YOSEMITE NATIONAL PARK (KFSN) --Right now, people from around the world are heading to the park to get a glimpse at its beautiful waterfalls and Half Dome.
Waterfalls at Yosemite National Park are flowing so strong that you might get a good mist if you stand close enough. Up high at Glacier Point, you can see their power.
"This year we've got a lot of snow in the high country-- a lot of snow melt which means those waterfalls are really full. May is certainly the peak flow time for these waterfalls," said Sabrina Diaz, Yosemite National Park ranger.
Diaz said those waterfalls, wildlife, and incredible vistas are attracting tourists.
Officials said visitation is up by about 40-percent due to the waterfalls, lower gas prices, and centennial celebration.
The Cherry family of Los Angeles came up to get a glimpse of the sunrise from 7,000 feet up at Glacier point. They said visiting Yosemite is awe inspiring.
"We come up every year. This is our fifth year in a row to hike, just ride bikes, and enjoy God's creation," said Mike Cherry.
Officials said hotels have already been full with guests and rangers are encouraging people to use alternative transportation like the YARTS bus or riding the shuttle.
They also said coming during the week can give you the freedom to enjoy the park without the crowds.
Park officials said cables will be put up at Half Dome after Memorial Day and permits are needed to climb the Granite Peak.
Also, sightseers will have a longer window to see the waterfalls, thanks to Mother Nature.
"Last year they were ending by around June, and this year we expect them to still be flowing in July and maybe even into August," said Diaz.
Rangers said the busy spring season is just a glimpse of what's ahead this summer.
About 4 million people are expected to visit the jewel of the park system this year.
