Ruby on Rails: Custom routes for search results

I am building an app for users to submit "adventures" and I would like to have individual pages set up to display adventures by city. I followed this advice (Ruby on Rails 4: Display Search Results on Search Results Page) to have search results display on a separate page and that works very well, but I would like to take it further and have pre-set links to route users to city-specific adventures. I'm not sure how to get the results from http://localhost:3000/adventures/search?utf8=%E2%9C%93&search=Tokyo to display on http://localhost:3000/pages/tokyo. Also, I am very new to Rails; this is my first project.

routes.rb

  root 'adventures#index'
  resources :adventures do
    collection do
      get :search
    end
  end

adventures_controller

  def search
    if params[:search]
      @adventures = Adventure.search(params[:search]).order("created_at DESC")
    else
      @adventures = Adventure.all.order("created_at DESC")
    end
  end
