Aruba's parks and protected coast
4 parks and reserves to explore, from the cactus-covered hills of Arikok National Park and the churning waves of the Natural Pool (Conchi) to the Ayo and Casibari rock formations and the snorkeling coves of Boca Catalina.
Aruba has one national park, Arikok, and it covers close to a fifth of the island. The other three protected areas here work differently: a marine park split across four zones of coastal water, a freshwater bird sanctuary behind the Palm Beach hotels, and a mangrove lagoon that has been on the international register of important wetlands since 1980.
Arikok National Park
Aruba's wild desert heart, covering nearly a fifth of the island. Hike past cactus and divi-divi trees to caves, the Natural Pool, and the rugged windward coast where the open sea hammers the cliffs.
Aruba Marine Park
Aruba's network of protected marine zones along the calm leeward coast. Sheltered reefs, seagrass beds, and the famous Antilla shipwreck make for warm, clear snorkeling and diving year-round.
Bubali Bird Sanctuary
A green wetland oasis just inland from Palm Beach, where freshwater ponds draw herons, egrets, cormorants, and dozens of migratory birds. Climb the watchtower for a free, easy escape into nature.
Spanish Lagoon
Aruba's most important mangrove inlet, a calm, sheltered lagoon ringed by red mangroves. A protected Ramsar wetland that shelters birds, young fish, and the island's best mangrove kayaking and paddleboarding.
Arikok, the island's only national park
Arikok National Park covers about 34 square kilometers of Aruba's north-eastern, windward side, close to a fifth of the island's land, and has been formally protected since 2000. Within its boundaries are the Fontein and Quadirikiri caves, Arawak rock drawings, Jamanota at 188 meters (the highest point on the island), and the wave-fed Natural Pool, known locally as Conchi.
Entry is a conservation day pass. It costs US$22 per adult, and children under 17 go free. There are two gates: San Fuego, inland from Santa Cruz, open daily 08:00 to 15:30, and Vader Piet in the south, open 08:30 to 15:00. The park is run by the Aruba Conservation Foundation, formerly the Fundacion Parke Nacional Arikok, which publishes current pass prices and gate times at acf.aw.
The marked trails are walkable without a guide, but the interior tracks out to the Natural Pool need four-wheel drive, so most visitors either book a jeep safari or walk in from San Fuego early, before the heat. The windward beaches inside the park, including Dos Playa, are for looking at rather than swimming: the surf and the currents there are dangerous.
What the marine park protects
Marine Park Aruba, or Parke Marino Aruba, was established in December 2018 and came under the same foundation's management in April 2019. It is not one continuous reserve. It is four separate zones of coastal water totalling 60.2 square kilometers, or 6,020 hectares of mangrove, coral reef and seagrass: the water off Arikok on the windward coast, Seroe Colorado around the eastern cape, Mangel Halto with its mangroves and the islets of Isla di Oro and Santo Largo, and the Oranjestad reef islands between Governor's Bay and Punta Brabo, with the cruise ship channel cut out of it. There is no entry fee and no gate, unlike Arikok.
The split matters when you are planning a day. The calm, shallow snorkeling most visitors expect is at Mangel Halto and along the sheltered leeward reefs, while the Arikok zone faces open sea and is not swimmable. Boat trips to the Antilla wreck and the reefs at Boca Catalina leave from the north-west coast, which sits outside the four protected zones.
Wetlands, birds, and a Ramsar list that grew
Bubali Bird Sanctuary sits just inland from the Palm Beach strip: freshwater ponds, reed beds and a wooden observation tower, free to enter and open during daylight hours. Herons, egrets, cormorants and migratory waterfowl use it through the year. Early morning is the best time to go, for the bird activity and for the temperature alike.
Spanish Lagoon, Spaans Lagoen on Dutch maps, is the island's mangrove inlet and its oldest protected wetland. It joined the Ramsar list of wetlands of international importance on 23 May 1980. In November 2023 Aruba extended it from 70 to 259 hectares and designated four more Ramsar sites, taking the island's registered wetland area from 70 hectares to 14,408. Most of that new area is coastal water, reef and salt flat rather than ground you can walk. The lagoon itself is the part you can see, from the road or from a kayak.
If you are fitting the protected areas around the rest of a trip, the things to do guide and the beach guide set out which coast suits which day.
