Hola Phil S,
Thank you for contacting us ... your question is a very valid one, however, the only answer I could think of is that since Puerto Vallarta has become a top destination in Mexico, this has made prices go up on everything not only tours. Luckily we are very happy to be able to provide some of the most competitive prices in Puerto Vallarta, as an example, you can book an ATV tour for 2 guests for only $136.00 USD much less than $100.00USD per person, the tours we offer are small groups. As of today (Dec 2019), We also offer many other affordable activities. We have zip line excursions that run between $40-$50 USD per person, horseback riding for $59 per person. We have a city tour for $25 per person an excursion to Sayulita & San Pancho for $43 USD per person. You could book a 4 Hour snorkeling tour with us for 6 people which would run about $70 USD per person. We also offer a FREE walking tour 1 day a week.
Thank you again for contacting us we invite you to visit our page to see all the exciting activities we offer.
Thank you.
