"Genuinely the best guiding experience ever. ​​
​​
​Our group spent three days on Exmoor with Trail Unknown. Their knowledge, banter, experience made all the difference and I can't recommend these guys highly enough. Book now, you won't be disappointed! - Adam W

"Truly Epic. 

​​I never write reviews or use the word epic..... but here I am.  I could probably talk about it all week and if I could give more stars I would but all I will say is, if you love mountain biking and you're looking to be guided on some unknown trails, you've come to the right place. -PJS

"Every time I end the day with the biggest smile on my face!

Trail Unknown are incredibly knowledgeable on everything bike related and the mountain bike routes are always expertly tailored to the groups. -Pierre K
