Those are all wonderful suggestions, but be careful what you recommend. Horseback riding along Negril's beach in any form or fashion is strictly illegal and the Police will stop that activity if they are present. It is better to stay with fully licensed and insured horseback riding operations. Likewise, spearfishing is illegal in most places where fish are present, especially in proximity to any reef or marine park. Line fishing or deep sea fishing is preferable. Jet-ski's are also carefully regulated as they are very unfriendly to the environment..
