go on a picnic under the blossoms

[Itasan]

"People hold parties or go on a picnic under the cherry blossoms."
Is this sentence correct? I wonder if people go on a picnic
under the cherry blossoms.
How about:
1. People hold parties under the cherry blossoms or
go on a blossom-viewing picnic.
2. People hold parties under the cherry blossoms or
go on a picnic to view cherry blossoms.
Thank you.

"Go on a picnic under the cherry blossoms" is fine.
