The full circuit walk is amazing. You'll walk between two massive rock walls and there are two lovely lookouts. The walk is rated difficult but there is only one small section that is a bit challenging just before the second lookout. Persevere as it is worth it. I'm in my 60s and did this walk fairly easily. This experience surpassed Uluru in some ways as it is so up close, dramatic and personal.

Definitely do this. My partner found it the highlight of our whole central trip. The walk itself isn’t hard. There are a few parts you get puffed. There is one rock face you need to scramble up but it’s pretty easy even for a someone with no experience. Don’t need particularly good fitness to do this walk. It’s long and there are parts that are hot and cold depending on where you’re located. The views are great. Take water and some snacks and a camera! Great way to see the Olgas.

A stunning walk through the canyon with red rock rising on all sides. Head to the second lookout and continue on down the steep steps to avoid the crowds heading back the way they came and to see the many 'heads' of Kata Tjuta before rejoining the main trail back to the first lookout. Simply the best!

this hike allows you to go up close to Kata Tjuta. i did the entire circuit in a counter clockwise manner, which is the park's recommendation if you follow the signs. the most scenic portion is between Lookout #1 (Karuu) and #2 (Karingana). after Karingana, there is a steep hill where you descend before heading back to car park on a fairly flat path. i took 2h to complete the entire circuit including photo stops. the park suggested duration is 4h which is quite generous. it is not recommended to walk the entire circuit if you start later than 11 am (more applicable for summer season imo). there are multiple water stations along the way. there is no mobile signal (Telstra) except at the trailhead near the information board.

We did the four hour trip with SEIT tours and really enjoyed it. The view from the second look out is amazing as is the composition of the conglomerate rock that the domes are made of. Our guide was very informative and allowed plenty of time to stop and take in the views. The walk is achievable for people of varying levels of fitness as long as you are prepared to take your time and take the right gear. We went well prepared with hats, sunscreen, water and food and although the weather stayed mild we are glad we went prepared. You could really get caught out on a hot day as the second half of the loop is very exposed with little shade. Oh, and one of the funny looking fly nets would be a good investment as the weather warms up. We didn't take any photos of the domes as requested by the traditional owners. There are already plenty on the Internet and none of them do justice to seeing them up close and personal.
