The dog-friendly Jackson Hole trail will take you to three pools / swimming holes. The mostly-wooded trail travels approximately a half-mile to the lowest pool at Fish Camp Falls. You can keep going on an unmaintained path by the creek up to the Arrowhead and Skinny Dip watering holes.
Start just south of Tenaya Lodge in Fish Camp, then turn onto Jackson Road/Big Sandy (Road 6S67). From there, drive about two miles until you reach an abandoned fruit orchard and an old driveway. Follow the driveway past the metal gate to an abandoned cabin and you are at the trailhead for Jackson Hole/Lewis Fork Ditch.
