When I was younger we ran out of water on this trail... now having a filter I made sure EVERYONE had water. It's a deceiving hike, I probably filled 10-12 people by filling my bottle and squeezing it into theirs. It added almost an hour to my hike but totally worth it! Dehydration gets ya quick. #sawyerfilter #helpothers #upperfallstrail #theresseriouslynopottablewater #stockupforthistrail #ifyouthinkyouhaveenough #youdont (at Yosemite Falls)
