I have been coming to Grand Marais for many years. And recently returned to tennis for the fun of it. On two occasions this summer (August and September) we stopped while in Grand Marais for the weekend to play a little tennis on these courts. We enjoyed great breezes (not too much, though) and very fine court conditions. We were pleasantly surprised to "discover" these. There are several courts - and a portable toilet (very clean when we were there), great parking.
