No trip to Curaçao is complete without a visit to Willemstad. Well, actually it easily could because it's at the opposite of the island as you arrive by air but I suppose there isn't so much to do that you would skip it (besides, it's a 5 minute drive from the airport). If you are coming from Europe, especially The Netherlands, then this is a waste of time though. It's basically a waterfront in Dutch style. I spent very little time here mainly because the parking is expensive like back in Europe so I stopped across the river, photoshoot, walked across the bridge and then circled around the small town a few times. It's actually super small. I later drove through it to get to the nearby beach which is more or less for drinking and partying rather than chilling.
The buildings you see are clean and neat, nice Dutch Caribbean variation of the Colonial settlements, but not all of the buildings are remains from the past and good efforts are spent that new ones will fit in with the style. Aside from the waterfront I don't think it's worth checking out anything else. It's pretty and that's all. The town itself is just shops and restaurants but on the day I visited there was also nothing going on so I suppose the atmosphere could be nicer in the evening or just other days.
