Arubus is Aruba's government-owned public bus system, and it's a convenient and affordable way to get around if you're not renting a car. The bus network covers most of the island, including all the major hotel areas, downtown Oranjestad, popular beaches, and even some residential neighborhoods. Buses are air-conditioned, clean, and safe, and the drivers are generally friendly and helpful if you have questions about your route or stop. There are visible signs on the side of each bus showing which hotels and destinations that particular route serves, so you'll know if it's the right one for you.

Buses run frequently along the main hotel strip, with service every 15 minutes from 5:45 AM until 6:00 PM. After 6:00 PM, buses continue running but on a reduced schedule—every 40 minutes until around 11:30 PM. The central bus station (or main bus terminal) is located in downtown Oranjestad, right next to the cruise terminal and Royal Plaza Mall. From there, buses fan out to destinations all over the island. You can check the full schedule, route maps, and real-time bus tracking on the official Arubus website at arubus.com.

Fares are very budget-friendly: $2.60 USD (AWG 4.50) for a one-way trip, $5.00 USD (AWG 8.75) for a round-trip ticket, or $10.00 USD (AWG 17.50) for an unlimited day pass. If you plan to use the bus often, you can also get a SMARTCARD for AWG 15.00 (about $8.33 USD), which offers discounted fares of AWG 3.50 ($2.00 USD) per ride. You can purchase SMARTCARDS at various locations around the island, including hotel gift shops, supermarkets, and the Arubus stations. Just pay the driver directly when you board using cash (US dollars or florins work fine). Keep in mind that Arubus does not operate 24/7, so if you're planning a late-night outing, you'll need to arrange a taxi or rideshare for the ride home.
