Santa Fe Island, Galapagos: Travel Guide (2025)

Santa Fe Island, a volcanic gem in the Galapagos Islands, is famed for its giant Opuntia cacti, turquoise bays, and the endemic Santa Fe land iguana. This guide covers snorkeling hotspots like Barrington Bay, hiking trails, and ongoing efforts to protect its fragile ecosystem.

Santa Fe Fast Facts

• Nickname: “Land of Giants” (giant cacti and iguanas).
• Unique Species: Home to the Santa Fe land iguana (Conolophus pallidus).
• Size: 24 km² (9.3 sq mi), one of the oldest islands (4 million years).
• Visitor Site: Barrington Bay, a sheltered cove for snorkeling and kayaking.
• No Permanent Residents: Only park rangers and guided tours allowed.

Santa Fe Activity Highlights

• Hiking to Santa Fe’s Viewpoint: Panoramic vistas of Barrington Bay and Opuntia forests.
• Snorkeling with Sea Lions: Playful pups at Barrington Bay.
• Kayaking Along Coastal Cliffs: Spot Galapagos hawks and marine turtles.
• Photographing Giant Opuntia Cacti: Some reach 10m (33ft) tall.
• Birdwatching for Darwin’s Finches: Unique subspecies adapted to arid climates.

Santa Fe Animal Highlights

• Santa Fe Land Iguana (Conolophus pallidus): Yellowish, larger than other iguanas.
• Galapagos Hawk (Buteo galapagoensis): Apex predator nesting on cliffs.
• Galapagos Sea Lion (Zalophus wollebaeki): Colonies bask on white-sand beaches.
• Rays: Golden cownose rays (Rhinoptera steindachneri) glide in shallow bays.

History

• Volcanic Origins: Formed 4 million years ago, Santa Fe’s flat terrain contrasts with steep cliffs.
• Whaling Stopover: 18th-19th century whalers collected giant tortoises for food, wiping out the island’s native population. 2015 saw the reintroduction of tortoises to the island.
• Scientific Studies: Researchers track Opuntia cactus growth to understand climate resilience. They have also been keeping track of black rat and red ant infestations over the years to preserve the native rice rat population.

Geography

• Size: 24 km² (9.3 sq mi), with a maximum elevation of 259m (850ft).
• Key Features: Barrington Bay (turquoise lagoon), Punta Varillas (sea lion haul-out site).
• Vegetation: Opuntia cactus forests, palo santo trees, and saltbush scrubland.

Getting to Santa Fe Island

Accessible via day tours from Santa Cruz Island (2-hour boat ride) or multi-day cruises. No airports or mainland ferries access the island.

Conservation Challenges

• Invasive Species: Feral goats (finally eradicated in 1974) once destroyed cactus habitats. Scientists continue to monitor for the presence of black rats. 
• Climate Stress: Droughts on the Galapagos Islands threaten Opuntia cacti, a critical food source for iguanas.
• Tourism Impact: Foot traffic compacts soil; designated trails now limit erosion.
• 2025 Coral Monitoring: Scientists track reef health in Barrington Bay (and elsewhere in the Galapagos Islands)  using a variety of methods.

Economy

• Tourism: Licensed guides lead visits; fees fund iguana conservation.
• Research: Grants support studies on the vegetation and animals on the island.

Climate

• Dry Season (June–November): Cooler, windier (20–25°C / 68–77°F), ideal for hiking.
• Wet Season (December–May): Warmer water (24–28°C / 75–82°F) for snorkeling.

• Lava Heron (Butorides sundevalli): Strikes fish with lightning speed in tidal pools.
• Galapagos Dove (Zenaida galapagoensis): Trusting doves with blue eye-rings forage near trails.
• Darwin’s Finch (Geospiza spp.): Look for the cactus finch (Geospiza scandens) probing cacti for insects.
• Yellow Warbler (Setophaga petechia): Bright yellow birds flit through saltbush thickets.

Fish & Underwater Life

• Golden Cownose Ray (Rhinoptera steindachneri): Glide in groups of 20+ over sandy bottoms.
• White-Tipped Reef Shark (Triaenodon obesus): Rest in caves during the day; harmless to snorkelers.
• Eagle Ray (Aetobatus laticeps): Wing spans up to 2m (6.5ft); often seen in Barrington Bay.

Travel Tips and Practical Information

• Permits: All visitors to Galapagos need to pay the Galapagos National Park entry fee ($200 for most adults). Additionally, all visitors to the Galápagos must obtain an INGALA Tourist Control Card (TCT).
• Gear: Pack reef-safe sunscreen, a UV-protective shirt, and hiking shoes/sandals.
• Safety: Avoid touching cacti (spines) and maintain 2m (6.5ft) from wildlife.
• Currency: USD is Ecuador’s currency; cash is essential for tips.
• Motion Sickness: Take motion sickness medication beforehand; the approximate 2-hour navigation from Santa Cruz can be choppy.
