The steep sand dune will be open 8 a.m. to 6 p.m. on weekdays and 8 a.m. to noon on Saturdays. The park will be off-limits to adults on Sundays.
The city has spent around $60,000 to revamp the park to prepare for the Monday reopening.
The towering sand dune is a popular workout spot, and if you want to use the steep terrain for exercise, it'll cost $1.00 for a one-hour visit.
Also, visiting the sand dunes now require reservations. Park users must go online to reserve a designated time slot to access the park.
Don Trucker has been coming to the park for more than 30 years.
"The last five or so years, it's gotten really crowded especially on weekends and summer evenings, so I think those are the times that are in most need for regulation to keep the usage down," said Trucker.
Some park users disagree with the new sand dune restrictions.
"I don't think it's fair, but we're going to do what we have to do to get back on the dune right now and hopefully, we can get the fences down and have this be an open park again," said a park user Jennifer Fraser.
"We'll see how it goes. This is just the first day, and we're not sure how it will turn out and this is certainly better than what it was before, so that is a step in the right direction," said Dr. Samir Shahin, a Manhattan Beach resident.
