Heavily Trafficked but a fun hike. Very few bugs

Nice to get here early as there’s limited parking at the foot of the trail. Because it is during COVID time they’re only allowing you to access trail in a clockwise manner. Outhouses are closed still. You can purchase your day pass at entry but easier to do it online. Great hiking trail that takes you up and down the rocky terrain. It was more of an easy trail which was great for our leisurely hike. Beautiful view at the lookout point. Definitely recommend bug spray.

Good spot to hike. Kid and dog friendly but still gets your heart rate up. There’s unfortunately a $10 entry fee now. Best time to go is in the fall Instagram: cb_kirkby

I know the website says ten dollars for a day pass but if you go to the Eventbrite page - a day pass was only five dollars when I looked. I ordered online the day before, printed, and showed the lady manning the ticket booth. We got there around noon, there was a sign saying parking lot full so we parked on side of highway. But we walked to the parking lot and it was only half full so the sign isn’t always accurate. I thought it was a great trail - good for all ages. There are ups and downs but nothing too difficult. Everything was well marked. The view at the top was incredible and so worth the hike and the fee. Surprisingly, not a lot of people and not a lot of bugs at all! The way down is a bit rocky so watch your ankles. Reminder that because of COVID that you can only do the summit loop clockwise, so turn left at the yellow sign. Also good to note that the outhouse/bathroom is closed so good to go beforehand. Overall, my watch recorded 5km and about 2 hours total including stop time at the summit to take photos.

Very well marked trail, fairly busy. Found it to be a casual hike for the majority, with a few sections that required more moderate effort. Lots of great photo opportunities If that’s your thing and the view from the top is beautiful - also lots of room to sit and enjoy the view before heading back down.

Very busy trail. Excellent level of difficulty for beginner hikers- moderate but a little challenging in some sections. Great views and lots of space to relax at the summit.

This was amazing! Lately we’ve been sticking to 10km+ moderate hikes but with my mom with us we did this shorter one. What a treat! The view was spectacular and we went on a day with very very few bugs. Great trail!

This is pretty great for mine and my daughters first real hiking challenge. She’s four and we’ve stuck to pretty flat terrain and I figured we’d give this a shot. A few spots she struggled a bit and it was 5K so by the end there was a little struggle to persevere, but we did it! And that view. She could’ve sat there all day watching the boats and birds.

It an awesome place to go for a hike with the family. There is a small $10 fee per vehicle but it worth it. Also the cliff is the best part of the trip, perfect view of the lake and the nature that surrounds it. 9/10

We showed up expecting the trail to be open following the dates (may 15th opening and it is May 17th), and the trail was closed, with a blockade and a car with a sign saying "yes we are really closed, visit rockdunder.org". So we tried the website, and it was also down. No way of knowing the trail was closed until you arrive.

Bring exact change if you would like to pay for the day pass upon arrival. A very busy spot, but the trail is beautiful! We went the "hard" way and there were lots of areas where I needed to use my hands to help me climb up the rocky paths. The cabins along the way make great scenery.

Beautiful lookout point that my crazy girlfriend went right to the edge of...I wasn't quite as brave. There's multiple spots where the trail overlooks the river, and there's some interesting old cabins to check out as well. Would recommend doing it in the fall as the leaves are beautiful. Only downside is it was very busy and parking was scarce.
