Solo traveler - guided day trips possible?
I'm an experienced solo traveler planning a 5-day trip to Bhutan in November. Doing my research, I see that outside of Paro and Thimphu, a guide will be necessary for most destinations. I'd prefer not to buy a packaged tour, but instead do day trips, for example Paro-Tiger's Nest-Paro or Thimphu-Punakha-Thimphu. The reason I'd prefer not to buy a 4-5 day package tour is price (obvs), and I'd also prefer to choose my own accommodation and pace (just chill for a day if I want, etc).
Would it be easy (or even possible) to arrange such trips/guides once I'm in the country? Or would it be better to have it all set up before arriving? Thanks for any advice.
