ve covered a couple of the basics below. Just a shot hop from London via Eurostar, Brussels seemed like the perfect spot to kick off my travels for 2016, and I was pleasantly surprised by a city that I’ve often overlooked in favour of Paris. Well no more, Brussels is firmly on the favourites list, and somewhere I will definitely be looking to visit again in...
