Mid-February Itinerary recommendations

Hi all, I am new to national parks and planning trips. I am looking to travel to ONP around mid-february and looking for experienced travelers to recommend what I can do weather wise in the park. Me and my partner work hectic jobs and are looking to get away for a weekend, from my understanding its going to be cold. We are looking for a mix of good short hikes to beautiful areas and spending time in nature. I would love for recommendations of where we can start and cover major attractions in the park for 3 days. Thanks in advance!
