Top 5 Hardest Treetop Challenge Courses to Test Your Nerve

At Go Ape, every course delivers its own unique adventure — but some are built for those who want to push their limits. Whether it’s the height, the distance or the daring obstacles, these are the courses our instructors rate as the hardest of the hard.

These top five will test your balance, endurance and bravery to the max. Ready to find out which one you’ll conquer first?

1. Grizedale, Lake District – High, Long and Wild

Set in the breathtaking Lake District, Grizedale’s Treetop Challenge is legendary for its towering platforms and epic zip lines. The final 200-metre zip to the finish line soars across the forest canopy — pure freedom at full speed.

Insider tip: If you’ve got a head for heights and love a long ride, this one’s for you.

2. Glentress Forest, Peebles – Scotland’s Giant Adventure

With platforms as high as 40 metres, Peebles is our tallest course in the UK. It’s a true mental and physical test, with a mix of tightropes, wobbly bridges and one enormous Tarzan Swing that’ll have your heart racing before you even take the leap.

3. Aberfoyle, Stirlingshire – The Big Zip Champion

Aberfoyle doesn’t just make the list — it dominates it. This course is home to two of the longest zip lines in the country, totalling over 750 metres. You’ll fly over a waterfall and deep into the valley — and that’s before you even start the high ropes. If you want jaw-dropping scenery with your fear factor, this is your match.

4. Cannock Chase, Staffordshire – Big Heights, Big Drops

Cannock Chase is one of the toughest Treetop Challenge courses in the Midlands and an all-round endurance test. Expect huge Tarzan Swings, tricky crossings and long zip lines that race through the treetops. It’s a real leg-burner — perfect for adventure-hungry teens and adults looking for a forest challenge that doesn’t hold back.

5. Alexandra Palace, London – The High Flyer

Just minutes from central London, Alexandra Palace offers an adrenaline-fuelled challenge high above the city. Exposed platforms and long, sweeping zip lines test even the most confident adventurers — especially when the wind picks up! It’s one of our most thrilling urban locations, combining height, challenge, and unbeatable skyline views.
