Try Kayaking, as it allows you to glide along the tranquil sea and absorb the pristine surroundings of your island paradise. This is a fun and calming activity, plus an awesome mini-workout! Most resorts will arrange the kayaking essentials for you. Use all fundamental safeguards like donning a life jacket and wearing a whistle. Also, wear good sunscreen, preferably coral-safe, to shield yourself from UV rays and sunglasses and a wide-brim hat to cut off the glare. Swimming skills can be helpful but not compulsory. Just don't undertake any risky excursions on your own, and stay within sight of the lifeguards on duty!
