Parking regulations are quite lax on Aruba with only the capital Oranjestad suffering any major parking problems. There, you’ll have to be careful where you park to avoid parking fines for obstruction or overstaying a time limit.
You’ll find plenty of paid parking in Oranjestad as the locals take advantage of the tourist traffic. If you’re lucky, you’ll also find free parking in most places, more likely in the smaller towns or away from the commercial centres and tourist attractions.
There’s little enforcement of parking as much of it is free. You’ll only encounter police involvement in parking where a road or access is obstructed or if you overstay timed parking.
Disabled access parking is not easy to find but if you struggle, the locals are often friendly and helpful and will do what they can to help.
