Hawaii is a dream destination for any nature lover. Being world-famous for the surf, the Hawaiian islands also have some of the most scenic hikes you could find on the planet and hiking the Ka\u2019au Crater Trail in the island of Oahu is certainly one of them!<\/p>\n I didn\u2019t even know of the existence of the Ka\u2019au Crater Trail before arriving to Oahu and talking with some friends I met one day at the beach in Honolulu they mentioned it as one of the toughest and most scenic on the island. Definitely one of the best hikes in Hawaii.

There\u2019s no sponsored content on this blog.<\/p>\n The Ka\u2019au Crater Trail is now one of my all-time favourite one-day hikes, keep reading and you will find out why!<\/p>\n Hawaii is not the most budget-friendly place to go backpacking low-cost, but luckily the island of Oahu is well linked by bus and it\u2019s not so expensive to get to the start of the Ka\u2019au crater trail (for Hawaiian standards\u2026) if like me, you\u2019re also travelling low cost, make sure to check my guide to travel in Hawaii on a budget<\/a><\/strong>.<\/p>\n If you\u2019re travelling with a few friends you could rent a cheap car and will cost pretty much the same that going by bus. I\u2019ve found in the past really cheap car rental deals on RentalCars<\/a><\/strong>. If you\u2019re 3 or more I\u2019d definitely suggest to take a look at doing so.<\/p>\n When hiking alone or as a couple, the cheapest option to go hiking to the Ka\u2019au Crater Trail is by bus. A single journey in the island of Oahu costs US $2.75, but you can get a day-pass for US $5.50<\/strong> that gives you unlimited rides so make sure to buy a day-pass when out there adventuring!<\/p>\n You can find the best bus combination on google depending on where you\u2019re staying.<\/p>\n When I was backpacking in Honolulu I stayed couchsurfing in the Ala Moana area which was beautiful and far enough of the crowded Waikiki Beach area. From Ala Moana centre it took me about an hour to get to the start of the Ka\u2019au Crater Trail.<\/p>\n Have a look at accommodation in Honolulu in case you don\u2019t find a Couchsurf host.<\/p>\n No matter where you start your journey, it\u2019s likely you will connect to the 9S bus<\/strong> which goes around the Palolo valley and will drop you at the bus stop \u201c10th Ave + App Waiomao Rd<\/strong>\u201d, once off the bus you walk slightly uphill on a residential area for about 15-20 minutes until you reach the start of the trail.<\/p>\n This was the wildest hike I did on my few days in Oahu so it\u2019s certainly not your Sunday stroll-by-the-park kind of walk. The Ka\u2019au Crater Trail is technical and even dangerous at times so make sure to bring good hiking gear!<\/p>\n For any one-day hike I do, I always carry my Salomon Daypack, Camelback Reservoir and if I know it\u2019s going to be challenging or it has been raining then I also take my Salomon Hiking Boots. Although not essential, a quick dry towel can be handy if you decide to take river swim!<\/p>\n I saw a couple of guys in sneakers. They didn\u2019t make it to the top. Perhaps you could do it, but if you have a good pair of boots then it\u2019s going to be a lot safer!<\/p>\n Plenty of water and some snacks are always a good idea when spending a few hours out on the mountains.<\/p>\n Download offline maps just in case, I always use the maps.me app and it\u2019s my preferred choice wherever I go in the world.<\/p>\n The Ka\u2019au Crater trail is not for the faint-hearted. It involves waterfall climbs, a windy and narrow volcano crater rim walk, clad-like slippery slopes, steep descents, steep ascents, mud, mud, mud, lots of stream crossings, wild narrow paths and peace, so much peace\u2026\u2026so awesome!!!!<\/p>\n At just over 7.5km and some 600m of climbing is not super long in distance but due to the difficulty of the terrain it took me a good 5 hours to complete, including marvelling a lot and some time lost cross-crountrying a bit of a dangerous cliff.<\/p>\n The very first thing you will see when arriving to the trailhead is a sign mentioning that the Ka\u2019au Crater is an unmaintained trail<\/strong> and you have to continue at your own risk. Awesome!<\/p>\n It will not take more than a few steps to discover what the sign was referring to, as the trail quickly goes downhill over muddy and slippery terrain. There are some support ropes at times though. Not dangerous at all but just a little taster of what will come later.<\/p>\n Although it\u2019s not maintained, the Ka\u2019au Trail is easy to follow and almost impossible to get lost as it\u2019s well marked with some pink laces when there\u2019s not a clearly visible path. There\u2019s only one point at a river crossing that could confuse you but there\u2019s an actual sign indicating to continue following the stream.<\/p>\n 5 or 10 minutes after you start, you will be following some old water pipes that go next to the trail, at first I was a bit disappointed to see this as it\u2019s not particularly wild and just a constant reminder of being on a civilised man-made path. But eventually you will leave the pipe behind and the adventure will continue!<\/p>\n The route to go hiking the Ka\u2019au Crater Trail is a loop that starts with a \u201csingle-lane\u201d path for the first 750 meters, this path will be the same to start and to finish the trail.<\/p>\n After a few river crossings and 750 meters from the start you will have the option to go either left or right as that\u2019s the start\/end of the loop.<\/p>\n I didn\u2019t know which direction would be better to hike the Ka\u2019au Crater<\/strong> so I studied a little bit on the limited information I could get from maps.me (I was offline) and decided to take the path on the right to go counter-clockwise<\/strong>. My logic was because there are two waterfalls on the trail and going on this direction you climb them up instead of down which I consider it safer.<\/p>\n When I finished the loop a few hours later I was glad that I took that counter-clockwise direction on the Ka\u2019au Crater Trail as I think the super slippery areas had better positioned support ropes when going on this direction.<\/p>\n Even that it may sound difficult to climb the waterfalls, if you go slowly and look at where the support ropes are located it can be done very safely.<\/p>\n One of the couples that I saw on the day told me they didn\u2019t know how to climb the second waterfall. On this one you just need to find a slightly steep trail when you\u2019re about halfway of the waterfall. I guess they were just looking for more ropes to keep climbing next to the waterfall.<\/p>\n Remember, just look around you and you will find the trail or rope as it\u2019s all easy to follow.<\/p>\n When leaving the waterfalls behind you have another intersection for the crater rim loop. I recommend to always, along the entire trail, take the right path so you keep going counter-clockwise. Only when you pass the highest section of the Ka\u2019au Crater Rim you need to take a left to stay on the rim instead of going to the nearby mountain.<\/p>\n After the second waterfall the trail is mainly flat with some slight climbing. This goes through a beautiful dense forest. Make sure to stop for a moment and listen to all the sounds of nature!<\/p>\n Once you start hiking on the crater rim you will go on a constant climb and the views will finally start to pay off!<\/p>\n This section is where you will be glad to have brought a good pair of hiking boots as it\u2019s steep, slippery and narrowly dangerous at times.<\/p>\n The clad-like terrain is really steep at times. Most of these climbs have support ropes but on a good few of them you will have to scramble. Be careful with loose rocks if you have someone hiking behind you!<\/p>\n Reaching the highest point of the Ka\u2019au Crater Trail is what makes the adventure worth it. From the main peak there\u2019s almost a 360\u00b0 view of Oahu, speechless.<\/p>\n Even that I had a cloudy day I could still see far in the distance the north shore beaches and the touristy Waikiki area across the crater.<\/p>\n The only thing that breaks the beauty is the presence of some electric towers. But hey, sometimes you cannot have everything! even more on a well developed island.<\/p>\n I spent a good time enjoying the scenery until finally deciding to move on.<\/p>\n To go down the Ka\u2019au Crater Trail is not any easier, it\u2019s in fact much harder!<\/p>\n Similar clad-like climbs that you had to go through on your way up will be waiting for you on the other half of the crater rim.<\/p>\n In many of them there were no ropes. That\u2019s one of the reasons I find the counter-clockwise hiking direction safer.<\/p>\n On the rope-less, steep and slippery descents I just had to kneel down and slide\/scramble as it was simply too difficult\/dangerous to walk.<\/p>\n In some of these descents there are some trees that are good to gain some support or to break on your sliding! So much fun!<\/p>\n There are also some really narrow sections going through overgrown vegetation so it\u2019s easy to miss your step. Be extra careful if there are strong winds!<\/p>\n Finalising the crater rim you get again another intersection which takes you to keep going on a loop of the rim (if you take the left) or just take the right and you will start hiking down the mountain. As I mentioned above, always take the right on all intersections<\/strong>! \ud83d\ude42<\/p>\n Leaving the Ka\u2019au Crater Rim behind, you will find a similar terrain to when you were coming up, except that you will not find any waterfalls and no river crossings until you finally reach the end of the loop which takes you to the 750 meters \u201cstraight line\u201d that you walked at the very beginning of the trail.<\/p>\n What a wonderful hike!<\/p>\n -You will get wet. If not by rain or by all the river crossings, you will get dirty with mud so you will eventually end up in the river washing yourself! \ud83d\ude42<\/p>\n -Plan 5-7 hours in the mountain, do not start too late as the final section will get dark soon as it goes through dense forest.<\/p>\n -Bring good hiking boots! it will help massively on the steep slippery sections.<\/p>\n -Take always the path to your right in case of intersections for a counter-clockwise hiking direction (my personal preference)<\/p>\n No. This is not a beginners hike specially if it has been raining. Right from the start of the Ka\u2019au Trail you will see a sign warning you that the trail is unmaintained and that you should only continue at your own risk.<\/p>\n That\u2019s not to say that you need to be a mountaneer, someone that it\u2019s not a confident hiker can still go with someone more experienced but if you\u2019re looking for a simple easy walk then this is defintely not for you.<\/p>\n![\"Hiking](\"https:\/\/planetofadventures.com\/wp-content\/uploads\/2019\/10\/20191001_140904-01-1024x471.png\")
