I'm a newbie in San Salvador, but have taken on the task of finding day trips out of San Salvador for a small group of 8-10 adults. A recent trip was to the Termales de Santa Teresa, with lunch nearby. I'm trying to arrange an indigo workshop and also an archaeology trip. And a zip line. Do any of you have suggestions beyond what i can find in Lonely Planet or Tripadvisor? Thanks. (I'm Robert the Tour Guide)
