Coming from I-90:
1.  Regardless which direction on I-90 you are coming from, take the Randall Rd. exit.  Randall Rd is west of the Fox river and the IL-31 exit as well as east of the US-20 exit by Hampshire.  Go north on Randall Rd. when exiting the highway.

2.  You will pass by Algonquin, Lake in the Hills, and then come to a Y intersection with a stop light.  If you are going to the lake, you need to take a left (use the turn lane) onto McHenry Ave.  If you are going to hotels in the Crystal Lake area, go straight on Rakow Rd. and continue to Rt. 31. 

Continue to the Lake
3.  Take McHenry Ave until you get to US-14 (Virginia St).  Make a left turn.

4.  If you have a boat trailer, you need to go through the next light (Dole Ave), then take a left onto Lake Shore Drive (see Landmark Map below for more detail).  Use both lanes to make sure traffic does not try to get around you while turning. All other visitors need to take a left onto Dole Ave.
