Transportation in Sun Lakes State Park


Sun Lakes-Dry Falls State Park is accessed from Washington Route 17, which runs in a north to south manner. The drive from Coulee City is uneventful with little or no navigating problems if you are driving an RV or pulling a trailer.

If you are coming from Grand Coulee or Coulee Dam, you will need to drive along scenic Washington Route 155, which follows the shoreline of Banks Lake until you reach Coulee City and Route 17. Driving Route 17 to the park from the south is a little more difficult to navigate as the road traverses over and around several lakes. You will enter the park off of Route 17 onto Park Lane Road Northeast. Once inside the park, RVs and trailers will need to maneuver through several curves and turnoffs that lead to various places within the park before reaching the campground area.

The road to Dry Falls Lake is the longest drive and most difficult if you have a larger RV or trailer. If you are pulling a trailer, you may think about unhitching before making the drive on this road which has numerous curves and hairpin turns. The road to Deep Lake is an easier drive with fewer turns and the terrain is less undulating. There is also a road that will take you to the boat ramps at Park Lake.

An additional car or traveling by bike is preferred by most RVers and those pulling trailers. The main campground consists of seven loops which are connected by one two-way road that is narrow with curves for you to maneuver. The road out of the campground leads to Dry Falls Lake and can be congested at times during the high season with not only traffic but bicyclists too. Another road leads out of the main campground to an additional campground that contains campsites 58 through 88. If you are camping in the second campground you must stay to the left when the road branches off to Dry Falls Lake and the Umatilla Rock Trailhead.
