  • What to Bring: Sunscreen, hat, binoculars, camera, and anti-seasickness medication.
  • Ethical Practices: Choose operators maintaining a 100-meter distance from cetaceans and avoiding chases to reduce stress on animals.

Responsible Whale Watching and Conservation

Whale watching in Sri Lanka is thrilling, but unsustainable practices harm cetaceans. Issues include:

  • Ship Strikes: Large vessels in Sri Lanka’s busy shipping lanes (e.g., near Trincomalee) pose collision risks, especially for blue and fin whales.
  • Noise Pollution: Boat engines disrupt whale communication, affecting species like sperm whales that rely on echolocation.
  • Overcrowding: Too many boats in Mirissa can stress whales, causing avoidance behaviors.

Mirissa Jetliner is committed to conservation by:

  • Adhering to Whale and Dolphin Conservation Society (WDCS) guidelines, maintaining sympathetic distances.
  • Partnering with local conservation groups to monitor cetacean populations.
  • Educating tourists on sustainable practices to protect Sri Lanka’s marine life.
