This trail is closed until May 15th EVERY YEAR. Commencing in 2017, access will not be free. It will require either a "day pass" or a "season pass". A soaring lookout over the Rideau Waterway, and a local landmark for generations. Well-marked trails through mature woodlands, following shorelines and finally climbing to the rocky summit. Part of the Rideau Waterways Land Trust, trail development and maintenance by the Rideau Trail Association. This magnificent site was owned for generations by the Boy Scouts of Canada. In 2005 it was purchased by the Rideau Waterways Land Trust and is now available for hiking through their kindness.

Beautiful view from the top, but very muddy in areas and do not forget insect repellent.

My 8yr old son and I did this trail for the first time today. Great varied turf and elevation with beautiful vistas...was a bit muddy and wet coming back once down off the highland but we had fun. Bug spray is a good thing to have.

Very nice hike! I was here on May 30 and the skeeters were
super bad, I would seriously suggest lots of bug spray!

It's a wonderful hike, but I've heard that it is closed to the public. Double check before you head out.

Thank for your correction re:my review, yes we discussed with them about it; that they should not have just walked past even though others were, but they did apologize, and said it will not happen again.

As a member of the Rideau Waterway Land Trust (with the exception of last year as I did not receive a membership renewal and could not find up-to-date contact information on the website :( ) and former summer student employee, I am glad to see that the Trust is in fact still active and has begun to do something about the Dunder situation. The last time I hiked in 2015 there were several people off-trail and loose dogs running about despite signage explaining trail use protocols and that the area is an ANSI and has sensitive flora and fauna. Speaking with these people they were incredibly rude and could not be persuaded that the property is indeed private. I'm glad that trespassers are finally being dealt with and hopefully the OPP will become more involved in preventing trespassing but I also hope that this leads to more respectful use of the trails when they are open. The Land Trust does great work in preserving conservation lands along the Rideau corridor and trails such as Dunder can act as flagship properties to help generate funds towards current and future conservation and preservation efforts if people respect them. Also, I hope that those who have been unable to read a sign for the past few years finally achieve that skill. It is truly pathetic when educational institutes like Queen's and Algonquin college are advertising to their students to hike Dunder when it is clearly CLOSED. Looking forward to becoming a RWLT member again once the website is updated.
