Grassy Lake Road dispersed camping offers free sites located approximately 7 miles from the main highway between Yellowstone and Grand Teton National Parks. The area requires navigation along a gravel road that becomes washboarded in sections but remains accessible to most passenger vehicles during summer months. Camping areas are typically accessible from mid-June through early fall, with road closures common during winter and spring due to snow and seasonal conditions.
What to do
Fishing opportunities: Several campgrounds provide direct access to streams and rivers for fishing. At Snake River — Yellowstone National Park, campers report excellent fishing conditions. "The snow capped mountains, the hot springs river runoff that joins the snake river, the fishing that was incredible, the peace and quiet- WOW," notes Daniel P.
Hiking nearby trails: Access numerous hiking trails directly from camping areas. At Pacific Creek (FR 30090) Designated Dispersed Campsite, campers find "a campground a bit farther down the road" with "lots of hiking," according to Cmezz U. The surrounding area offers trails for various skill levels.
Stargazing after dark: Clear skies provide excellent night viewing opportunities away from light pollution. One camper at Ashton-Flagg Ranch Road noted that "camps have beautiful views and the night sky glows," making it ideal for astronomy enthusiasts.
What campers like
Bear-resistant food storage: Many sites include secure storage for food and supplies. At Snake River Dispersed - Rockefeller Memorial Parkway, "each designated site has a bear box," providing essential safety for all campers. Lauren B. confirms, "bear boxes at every site."
Proximity to national parks: Locations provide convenient access to both Grand Teton and Yellowstone. A visitor at Upper Teton View noted the area was "great for the nights we were visiting Grand Tetons National Park" and that it's "only about 30 mins from my first stop at Grand Tetons."
Stream and river access: Many sites border water features with creek and river sounds. At Pacific Creek, Connor Y. reported, "Great access to and views of the river and it's nice and secluded. Would definitely stay here again."
What you should know
Limited site availability: Competition for free camping near John D. Rockefeller Jr. Memorial Parkway intensifies during summer months. At Shadow Mountain Dispersed Camping, "We arrived around 2PM on our first day and all sites were full, we came back around 8 the next morning and found one site available for us to take," according to Ryan L.
Insect activity: Mosquitoes and biting flies can be problematic in summer months. At Pacific Creek, Katie J. reported, "The mosquitoes were atrocious, but I expected it in woods this heavy, and for as much rain as Wyoming has gotten this year."
Variable road conditions: Access roads range from well-maintained to challenging depending on weather and location. Alexandra B. noted that at Pacific Creek there are "8 sites" but the roads can be challenging with "several miles of washboard road to reach the site."
Tips for camping with families
Early arrival strategy: Plan to secure sites by early afternoon, especially during peak season. At Grassy Lake Dispersed Camping, one camper noted, "We had to drive super far to find a spot to stay. But we got lucky."
Wildlife viewing opportunities: Morning and evening provide the best wildlife sightings. Ivan C. at Ashton-Flagg Ranch Road recommended "Oxbow Bend to catch the sunrise" as a prime viewing opportunity.
Pack additional supplies: Due to distance from services, bring extra provisions. John T. at Pacific Creek emphasized the remoteness: "Several miles of washboard road to reach the site. Camped along the stream, very pretty. There is a bear box and fire ring at the site."
Tips from RVers
Site selection for larger vehicles: Choose appropriate sites based on rig size and road conditions. Chuck S. at Upper Teton View advised: "Road up is a little rough but made it fine towing our 38ft 5th wheel. Views are amazing and probably none better in the Tetons when camping for free."
Bear safety precautions: Always use available bear boxes and follow proper food storage protocol. Andrew G. described Ashton-Flagg Ranch Road campsite amenities: "Each pull-off has 1 toilet and 1 trash, but has a firepit, table, and bear box for each designated camping spot."
Leveling challenges: Bring leveling blocks as many sites have uneven terrain. Lee S. at Pacific Creek shared, "We decided to pull our 29' travel trailer only partway into the space to find the most level spot."
