I was in Puerto Rico last week for vacation. This was actually my 3rd choice of adventure. Our first two choices didn't pan out and we decided to try this 8x8 amphibious vehicle tour. Let me say it was AWESOME! I have never laughed so much or gotten so dirty in my life. Our guide, Joel, was interesting, informative and... More

If you have traveled with teens & tweens, a frequent complaint (by the kids) is that they cannot drive. They always have to sit back and have adults drive them. The 8x8 at Frontier Adventures was a welcome change. We had four kids in our group - ages 14, 13, 12 and 11. What fun they had. Each had an... More

My boyfriend really enjoys outdoor activities so we booked this mainly for him, although it wasn't my first choice to spend an afternoon covered in mud I thoroughly enjoyed the experience. Joel (our guide) was informative and helpful. We got to drive ourselves, visit a cave and see plenty of iguanas. An exhilarating, fun activity. More

Thanks to all the good folks at Frontier Adventures. My wife and I had a great time riding and driving the Argos. Our guide, Willy, was knowledgeable, friendly, and had a great sense of humour, My only complaint was that that the tour had to end at some point. Should I make it back to San Juan, I have no...

We took the amphibious tour and our guide was Joel, who gave us a great tour of the ranch. Joel and another guide named Willie were informative and had answers to any question we asked. Joel let me drive the vehicle for over an hour -- even after I got it stuck in the middle of a massive mud pit.... More

We had Joel as our guide and he was awesome. He let my 13-year old and 8-year old drive for a long time. They loved it. The ride was a lot of fun. One of the highlights of our trip. Would highly recommend it. More

The tour was more than I expected. I didn't think I was going to have so much fun. Usually tours are boring but this one was exciting and I was anxious to see what else we would explore and the history behind of it. I never thought learning about the history of Puerto Rico would have been so much fun... More

We went to Frontier Adventures to ride the amphibious ATV with Joel, our guide. Great time - great trip. Leave early if driving yourself because our GPS had a hard time finding it, and even when you get there...you don't think you are there. Fun off roading adventure....learning about Puerto Rico's history. The caves and bats were really cool. Thankfully... More

Joel took my ten year old and me for a 2 and one half hour ride on wide track 8 wheel tank type of ATV. Because it is practically untippable, Joel supervised my 10 year old who drove it at about 15 mph for about 30 minutes. We stopped to walk to caves with ancient indian drawings. Joel explained much... More
