The Galápagos Islands are one of the few destinations on earth that genuinely live up to their reputation — a volcanic archipelago 1,000 kilometres off the Ecuadorian coast where blue-footed boobies dance on lava rocks, marine iguanas swim through tide pools, sea lions doze on park benches, and giant tortoises plod through the highlands of Santa Cruz with the same lack of urgency they brought to Darwin's notes in 1835. But the Galápagos also operate on a logic unlike anywhere else: a USD 200 park fee is mandatory, the island geography is real (you cannot just rent a car and explore), every visit requires advance permission via the INGALA card, the inter-island ferries are uncomfortable open-sea crossings, and the rules around protected zones are strictly enforced. First-time visitors who arrive informed have an exceptional trip; those who arrive expecting a typical Caribbean island holiday are repeatedly surprised. This guide walks through everything you need to know before flying — the fees, the airports, the islands, the etiquette, and the specific mistakes that derail most first-timers.
Before You Arrive
You enter the Galápagos as a tourist via Ecuador, and the entry rules for Ecuador apply. Citizens of the United States, Canada, the United Kingdom, the European Union, Australia, New Zealand, India, and most South American nations enter Ecuador visa-free for 90 days. Your passport must be valid for at least six months beyond your entry date. There is no entry fee at the mainland Ecuador airport, but there are two mandatory Galápagos-specific fees you must budget for separately.
The INGALA Transit Card (USD 20) is purchased before boarding your flight to the Galápagos at Quito UIO or Guayaquil GYE airports — there's a dedicated counter near the Galápagos check-in desks. You fill out a short form, pay USD 20 cash, and receive a card that authorises your visit. Without it you cannot board the flight. The Galápagos National Park Entry Fee (USD 200 for foreign adults, USD 100 for foreign children under 12) is paid in cash on arrival at Baltra (GPS) or San Cristóbal (SCY) airport. No credit cards. Have clean USD bills ready.
Ecuador uses the US dollar as its official currency. Galápagos ATMs are limited and unreliable — bring USD 600-1,200 in cash from the mainland, depending on trip length and whether you'll book day-tours on the islands. ATMs in Puerto Ayora exist (Banco Pichincha, Banco del Pacífico) but charge USD 5-10 per withdrawal and frequently run out of cash, particularly on weekends and holidays. Always carry small bills — taxi drivers and hostal owners cannot break a USD 100.
For SIM cards, Claro and Movistar both work in the Galápagos with reduced coverage compared to the mainland. A USD 5-10 prepaid SIM purchased in Quito works on Santa Cruz and San Cristóbal in the populated zones; coverage drops to nothing on the open ocean and most of Isabela. Do not rely on data for navigation between islands.
Pack for warm tropical weather year-round (24-30°C daytime), but expect significant variation between the dry/cool season (June-November, with light drizzle and stronger winds) and the wet/warm season (December-May, with afternoon showers and hot still days). Essentials: high-SPF reef-safe sunscreen, a wide-brim hat, polarised sunglasses, lightweight long-sleeve sun shirts, sturdy water shoes for tide pools and rocky beaches, motion-sickness medication (Dramamine, Gravol, or scopolamine patches) for the inter-island ferries, and a refillable water bottle. The UV at the equator is brutal — even short walks burn unprotected skin.
If you wear glasses, bring a backup pair — there are no optometrists on the islands. Same applies to any prescription medication. Bring snorkel gear from the mainland (USD 25-40 for a mask, snorkel, and fins set) — Galápagos rentals are USD 8-12 per day and shop hours are inconvenient.
Getting from the Airport
The Galápagos has two airports for international and Ecuadorian-domestic flights, and which one you arrive at determines your first day's logistics dramatically.
Baltra Airport (GPS) serves Santa Cruz, the most populated island and the typical first stop for most visitors. Baltra is on a small uninhabited island just north of Santa Cruz, requiring a free shuttle bus (5 minutes) to the Itabaca Channel ferry crossing, a USD 1 ferry across the channel (5 minutes, runs continuously), and then either a USD 5 public bus (45 minutes) or a USD 25-30 shared taxi to Puerto Ayora on the south coast. The whole journey takes 60-90 minutes. The public bus is comfortable enough and the shared taxi is faster — neither is a bad choice.
San Cristóbal Airport (SCY) serves Puerto Baquerizo Moreno, the provincial capital and a quieter, more relaxed alternative to Puerto Ayora. The airport sits a 10-minute walk or USD 2 taxi from town. There are no ferries or buses to navigate — you arrive, claim your luggage, pay the park fee, and walk into town. By far the easier arrival.
If you have a choice of arrival airport, San Cristóbal is the easier first day; Santa Cruz is the better hub if your overall plan involves multiple islands. Many travellers do a one-way arrival (e.g., GPS arrival, SCY departure) to avoid backtracking.
On arrival, the sequence is: disembark, INGALA card check, USD 200 park fee paid in cash at the dedicated counter, baggage claim with agricultural inspection (luggage is X-rayed and dogs sniff for prohibited fresh produce), then exit. Allow 45-60 minutes for the entire airport process.
Getting Around the City
Within each Galápagos town — Puerto Ayora, Puerto Baquerizo Moreno, Puerto Villamil — everything is walkable. The towns are small (Puerto Ayora is the largest at about 12,000 residents, with most tourist services concentrated within a 1-kilometre stretch along the harbour). You'll walk almost everywhere within town.
The interesting transport question is between islands and between towns and the wilderness areas.
Inter-island ferries (lanchas) connect Santa Cruz, San Cristóbal, and Isabela twice daily — typically 7am and 2-3pm in each direction. USD 30-35 per person per leg, 2-2.5 hours per crossing. Tickets sold at the harbour kiosks the day before; reservations not strictly required outside peak season but advisable. The boats are small (30-40 passengers), open Pacific water is involved, and seasickness is common — see the medication note above.
Water taxis within Puerto Ayora harbour cross to the dive boats moored on the western shore and to the Las Grietas trailhead. USD 0.80-1 per crossing, runs continuously dawn to dusk. Useful and cheap.
Public buses on Santa Cruz run from Puerto Ayora to the highlands (for the giant tortoise reserves at El Chato and Rancho Manzanillo) for USD 2-3 each way. Schedules are loose — check at the bus stop on Avenida Padre Julio Herrera.
Bicycle rental on Isabela (USD 3-5 per hour, USD 12-15 per day) is the standard transport for reaching the Wall of Tears, the flamingo lagoons, and the beaches outside Puerto Villamil. Flat terrain, short distances, sea breeze.
Taxis on the islands are mostly white Toyota Hilux pickup trucks. Within Puerto Ayora most journeys are USD 1-3; airport transfer to Baltra costs USD 18-25 one-way. Always agree the price before getting in.
Where to Base Yourself
The Galápagos has three islands with proper tourist infrastructure: Santa Cruz, San Cristóbal, and Isabela. Each has a different character and the choice (or sequence) shapes your trip.
Santa Cruz (Puerto Ayora) is the largest tourist hub, the central transport node, and the island where most day-tour operators are based. Tortuga Bay (one of the Pacific's most beautiful beaches), Las Grietas (a swimmable lava-rock canyon), the Charles Darwin Research Station, the highland tortoise reserves at El Chato and Rancho Manzanillo, and direct ferry access to North Seymour, Bartolomé, and the Plazas islets via day tours all originate here. The trade-off: it's the most touristy island, the most expensive, and lacks the small-town charm of the others. Most first-timers spend the largest share of their trip on Santa Cruz.
San Cristóbal (Puerto Baquerizo Moreno) is quieter, more relaxed, less developed, and home to the largest sea lion colony in the inhabited zones — sea lions sprawl across the malecón and town benches in numbers that border on absurd. Playa Mann, La Lobería, and the Cerro Tijeretas (Frigatebird Hill) trail are all walkable from town. San Cristóbal is the right choice for travellers who want a slower pace, more authentic local feel, and excellent free wildlife encounters. Fewer day-tour options than Santa Cruz.
Isabela (Puerto Villamil) is the largest island geographically but the least developed for tourism — a small village, sand streets, flamingo lagoons just inland, the Sierra Negra volcano hike, and arguably the best snorkelling sites (Los Tuneles, Las Tintoreras) in the populated archipelago. Slower pace than Santa Cruz, fewer services than San Cristóbal, but the most rewarding for travellers who already have basic island orientation and want a quieter base. The ferry crossing from Santa Cruz to Isabela is the roughest of the inter-island routes.
Local Culture & Etiquette
The Galápagos has a unique cultural mix — about 30,000 permanent residents, mostly Ecuadorian mainland-origin (many from Loja and Manabí provinces), plus a small population descended from the original Norwegian and German settlers, and a steady flow of national park staff and naturalist guides. The culture is overwhelmingly conservation-focused, and tourism etiquette here is taken seriously.
Maintain distance from wildlife. The Galápagos National Park rule is two metres minimum from any animal. The rule exists because the wildlife has no fear of humans — sea lions will lounge on benches you want to sit on, marine iguanas will sun on paths you want to walk, and giant tortoises will block trails — but the proximity must be one-way. Do not touch any animal under any circumstances. Do not feed any animal. Do not block their path. Do not flash photography on nesting birds. Naturalist guides will warn you once; persistent violations result in tour expulsion.
Stay on marked trails. The visitor sites within the national park have marked paths, and stepping off the path is genuinely a finable offence. The reasoning is ecological — invasive seeds carried on shoes can devastate native plant populations on the smaller islands. On every populated zone trail (Tortuga Bay, Las Grietas, La Lobería), follow the boards.
Pack out everything. Plastic waste is a real problem in the Pacific, and the Galápagos enforces a strict pack-it-out culture — no rubbish bins on most beaches and protected sites. Bring a small dry-bag for your snacks, drinks, and sunscreen waste, and dispose of it at your accommodation.
Greetings matter. Like the Ecuadorian mainland, basic greetings ("buenos días", "buenas tardes") significantly improve interactions with shopkeepers, taxi drivers, and tour staff. Most guides speak some English but the warmth multiplies when you make even modest Spanish efforts.
Tipping for guides is expected — USD 5-10 per person per day for day-tour naturalists, USD 50-150 per passenger for cruise guides at the end of a multi-day cruise. Hotel and hostal staff tipping is modest (USD 1-2 per service). Restaurants automatically include 10% service plus 12% IVA on the bill.
Photography of the wildlife is fine; photography of local people, particularly children, requires asking first. The conservation staff and park rangers are typically happy to be photographed in uniform if asked politely.
Common Mistakes to Avoid
1. Booking your Galápagos cruise online from abroad at full price. Cruise prices are 30-60% above the rates available in Quito (at agencies on Avenida Amazonas) or in Puerto Ayora (at agencies on Charles Darwin Avenue) within five to seven days of departure. The structural reason: cruise operators have empty cabins to fill at the last minute and discount aggressively. If you can be flexible on dates and willing to book on arrival, you save USD 800-2,500 on a typical 5-8 day cruise. Book online only if your dates are inflexible and you cannot afford last-minute risk.
2. Underestimating the cash requirement. First-timers routinely arrive with USD 200-300 in cash and discover that the park fee alone (USD 200) plus INGALA (USD 20) consumes almost all of it before they've eaten lunch. Bring USD 600-1,200 from the mainland, in clean USD bills, in a money belt. The Galápagos ATMs cannot be relied on as a backup.
3. Ignoring the seasickness on inter-island ferries. "I don't get seasick" is a common pre-Galápagos belief that the open-Pacific ferries quickly disprove. Take Dramamine 30 minutes before boarding regardless of your normal tolerance. Travellers who skip this routinely vomit during the 2.5-hour crossings, which ruins both the day of the crossing and often the next morning's planned activity.
4. Spending too long on Santa Cruz. Santa Cruz is the largest tourist base but also the most touristy, expensive, and least authentic. First-timers who spend their entire trip on Santa Cruz miss the sea-lion-saturated charm of San Cristóbal and the wilder feel of Isabela. Three nights on Santa Cruz is plenty for most itineraries — push the additional time toward Isabela in particular.
5. Approaching wildlife for photos. The two-metre distance rule is real and enforced. Approaching a sea lion to get a closer shot, or trying to pose next to an iguana, will get you a public scolding from your naturalist guide and, in repeat cases, expulsion from the tour without refund. The wildlife is so unconcerned by humans that you can get spectacular photos from the legal distance with any standard camera or phone.
6. Not booking the popular day-tours far enough ahead. The premium day-tours — Bartolomé Island, North Seymour, the Plazas islets — sell out 2-4 days in advance in peak season. Visit the agency on your first day in Puerto Ayora, look at the available dates, and book before the spots vanish. The cheaper local tours (highlands, Las Grietas) can be booked the day before.
7. Assuming the Galápagos is a Caribbean-style beach destination. The Galápagos is a wildlife destination first and a beach destination second. The water is colder than expected (the Humboldt Current keeps it 18-23°C even at the equator), the beaches are wild rather than resort-lined, and the activities revolve around walking, hiking, snorkelling, and wildlife observation rather than lying on a sun-lounger with a piña colada. Travellers expecting Cancún are repeatedly disappointed; travellers who arrive prepared for nature-first leave thrilled.
