What's the must-see thing in Palm Beach?

Most visitors to Palm Beach spend 7 days within 500 metres of the shoreline and leave thinking Aruba is a beach with hotels on it. Arikok National Park, established in 2000, sits 12 km east and covers about 20% of the island. The landscape is volcanic basalt, wind-sculpted divi-divi trees bent permanently westward, and towering columnar cacti that smell faintly sweet after a rare rain. Fontein Cave holds Arawak petroglyphs estimated at 1,000 years old, the red and brown pigments still visible on the limestone ceiling. The Natural Pool, a rock formation where the sea pushes through gaps in volcanic stone, requires either a licensed 4x4 tour (around $85 per person through most hotel desks) or a 45-minute hike over loose rubble in full sun. Wear closed-toe shoes. The park opens daily at 8am, entry is $15, and by 11am the exposed rock radiates enough heat to make the trails uncomfortable. The parking lot at Boca Prins fills with tour buses by mid-morning.

Alto Vista Chapel sits on a limestone bluff on the north coast, about 10 minutes by car from the high-rise strip. The current building dates to 1952, on the site where a Spanish missionary established Aruba's first Catholic chapel around 1750. It is a small, bright-yellow structure that seats maybe 30 people. The wind up here is constant, loud enough to muffle conversation, and the view north is open ocean all the way to the horizon. The approach road passes the Peace Labyrinth, a stone walking path that takes about 15 minutes to complete. To be fair, the chapel itself is a 5-minute stop. The real draw is the drive along the north coast afterward, past the ruins of the Bushiribana Gold Mill from the 1820s and the Natural Bridge that collapsed in 2005, with a smaller natural bridge still intact beside it. The whole loop takes under 2 hours and costs nothing except fuel.

Palm Beach itself, the roughly 2-km strip of white sand between the Riu Palace and the Marriott, tends to get dismissed as the hotel beach. That is a mistake. The sand is fine-grained and stays cool underfoot even at midday because the constant trade winds off the Caribbean keep the surface temperature manageable at 12°N latitude. The water currently sits around 28°C and stays clear to about 15 metres depth. The best stretch for swimming is the 400 metres in front of the Hyatt Regency, where a natural sandbar keeps the depth under chest-height for 50 metres out. Sunbed rentals through hotels run $15-25 per day. Walk to the public-access sections between the Riu and the Holiday Inn and you can drop a towel for free. Sunset from this beach drops directly into the water, and in June the sun goes below the horizon around 7:05pm.

You do not need a rental car for Palm Beach itself, but you need one for Arikok and the north coast. Budget $45-65 per day from local operators like Top Drive or Amigo, which tend to run $10-15 cheaper than Hertz or Avis at the airport. Roads are paved and well-signed, driving is on the right, and the island is only about 30 km long. Arikok's 4x4-only trails to the Natural Pool and Boca Prins are seriously rough, not marketing rough. A sedan will bottom out. If you want the Natural Pool without renting a 4x4, book a UTV tour for $85-120 per person, about 3 hours. Skip the submarine tour and the Butterfly Farm that every hotel lobby promotes. Neither is terrible, but on a short trip they eat half a day you could spend at Arikok or in the water.
