One question that we get asked very often by those wanting to visit the Galapagos Islands is a question about whether it is best to visit the west islands or the south islands of the archipelago. Few cruises cover both the southern and the western islands, so visitors find that they are usually in a position where they have to choose between one or the other. Indeed, only two or three Galapagos Islands cruises coverboth west and south islands in eight days. While there are similarities between the islands there are also differences. Here we will explain both the similarities and differences so you can get a better idea of what is on offer, and what you might expect on each.
Wherever you visit in the Galapagos Islands, the sorts of activities you undertake will be very similar. These will include hiking along pre-defined trails at land-based Galapagos visitor sites and snorkeling either from the beach, or at a marine site further out from the main islands. You’ll be likely to see much of the same wildlife wherever you visit. Highlights of trips to both sets of islands will often include seeing the Galapagos penguin, sea lions, blue footed booby, frigate birds and marine and land iguanas. You also have a good chance of seeing flamingos on both types of ruises, depending on the specific visitor sites you’re your cruise stops at. However, the places that you visit will vary significantly. Below the different types of itineraries are explained.
The western islands have itineraries that focus on visitor sites on Isabela Island and Fernandina Island. Fernandina Island is one of the furthest west in the archipelago and is also one of the youngest. It has less vegetation than some of the other commonly visited islands, but this does not equate to a lack of wildlife. Wildlife you could see on Fernandina includes the flightless cormorant, Galapagos penguin, blue footed booby, sea lion, fur seal, Sally Lightfoot crab, snakes and the Galapagos hawk. The main Galapagos visitor sites here include Espinosa Point and Mangle Point.
Isabela Island is a western island that is slightly further east than Fernandina. Cruises to the west islands often crisscross the channel between the two islands to see the different species and visitor sites on each. As Isabela Island you might see penguins, cormorants, boobies, Galapagos dove, Galapagos hawk, marine iguana, land iguana and giant tortoise. Commonly visited sites on Isabela Island include Tagus Cove, Puerto Villamil, Urbina Bay, Elizabeth Bay, and the Sierra Negra volcano. Some cruises may also visit Vicente Roca Point and Moreno Point.
The south island itineraries tend to visit Española Island, Floreana Island and often San Cristobal and sometimes some of the other centrally located Islands too. Española Island is the furthest south in the Galapagos Islands. The main visitor sites are Gardner Bay, and Suarez Point. Gardner Bay is a fabulous stretch of white sand beach, which is great for snorkeling and relaxing, while Suarez Point boasts a wealth of Galapagos birdlife including the waved albatross, and a stunning blowhole which is fascinating to watch.
On Floreana Island, there are various points of interest. One of these is the green tinged beach at Punta cormorant, where it is possible to see flamingo, Sally Lightfoot crab and green sea turtles. Post Office Bay with its antiquated postal system, still in operation today is another common visitor spot on this southern island. Nearby to Floreana Island is the Devil’s Crown visitor site, which is a marine site based on the area of an underwater volcano. It is considered one of the best spots for snorkeling in the islands, and there are chances to see sharks and pretty reef fish, as well as turtles and sea lions.
It is important to note that while most cruises focus on a single region, others are planned to include a broader mix of islands and ecosystems. Cruises like the Natural Paradise Galapagos Cruise, for example, are known for offering multi-region itineraries, which appeal to travelers who want maximum diversity in landscapes, wildlife, and activities within one voyage.
The main differences between the south islands and the west islands in the Galapagos archipelago are the landscapes you will experience. There are some differences in wildlife too, since some creatures can only be found in certain places.
For example, if you are set on seeing the waved albatross during your visit to the Galapagos Islands, you will want to book onto a cruise of the southern islands. This is because this unusual bird can only be found on Espanola Island which is in the south group of islands and visited on southern itineraries. Please beware that the waved albatross is not resident all year around, so the best chances of seeing it are between April and December. Also, red footed boobies are only seen in the south islands and will not be seen in the west. Mostly they are located on Genovesa Island and San Cristobal Island.
On the other hand, the flightless cormorant can only be found in the west islands of the Galapagos, namely, Isabela Island and Fernandina Island. This bird is unique to the cormorant family in that it cannot fly, which makes it interesting to see. It also of course means that the bird cannot fly to any other location, so it is limited in where it may be seen. In addition to this you have a greater chance of seeing whales and dolphins in the seas around the west islands, and there is also a higher likelihood of spotting a giant tortoise in its natural habitat in these islands. The landscapes in the western islands in general were formed more recently than the south, and there tends to be more volcanic activity to the west. This makes the west islands more geologically interesting for a visit.
It comes down to who you are. Eastern (Santa Cruz, San Cristóbal, Española, Floreana) is the right route for around 70% of first-time visitors — calmest seas, blue-footed boobies, waved albatross from April through November, and the most dependable family wildlife. Western (Isabela, Fernandina, Santiago) is the wildlife-photographer route — Galapagos penguins, flightless cormorants, dense marine-iguana colonies, and August–October whale-watching — but the Bolívar Channel between Isabela and Fernandina is the roughest water in the archipelago. Northern (Genovesa, Darwin, Wolf) is the diver's route, and most travelers see Genovesa as a 1–2-day add-on inside a longer Eastern loop, not a stand-alone trip. Full-archipelago (11–15 days) stitches two routes together for photographers, retirees, and anyone who has wondered whether the extra days pay off. They do, if you have the time.
We book Galapagos cruises across 40 vessels in 2026, spanning Eastern, Western, Northern, and full-archipelago routes. The route mix matters more than the raw vessel count. Eastern is the one we book most. Western pulls the wildlife-density travelers, and Northern (Genovesa) almost always rides along as an extension on a longer itinerary rather than a trip of its own.
The four routes are not interchangeable. They differ on sea conditions, signature wildlife, length, family-fit, and price band — and the difference is not marginal. Pick the wrong one for your trip and you'll have a great holiday, but you won't see what you came to see.

Every Galapagos cruise itinerary is approved by the Galapagos National Park and rotates on a fixed 14-day cycle. No vessel sails the same itinerary every week. The park assigns each licensed vessel a fortnight schedule — for example, weeks 1 and 3 sail one Eastern variant and weeks 2 and 4 sail another. The full register of approved itineraries is public.
Two reasons. First, visitor-site protection — the park caps daily visitors at every site, and the Charles Darwin Foundation tracks compliance. Second, even spread of demand — a site like Punta Suárez can't host every vessel every Tuesday morning. The rotation is what keeps the wildlife-encounter quality high. It's also what makes the booking process counter-intuitive for first-time visitors.
You don't pick "Eastern." You pick a vessel and a date, and the vessel's park-assigned itinerary for that fortnight tells you the route. We map every booking to its actual island sequence so you know what you're getting before you pay. Occasionally an operator swaps one or two sites mid-cycle — weather, a mechanical issue, park direction. We disclose those swaps when they happen, and we don't pretend they don't.
"The most common misconception we correct about 8-day cruises is that they 'cover everything.' Travelers come to us thinking one week is enough to fully experience both the western highlights like Fernandina and the more central or southern sites like Floreana. The reality is, no single 8-day itinerary does it all without trade-offs. In 2025 we worked with a couple who chose a 'combined' route, only to realize afterward they'd missed key sites like Punta Espinoza. Now we're very upfront — if you want both regions done properly, you're looking at back-to-back cruises or at least 11–15 days. Eight days is amazing, but it's curated, not comprehensive."
— Marcelo Guerrero, Co-Owner, Galapagos Insiders
The boats that advertise "both routes in 8 days" do it by skipping the best landing on each side. The park doesn't approve a combined Eastern + Western route inside 8 days, full stop. If you want both, book 11 or 15 days and do it properly.
Most pages gloss over this. We'd rather explain how the park works first, then show you where your trip fits inside it — because once you understand the rotation, the whole booking process stops feeling like guesswork.
In some cases, your choice of trip will be based around specific wildlife that you want to see, such as the waved albatross or the flightless cormorant, and in this case, this will dictate the itinerary you choose, whether west or south. In other cases, you may not have any particular preference. In these situations, it may be best to look availability and consider the types of deals you are being offered. Given that the western islands are a bit further afield, they may feel somewhat less visited, but visits to the islands are highly controlled, so it will never feel particularly crowded whenever you go.
