Eagle Creek Trail to Punchbowl Falls is anywhere between 5 1/2 to 7 miles, depending how close you stay on the trail and if you travel to the top of the falls, which I highly recommend! It's a gorgeous hike the whole way up, with a steady incline for the first 2 miles or so.
Before reaching the lower bowl, you'll pass by an even bigger waterfall on your right, which unfortunately you can't get to. The hike is rated as family friendly on most sites but with cliffs like these dropping off directly into the canyon, I wouldn't suggest small children! Once you get to the Lower Punchbowl trailhead you take an immediate left where there looks to be a great place for an overnight camping trip!
This is the first drop off you'll see to your right when you first make it into Punchbowl. With the large tree fallen across it, it makes for the perfect jump point with deep and freezing water!!
Walk past the first drop off and you'll almost immediately hit the water of the bowl. Around 65 degrees, it's the perfect cool off after the intense uphill hike! If you're crazy like me, you can walk with you backpack above your head to the cave across the water and set up a basecamp there for lunch in between swimming to the waterfall and back.
After swimming and having a snack, you'll definitely want to hike to extra 1/2 or 3/4 miles up to the top of the falls for this view...
If you aren't able to find the trailhead at Eagle Creek or the link below doesn't work, search "Eagle Creek Fish Hatchery" and park in that parking lot. It's only a 5 minute walk from the next parking lot and usually has way more parking spaces (and bathrooms) available!
After getting back to your car I definitely recommend a restaurant called THUNDER ISLAND BREWING. Only a 10 minute drive from the trailhead deeper into the Gorge, amazing beers and a view like this- why not?!
