Which Vessel for a Rosario Islands Day Trip?

The Rosario Islands require a full-day charter — 35 km offshore, 42-50 minute transit each way. Here is what each vessel delivers and who it is best for.

VesselCapacityFull Day (8 hrs)Best ForKey Tradeoff
Lancha 32-38ft Most PopularUp to 12$680-$950Groups of 6-12 wanting speed and flexibilityOpen-bow, fast, less shade
Large Lancha 38-42ft10-12$1,100-$1,400Extended families needing more deck spaceMore shade & comfort
Mid-Size Yacht 40-50ftUp to 17$1,750-$2,750Comfort-focused groups wanting A/C cabinSlower transit; full amenities
Catamaran 45-55ftUp to 30$1,800-$4,500Large groups, events, families with childrenMost stable; slowest (60 min)

All rates include DIMAR captain, fuel, life jackets, cooler with ice. Park fee (~$6-7 USD/person in COP cash), snorkel gear, food not included. Prices last verified April 2026.

Private vs. Shared Tour — The Real Math: A shared catamaran tour to the Rosario Islands costs ~$65-90/person. For a group of 8 that is $520-720 total, with a fixed schedule, 30+ strangers, and an 11 AM arrival that leaves you 3-4 hours before the 3:30 PM cutoff. A private lancha for 8 guests costs $680 total ($85/person) and departs at 7:30 AM, giving you 6-7 hours on the water. Break-even: 8 people. Above that, private is cheaper per person and gives full itinerary control.

What the Rosario Islands Actually Are — and Why They Are Worth the Full Day

The Rosario Islands (Islas del Rosario) are an archipelago of 27 coral islands 35 km southwest of Cartagena, forming part of Parque Nacional Natural Corales del Rosario y San Bernardo — Colombia's most-visited marine protected area. They are a functioning coral ecosystem with snorkeling, mangroves, and private coves.

27
coral islands inside a protected national marine park — park entry fee required per person
8-15m
snorkel visibility at outer reef sites, Dec-Apr dry season. Drops to 3-5m during June-Oct rainy season.
42-50
minutes by lancha from Marina Santa Cruz de Manzanillo — minimum transit time each way
3:30 PM
DIMAR-enforced maximum departure from islands — afternoon Caribbean swells make later returns unsafe
🌊
Isla Grande
~55-65 min from Marina Santa Cruz
Largest island in the archipelago. Beach restaurants, mangrove trails, and the best outer reef snorkeling. A full-day charter gives time to anchor at Isla Grande and still stop at a second site on the return.
🌅
Islote Santa Cruz
35 km offshore, shallow coral gardens
Shallow reef site at 2-5 meter depth, ideal for first-time snorkelers. Adjacent to the floating checkpoint buoy where the park fee is collected.
🌀
Isla del Pirata
Outer reef, 10-15m visibility Dec-Apr
Best intermediate snorkeling site in the archipelago. Deeper reef wall with fish variety and coral formations. Captain anchors based on current and swell conditions.
📶
Private Coves
Anchorages between islands
The main advantage of a private charter: your captain anchors between islands in spots inaccessible to large shared boats. Crystal clear water, no crowds, zero noise.

The Park Checkpoint: How It Actually Works

Nearly every Rosario Islands listing says "park fee not included" with no further explanation. Here is exactly what happens at the checkpoint so you arrive prepared.

📍 Where Is the Checkpoint?

  • A floating buoy platform in the channel before Isla Grande — approximately 35 km from Cartagena
  • Every boat entering the national park must stop here, regardless of charter type
  • A park ranger from Parques Nacionales Naturales boards or comes alongside
  • Fee is collected per passenger, individually
  • There are no ATMs or card terminals. COP cash only.

💲 What to Bring

  • COP 25,000-28,000 per person (~$6-7 USD at April 2026 exchange rates)
  • Recommended: bring $10 USD equivalent per person in small COP bills
  • Your captain handles the paperwork and coordinates with the ranger
  • Children under 5 may be exempt — confirm with captain at booking
  • Fee applies to both Colombian and foreign visitors
⚠ The cash trap: Most visitors learn about the COP cash requirement at the checkpoint, 35 km from the nearest ATM. For a group of 8, budget COP 200,000-240,000 (~$50-60 USD) for park fees. Withdraw COP before leaving your hotel.

Why Early Departure Changes Everything

The DIMAR-enforced 3:30 PM maximum departure from the islands is not negotiable. Caribbean afternoon swells in the Rosario Islands channel reach 1.5-2 meters between 3:00-5:00 PM, and every licensed operator must comply. Your time on the islands is determined entirely by when you depart Cartagena.

What a Private Rosario Islands Charter Looks Like — Hour by Hour

A representative full-day itinerary for a group departing at 7:30 AM. Your captain adjusts based on sea conditions, guest preferences, and park access on the day.

7:00 AM
Arrive at Marina Santa Cruz de Manzanillo. Meet your captain at the assigned slip. 5-minute DIMAR safety briefing. Confirm snorkel gear, cooler, and route plan.
7:30 AM
Departure. Open Caribbean water 10 minutes after leaving the marina. Transit approximately 42-50 minutes depending on sea state.
8:20 AM
National park checkpoint. Captain stops at the floating buoy. Ranger collects fees. Have your COP cash ready. Takes 5-10 minutes. Then the boat enters the marine park.
8:30 AM
First snorkeling stop. Captain selects site based on conditions — typically Isla del Pirata outer reef or Islote Santa Cruz coral garden. Visibility at this hour: 10-15m Dec-Apr. Approximately 60-75 minutes.
10:00 AM
Isla Grande. Anchor at the main island. Beach time, optional lunch at a beach restaurant (pay separately), explore mangrove edge. Shared tours arrive around this time — you have already been here 1.5 hours.
12:30 PM
Private cove anchorage. Captain moves to a quiet anchorage between islands — no other boats. Lunch on board. Swimming off the stern.
2:00 PM
Second snorkel stop or beach. Optional return to a snorkeling site or second island visit. Captain monitors the 3:30 PM cutoff.
3:00 PM
Begin return. DIMAR regulations require departure by 3:30 PM maximum. Return transit: 45-50 minutes.
~4:00 PM
Back at Marina Santa Cruz. Captain docks, assists guests off. Balance payment in cash at the dock. Total time on the water: approximately 8.5 hours.

What to Bring on a Rosario Islands Boat Tour

The Rosario Islands are 35 km offshore with no convenience stores, limited shade, and COP-only payments at the park checkpoint. This list is based on what first-timers wish they had brought.

✅ Must-Have

  • COP cash for park fee — ~COP 25,000-28,000 per person (~$6-7 USD). No ATMs offshore.
  • Water shoes — Many Rosario Island beaches are rocky volcanic coral, not sand. Flip-flops are not enough.
  • Reef-safe sunscreen — Required inside the national park. Standard chemical sunscreens damage coral.
  • Dry bag or waterproof phone case — Open-bow lanchas get splash on rough crossings.
  • Food and drinks — Boat includes cooler and ice. No stores on most of the 27 islands.
  • Towels — Not provided. Bring at least one per person.

👍 Recommended

  • Seasickness medication — The channel can have 1-1.5m swells even in dry season. Take medication 1 hour before departure if prone to motion sickness.
  • Snorkel gear — Available as add-on from Nauty 360. Bring your own if you prefer your mask.
  • Underwater camera or GoPro — Coral reef visibility 8-15m. Worth it.
  • Hat and UV shirt — Open-water Caribbean sun is strong from 10 AM onward.
  • Small COP cash buffer — Some islands have informal food and drink vendors who only take COP.
  • Captain gratuity — Optional local standard: $25-50 USD for a full day.

When a Private Rosario Islands Charter Is Not the Right Choice

This is not the right trip if:
  • Your group is 1-3 people on a tight budget. Shared catamaran tours run $65-90/person including park fee. For 2 people a private lancha at $680 means $340/person — the math only works if guaranteed privacy matters more than cost.
  • You are visiting June through October. Rainy season brings swells above 1.5m, visibility drops to 3-5m, and your captain may legally reroute to calmer waters. If snorkeling is your primary goal, December-April is non-negotiable.
  • You expect half-day availability. The 35 km transit, the park checkpoint, and the 3:30 PM cutoff make this a full-day commitment. If your schedule doesn't allow 8 hours, consider Cholon (30-40 min away) or a bay sunset cruise instead.
  • You have severe motion sickness and haven't tested open-water crossings. The Rosario Islands channel can reach 1-1.5 meters of swell even in dry season. Take medication before departure.
  • You want all-inclusive with guided snorkeling and food provided. Nauty 360 provides the boat, the captain, and the access. Food and guided instruction are not part of the base charter — shared tour operators bundle these better at the cost of itinerary control.

Rosario Islands Boat Tour — FAQ

Plan for a full day — approximately 8-8.5 hours total. One-way transit from Marina Santa Cruz de Manzanillo takes 42-50 minutes by lancha. The DIMAR-enforced 3:30 PM departure cutoff and the park checkpoint stop add time on both ends. Charters departing at 7:30 AM arrive at the islands around 8:30 AM and return to the marina by 4:00 PM, giving approximately 6-7 hours on the water. Half-day is not viable for the Rosario Islands due to distance.
A private lancha (up to 12 guests) costs from $680/day. Large lanchas (10-12 guests) run $1,100/day. Catamarans for groups of 15-30 guests start at $1,800/day. All rates include DIMAR-certified captain, fuel, and safety equipment. Additional costs: national park entry fee (~$6-7 USD/person in COP cash) and optional snorkel gear.
Yes. The Rosario Islands are inside Parque Nacional Natural Corales del Rosario y San Bernardo. Foreign visitors pay COP 25,000-28,000 per person (~$6-7 USD) at a floating checkpoint buoy in the channel before Isla Grande. Card payment is not accepted — bring COP cash. Your captain handles the documentation and coordinates with the park ranger.
DIMAR (Dirección General Marítima) and Parques Nacionales Naturales enforce a 3:00-3:30 PM maximum departure from the islands for all commercial vessels. Caribbean afternoon swells in the Rosario Islands channel build to 1.5-2 meters between 3:00-5:00 PM. Every licensed operator must comply — this is Colombian maritime law, not a Nauty 360 policy.
Snorkeling visibility ranges from 8-15 meters during dry season (December-April) at outer reef sites near Isla del Pirata and Isla Grande's north side. Shallow coral gardens near Islote Santa Cruz offer 3-5 meter depth, ideal for beginners. Rainy season (June-October) drops visibility to 3-5m across all sites. Snorkel gear is available as an add-on — mention at booking.
Highly recommended. Unlike Playa Blanca, most Rosario Island shores are rocky volcanic coral — irregular, sharp, and uncomfortable to walk on barefoot or in flip-flops. Water shoes make moving around significantly more comfortable and protect against sea urchins in shallow reef areas.
December through April is optimal. During dry season, seas stay below 1 meter and coral reef visibility reaches 8-15 meters at the best snorkeling sites. June-October (rainy season) brings swells above 1.5 meters and reduces visibility to 3-5 meters. February and March offer the best combination of calm water and competitive pricing before the Easter surge.
