Longboarding Island Trail is a mellow cruise around an inner circuit of the island in Lake Havasu City. The paved trail is a bit short - clocking in at 3.6 miles - but it's a loop so there's no repetition of scenery like on an out and back. Unless of course you want to do a few laps. In addition to the perk of it being a loop, there are numerous areas where you can take a break from the hot desert sun and wander over to the waters edge to cool off.
