One of the biggest perks (and surprise to us) in staying at Hotel Endsleigh was that all of the above was our private backyard for the weekend. The hotel's land covers over 100 acres and between an expansive lawn, a curious grotto, a river bank, and wild trees and plants galore - it's seriously a nature-lover's paradise. It was mostly grey when we walked about but when the sun did peak through the clouds, it was magical. I'm talking about a Walt Disney, sparkly, harps playing type of magical, too. Also incredible and worth noting were: leaves bigger than the entire radius of my body, fuzzy moss so green that it had to be touched to be believed, and a collection of shells and stones in the grotto that could occupy curious eyes for hours.
I saw signs for public entrance to the gardens so even if you don't stay at hotel you can swing by and enjoy the grounds. Definitely a worthwhile detour if you're ever in the Devon/Tavistock area.
