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.
Arikok National Park covers about 34 square kilometers, 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 on the Ramsar register of internationally important wetlands.

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 National Park, on the windward side
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. As of October 2026 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. The Natural Pool is reached on foot, on horseback or by 4x4, according to the Aruba Tourism Authority, and swimming there is only safe when the ocean is calm. The foundation prohibits ATVs, UTVs and motorbikes in protected nature areas, so plan on a jeep safari, a horseback tour or an early walk in from San Fuego, 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, is managed by the same foundation. It is not one continuous reserve. The foundation describes four marine protected areas totalling 6,020 hectares of coastal water: one off Arikok on the windward coast, one at Seroe Colorado, one at Mangel Halto and one off Oranjestad. We could not verify the exact boundaries of each zone, so they are not described here. Unlike Arikok, the marine park has no gate.
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.
Wetlands, birds and the Ramsar register
Bubali Bird Sanctuary sits just inland from the Palm Beach strip: two man-made bird ponds and an observation tower, as listed by the Aruba Tourism Authority. We could not confirm opening hours or an entry fee. Herons, egrets, cormorants and migratory waterfowl use it, and early morning is the cooler time to go.
Spanish Lagoon, Spaans Lagoen on Dutch maps, is the island's mangrove inlet and a Ramsar wetland of international importance. The Ramsar Convention has since announced four more wetland sites in Aruba. We could not open the announcement to confirm their dates and areas, so no figures are given here. 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.
