About the South Coast Mighty Hike
Starting in Brighton, you’ll walk through the beautiful South Downs before reaching the iconic Seven Sisters. This is a challenging route, but you’ll be rewarded with stunning coastal views before a final climb up to Beachy Head.
Hike solo and meet friends along the way or sign up with a team of friends and family for a memorable day together.
Mighty Hikes support
We have many resources to help you prepare for your hike, including how to set up your fundraising page. You can also join our Facebook group and meet the Mighty Hikers community.
