Cave Pool & Lava Tube Swims of Upolu: A Deep Dive into Samoa’s Natural Wonders

If you’re looking for a full-day adventure that combines swimming in pristine cave pools, exploring volcanic lava tubes, and soaking in spectacular waterfalls, the Cave Pool & Lava Tube Swims of Upolu tour offers just that. For $149 per person, you’ll spend roughly a day immersed in some of Samoa’s most extraordinary natural sights, guided by knowledgeable locals who know these hidden gems intimately. Led by Samoan Highland Hideaway & Adventures, this tour promises a mix of active exploration and relaxing swims — all packed into a well-paced itinerary.

What truly makes this experience stand out is the chance to swim in three distinct cave pools and lava tubes, each offering a different perspective on Samoa’s volcanic landscape. We especially loved the hidden entrance to Vaiula Cave Pool, accessible after a jungle hike, and the steep descent into the To Sua Ocean Trench, which takes you right into the heart of a volcanic crater filled with tidal waters. Plus, the view of Papua Papaitai Falls, measuring 110 meters, adds a scenic touch that caps off the day.

One possible consideration is the moderate physical activity involved, especially the jungle hike and steep descent into the trench. Travelers with mobility issues or those not comfortable with some bending or climbing might find parts of the tour a bit challenging. Still, if you enjoy a bit of adventure and are prepared for some wet conditions in caves, this trip is well worth your time.

This tour suits adventurous travelers who love authentic experiences and aren’t shy about getting a little wet and muddy. It’s perfect for those who want to combine swimming, hiking, and sightseeing into one memorable day, especially if you’re curious about Samoa’s volcanic landscape and love discovering lesser-known spots.
