How long should I plan to spend here?

1-2 hours

You could spend an afternoon there or just pull up to take done pictures. Choice is yours

30 minutes is good, it's a great photo but not much else

1-2 hours is good

I think almost 1 hour is enough ..

It's a smallish park but has wonderful views. It's a nice place to take a break from your other activities, during the day. 45 min if you are alone just wanting a short break but maybe up to 2 hours if you have kids or a dog, want to have a picnic or just want some extended relaxation time.

As long as you’d like, no bathrooms

1 hour or more , met other people and there din friendly park
