The Hobby Garden is a great place for families and school groups to spend a fun afternoon while maybe learning a thing or two. The place is run by an amazing and talented man named Johnson Lum. This is a non-stop project of his so you can go again and again to find new things each time. There is a man-made lake which has catfish and tilapia. You can feed the fish or catch and release them using his poles. No waves to knock you off the rocks. There is a 9-hole mini golf putting course, basketball hoop shooting, exercise machines, video gaming center and even a riding railroad for the younger kids. There are three humongous tables with model trains and all kinds of exhibits including a glowing/smoking volcano, the great pyramids, Golden Gate Bridge, Eiffel Tower, Great Wall of China and much more.  Admission price is just $5(adults) and $2.50(children).  He has group discounts also. Located in Hawaiian Paradise Park about 20 minutes from Hilo.
