Isla Perro, Perro Chico or Perro Grande? How to Tell Them Apart

Isla Perro is not one island but a small group of cays a short boat ride from Cartí. Perro Chico, called Assudub Bipii in Guna, is the small uninhabited one with the coral-covered shipwreck. Perro Grande is its larger, inhabited neighbour, with wide beaches and simple cabins. Isla Diablo and Nugnudub belong to the same group.

What “Isla Perro” actually refers to

Perro is Spanish for dog, chico for small and grande for big, and that is the whole logic of the names: two neighbouring cays told apart by size. The trouble starts when a tour listing, a review or a booking chat says only “Isla Perro”. Sometimes the writer means the whole group. Very often they mean Perro Chico, because the wreck is what people come for. Occasionally they mean Perro Grande, because that is where someone slept.

A second layer of confusion comes from maps. Some operators file the Perro islands under the neighbouring Cayos Limones, the cluster of uninhabited islets next door, and the overnight island tour does visit the two areas back to back. On this site we keep them apart, because the experience is different: Limones is about hopping between empty sandbars, the Perro group about one specific wreck and two islands with people on them.

The Guna names add a third layer. Every island here has one, and many have little to do with the Spanish. Perro Chico’s is Assudub Bipii. You will notice the ending dub across the archipelago: it means island, as in Gardi Sugdub or Nugnudub. Guides use the Guna names among themselves, so it helps to recognise them.

Perro Chico: the island with the wreck

Perro Chico is small enough to walk around in under ten minutes and nobody lives on it. Its fame lies a few strokes off the beach: a sunken vessel, resting in shallow water, that has turned into an artificial reef. Coral grows on the hull, and the structure gives reef fish the shade and edges a flat sandy bottom cannot, which is why the wreck holds more life than open sand nearby.

What this means in practice:

• It is a day stop, not a place to sleep. There is a strip of sand to dry off on and very little else.
• It gets busy. Because nearly every operator wants the wreck, several boats often coincide by mid-morning. An earlier arrival buys you clearer water around the hull.
• No diving is needed, or allowed. You float above the wreck with a mask; tanks are not permitted for visitors anywhere in Guna Yala, as our answer on scuba diving explains.

Perro Grande: the island with room

Perro Grande is the one whose size is the point. Most cays in San Blas are rings of sand you cross in a minute; this one has beaches wide enough that a boatload of visitors spreads out instead of sharing the same twenty metres. The water is calm and turquoise, better for slow swimming than for chasing fish.

It is also inhabited, and simple beachfront cabins host overnight guests. One detail matters when you plan: stays in San Blas are sold by cabin type, not by island, and the island is confirmed nearer the date. You can ask for Perro Grande; you cannot be guaranteed it. Our guide to overnight stays explains the five cabin types.

Isla Diablo and Nugnudub: the rest of the group

Two more islands sit in the same cluster, and both regularly get mixed up with the Perros.

Isla Diablo is a small, calm island with its own published day tour and simple Guna-run cabins. Its route includes a stop at a sandbar called the Starfish Pool, which is a different place from the Piscina Natural on the Classic and VIP itineraries. If a specific sandbar matters to you, name it.

Nugnudub is home to an active Guna community and is not a fixed stop on any itinerary. People who want to see an inhabited island rather than another beach ask for it in advance.

How to read a tour listing that just says “Isla Perro”

Ask three questions before you book:

1. Which island, exactly? Perro Chico for the wreck, Perro Grande for space, Isla Diablo for its own route.
2. Is the snorkel guided? The VIP day tour includes guided reef snorkelling at the wreck; the Classic itinerary does not include guided snorkelling.
3. Is gear included? Not on every tour, and a borrowed mask that leaks will cost you the stop.

Any operator who cannot answer the first question clearly is probably not sure where the boat goes either. Routes always depend on the weather and the day’s conditions, but the plan should be specific.

Frequently asked questions

Are Perro Chico and Perro Grande the same island?

No. They are neighbours in the same group, a short boat hop apart. Perro Chico is small, uninhabited and known for the shipwreck; Perro Grande is larger, inhabited and known for wide beaches and cabins.

Which island has the shipwreck?

Perro Chico. The wreck lies in shallow water just off its beach and has become an artificial reef that beginners can snorkel over from the surface.

Can I sleep on Perro Chico?

No. It is uninhabited and used only as a day stop. Overnight guests stay on inhabited islands such as Perro Grande or Isla Diablo, assigned according to the cabin type booked and availability.

Is Isla Diablo part of Isla Perro?

Yes, it sits in the same group, but it is a separate island with its own day tour and its own sandbar stop, the Starfish Pool.

What is Perro Chico called in the Guna language?

Assudub Bipii. Guides may use that name rather than the Spanish one, and dub, the ending shared by many island names here, means island.

Do all San Blas tours stop at Perro Chico?

No. The VIP day tour is the one built around the wreck, and overnight stays include it on the Day 2 island tour. Other itineraries may pass nearby without a guided snorkel there, so check before booking.
