Backpacking in Aunu’u Island Natural Reserve
👍 Recommendednational park ranked #3
By Johan Kruseman 🇳🇱 | Updated June 27, 2026

Your boots crunch on coral gravel, the air thick with salt and wet earth, and every step sends tiny red crabs skittering into pandanus roots while waves thud against the reef just out of sight. This is Aunu’u Island Natural Reserve, a small offshore island east of Tutuila in American Samoa, reached by a short local boat ride that feels longer when the seas are rough. For backpackers, it’s a low-key, low-infrastructure stop: short but satisfying coastal and crater-lake walks, lush jungle, seabirds, and that “you’re really out here” isolation. There’s no entrance fee, but also no real camping or budget stays on the reserve itself, so you base on Tutuila and day-trip in, which limits sunset time but keeps logistics simple. Compared with the bigger units of National Park of American Samoa on Tutuila and Ofu, Aunu’u is smaller, muddier, less dramatic, but more intimate and very, very local.

💡 HighlightsWhat this place is best known for

  • Crater lake (Aunu’u Crater) — A shallow freshwater/brackish lake sitting inside a volcanic crater; it’s the island’s green heart and a peaceful spot for birdwatching and short rim walks. The contrast of blue water and steep walls is striking in photos.
  • Wetland and taro patches — The low-lying marshes around the crater are still used for traditional taro cultivation and support a mosaic of wetland plants you won’t see on the dry coast. Quiet, slow-moving, and full of small wildlife signs.
  • Seabird rookeries — Rocky shorelines and cliff ledges host nesting seabirds (think terns and boobies). Bring binoculars: you can watch nesting behavior without getting in the birds’ way.
  • Coastal viewpoints and short hikes — There aren’t long, rugged trails here, but the short walks along the rim and shore

  • Coastal viewpoints and short hikes — There aren’t long, rugged trails here, but the short walks along the rim and shore deliver dramatic views across the lagoon and toward Tutuila. Great for sunset photo stops and easy exploration.
  • Fringing reefs and snorkeling — Clear, shallow reefs just off the island hold colorful reef fish and healthy coral patches. Snorkel from a protected bay for a low-effort wildlife encounter.
  • Quiet beaches and tidepool exploring — Small sandy pockets and rocky platforms make for relaxing beach time; tidepools reveal crabs, small fish, and interesting invertebrates at low tide.
  • Village life and cultural landscape — Aunu’u’s tiny village and cultivated plots give a real sense of local Samoan life: traditional fale, fruit groves, and welcoming locals. It’s as much a cultural visit as a nature one.

🌤️ When to go?Best time to explore Aunu’u Island Natural Reserve


  • Weather: The dry season from May to October offers the most reliable conditions for backpacking. Expect less rain, which means trails are safer and less slippery. The wet season (November to April) brings heavy showers and occasional cyclones, which can disrupt plans and damage paths.

  • Temperature: Temperatures hover between 24°C and 29°C (75°F to 85°F) year-round. Humidity spikes during the wet season, making the heat feel more oppressive. The dry months provide a more comfortable balance for hiking and camping.

  • Daylight Hours: Daylight remains fairly consistent, roughly 11 to 12 hours daily. However, the dry season’s clearer skies mean more usable daylight without the interruption of afternoon storms.

  • Crowds: Aunu’u Island Natural Reserve sees very few visitors year-round, but the dry season attracts slightly more locals and tourists. You won’t face crowds, but expect a bit more activity during peak dry months.

  • Seasonal Activities: Wildlife spotting and snorkeling are best in the dry season when water visibility improves. The wet season can limit these activities due to rough seas and murky water.

  • Price Fluctuations: Accommodation and transport costs remain stable year-round due to the remote location. However, booking during the dry season might require more lead time as demand rises slightly.


Pro-tip: Aim for late May to early July—this window balances dry weather, manageable crowds, and optimal wildlife activity, saving your energy and budget for the real adventure.
