How to Get There
Isla Caja de Muertos is accessible only by boat, with most tours departing from La Guancha Boardwalk in Ponce, a vibrant waterfront area with restaurants and shops. Here are your options:
By Ferry or Catamaran: Regular ferry services and private catamaran tours depart from La Guancha in Ponce. The boat ride takes about 20–30 minutes. Operators like Waterland Adventure (787-556-1568, [email protected]) and Island Venture (islandventurepr.com) offer all-inclusive trips, including snorkeling gear, lunch, and beach amenities. Prices range from $30–$75 per person for group tours or $650–$750 for private charters (4–6 people). Book in advance, especially during peak seasons (summer, weekends, and holidays).
Private Boat Charter: For a more personalized experience, companies like East Island Excursions offer private tours with customizable itineraries, including snorkeling or fishing. Contact them directly for pricing.
From San Juan: Drive 1.5 hours from San Juan to Ponce via Route 52 (Autopista Luis A. Ferré). Exit at Av. Malecón/PR-12 S and head to La Guancha’s public dock. The drive is scenic, passing through Puerto Rico’s lush mountains, with tolls costing about $5–10 round-trip.
Note: Public ferry services were interrupted after Hurricane Maria (2017) and the 2020 Puerto Rico earthquakes, which damaged La Guancha. As of 2023, services have resumed, but check with operators like Waterland Adventure for current schedules. The island is not accessible to the public without authorized transportation due to its protected status.
Best Time to Visit
Year-Round Appeal: The island’s Caribbean climate makes it a viable destination any time, with temperatures averaging 26–32°C (78–90°F). Peak Season (December–April): This is Puerto Rico’s high season, with dry weather and calm seas, ideal for snorkeling and hiking. The island is less crowded compared to summer.
Summer (June–August): Popular with locals, especially on weekends and holidays, due to warm weather and school breaks. Book tours early to avoid crowds. Avoid Rainy Season (September–November): Heavy rains and potential hurricanes can disrupt boat trips and reduce water clarity for snorkeling.
Turtle Nesting Season (May–August): Some eastern beaches may be closed to protect nesting hawksbill and green turtles, but this is a great time for wildlife enthusiasts. Tip: Check weather forecasts and avoid stormy days, as rough seas can make the boat ride uncomfortable. Early morning departures offer calmer waters and cooler temperatures.

Tour Costs: Group Tours: $30–$75 per person, including boat transport, snorkeling gear, lunch, and drinks (e.g., Waterland Adventure’s 4-hour snorkel trip or Island Venture’s 6-hour all-inclusive day trip). Private Charters: $650 for 1–4 people, $750 for 5–6 people, including lunch, drinks, beach chairs, and umbrellas. Snorkeling Gear Rental: Often included in tours; otherwise, $10–15 extra.
Ferry Tickets: Public ferries (when available) cost $10–$20 round-trip but offer fewer amenities. No Entrance Fee: As a nature reserve, the island itself has no admission fee, but access is restricted to authorized tours.
Booking Tip: Reserve through operators’ websites or platforms like Viator.com at least a week in advance, especially for private charters or peak seasons.
What to See and Do
Isla Caja de Muertos offers a mix of relaxation and adventure, with activities centered around its natural beauty and historical sites:
Playa Pelicano: The island’s main beach, awarded the Caribbean’s first Blue Flag for its cleanliness, safety, and environmental standards. Its white sand and calm, turquoise waters are perfect for swimming, sunbathing, and family-friendly fun. Amenities include shaded cabanas, picnic tables, and compost restrooms managed by the Department of Natural Resources (DNR).
Snorkeling and Diving: The island’s north-eastern reefs are teeming with colorful coral and marine life, including tropical fish and sea turtles. The Vereda Submarina (Submarine Trail) at Playa Larga features 25 educational stations highlighting local species. Bring your own snorkeling gear or rent from tour operators. Scuba diving charters are available for deeper exploration.
Hiking: A 25–30-minute trail leads to the Caja de Muertos Lighthouse, built in 1887, perched on a 170-foot hill. Its unique Cross of Lorraine design and panoramic views of the Caribbean Sea make it a highlight, though the interior is closed for safety. Another trail leads to Almeida Cave, linked to pirate legends, including the tale of José Almeida, who reportedly buried his wife’s coffin and treasure here. Trails are moderately challenging; wear supportive shoes and watch for cacti and rocky terrain.
Birdwatching and Wildlife: The island is a sanctuary for seabirds like brown pelicans, brown boobies (Sula leucogaster), and pearly-eyed thrashers (Margarops fuscatus). Endangered hawksbill turtles nest on eastern beaches (closed during nesting season). The small open-air museum near the dock offers insights into the island’s flora, fauna, and pirate history.
Kayaking and Paddleboarding: Some tours offer kayaks or paddleboards to explore the coastline’s calm waters, perfect for spotting marine life or enjoying the scenery. Relaxation: With no restaurants or shops, the island is ideal for unplugging. Lounge on Playa Pelicano, read a book, or enjoy a picnic under the sun.
Note: The museum and some facilities were damaged by the 2020 earthquakes and may be partially closed. Check with your tour operator for updates.
