Fodor's Review

Panoramas from this 760-foot extinct volcanic peak, once used as a military fortification, extend from Waikiki and Honolulu in one direction and out to Koko Head in the other, with surfers and windsurfers scattered like confetti on the cresting waves below. This 360-degree perspective is a great orientation for first-time visitors. On a clear day, look east past Koko Head to glimpse the outlines of the islands of Maui and Molokai.

To enter the park from Waikiki,

take Kalakaua Avenue east, turn left at Monsarrat Avenue, head a mile up the hill, and look for a sign on the right. Drive through the tunnel to the inside of the crater. The ¾-mile trail to the top begins at the parking lot. Be aware that the hike to the crater is an upward ascent with numerous stairs to climb; if you aren't in the habit of getting occasional exercise, this might not be for you. At the top, you'll find a somewhat awkward scramble through a tunnel and bunker out into the open air, but the view is worth it.

Take bottled water with you to stay hydrated under the tropical sun. To beat the heat and the crowds, rise early and make the hike before 8 am. As you walk, note the color of the vegetation; if the mountain is brown, Honolulu has been without significant rain for a while; but if the trees and undergrowth glow green, you'll know it's the wet season (winter) without looking at a calendar. This is when rare Hawaiian marsh plants revive on the floor of the crater. Keep an eye on your watch if you're here at day's end: the gates close promptly at 6.

Claustrophobics Beware!

I know no travel guides I've seen warn about this: but after a VERY strenuous and long stair climb and walk (we are young and not overweight and we were drenched in sweat and our knees ached like crazy)--you have to pass through two very dark and narrow tunnels. I am mildly claustrophobic and had a very hard time (at that point with all the hell I'd had to go through to get there--I was not going to have it all be for nothing). Do NOT attempt this

if you suffer from any appreciable amount of claustrophobia--you'll go through heck to get to the top and then you won't be able to see the pinnacle. I would never have attempted it had I known.
