San Andrés, a Colombian island in the Caribbean Sea, is known for its beautiful beaches, coral reefs, and rich marine life, making it a popular destination for snorkeling and diving. The island offers a mix of relaxation and adventure, from exploring the vibrant town center to enjoying water sports. Accessibility is generally good in tourist areas, but some remote spots may present challenges. Solo travel is safe and common, while guided tours are available for exploring specific attractions like the Hoyo Soplador or El Acuario. The dry season (December to May) is the best time to visit, avoiding the rainy season. A typical visit lasts 3-7 days, with costs varying based on accommodation and activities, but generally considered mid-range. Expect to spend between $50-$150 per day, depending on your travel style.
