My 50 year old parents and I did a Stand Up Paddle lesson. First time any of us had surfed or been on a board! We tried some boogie board a few days before, we were awful. We all stood up on the paddle boards, but my dad took a tumble and was content to stay on his knees for the rest of the lesson. A couple of us even rode some of the smaller waves like a surfer! If my parents can get past their bad knees and SUP for the first time, then I'm sure a huge variety of people are capable of it! It is very taxing on your ankles and knees, that's where all the balance comes from. Taylor was great, switched out our boards when one of us was struggling standing. Lots of tips on shore that we put into practice for the next hour and a half. Perfect amount of time for a lesson. I think this is the best value of any Maui activity we did on this trip. $80, comes with 100+ photos from their photographer from shore, a hat, and discounts on future rentals.
