Three hand-reasoned picks from nearby campgrounds — one per reason you might prefer it over this spot.

If the source feels too commercial and pricey, Sheffield offers a primitive $13 site near the same parkway with bear lockers and fire rings.

If you want wilder and quieter: Lizard Creek sits on Jackson Lake with spacious sites and a more remote feel than the highway-adjacent Flagg Ranch.

If amenities matter more than location between parks, Colter Bay adds a marina, electric hookups, and lakeside Teton views with higher reviewer sentiment.
