Dive down to explore thriving coral reefs, schools of tropical fish, and the serene silence of the ocean floor.

Sea walking is a rising trend, perfect for non-swimmers or those who want a unique underwater encounter. Wearing a specially designed helmet, you’ll walk along the seabed while breathing normally – no swimming required. Interact with friendly fish and marvel at colorful coral formations up close, all while staying dry from the neck up.

  • Warm up before diving to prevent cramps or muscle tightness in cold water.
  • Don’t dive on a full or empty stomach – wait at least an hour after eating.

  • If you feel unwell or notice any issues with equipment, signal your guide immediately.
  • People with heart or blood pressure conditions should consult a doctor before attempting diving.
