What time of year will you be doing the hike?
All depends on how fast you can hike and how much time you want to spend up there.
It's about 6 miles up there and 1500ft of elevation rise.
So if you can make 30 minute miles going up with that sort of elv change, it would be 3 hours up and probably something less than 3 hours back down plus whatever time you spent up there....so maybe 6 hours total round trip time....depending on time you spend stopping on the way up and down taking breaks, pictures , etc.
Or a little more conservative estimate might be 45 minute miles going up for 4.5 hours going up and maybe 3 hours down plus 1/2 hour taking pictures, eating, whatever. for a total of about 8 hours....plus breaks etc.
If you're hiking from mid July to mid August, you
should have enough daylight to get it done before dark if starting at noon.
That said, many people don't recommend hiking around that last hour of daylight since it's a time period when many animals tend to move around.
And you really don't want to be hiking after sunset anywhere in the park.....sooooooo
Personally, I would recommend you start earlier to give yourself a cushion in case "stuff happens"...like a thunderstorm.
