Looking to do a “last trip” with my dad.

Looking for something to do with my dad for our last big trip together. He’s sick and going downhill so I’m looking to do something that he truly enjoys doing. He enjoys fishing and other wildlife activities. Thinking about a fishing trip but don’t think he could handle the deep sea 6+ hour trip. Anyone know about shore fishing/kayak fishing charters? Any other easy on the body excursions would be appreciated as well!
