As Toby Keith said, "I ain't as good as I once was" but it didn't matter. My wife and I were 67, my son and daughter -in-law late 40's. We really had a great time and were able to do every activity that was offered. We were there during the rainy season but actually had very nice weather the entire trip. AND NO BUGS!
The white water tubing was the best, wild 50 minute ride of my life. (I had been on white water rafting vacations thru the Grand Canyon and Salmon river many years ago). Any areas that could be a problem were well covered by our guides. We we well instructed and protected by helmets and life vests.
Zip line was a new experience and very safe. Halfway in between the 7 zip line runs we were offered a repelling experience down into a narrow 40ft canyon. At the bottom we did a Tarzan swing across a stream to the opposite canyon wall. Everything was easy up to this point. At the base of the wall we realized that the only way out was to rock climb the 40 ft wall. I started to climb and was pooped about half was up. My energy was renewed when I saw my non athletic wife quickly passing me by. When I finally got to the top I vowed never again. There was really no danger because we were harnessed and helmeted and always connected to safety lines the whole time. The guides easily pulled me up the wall when I got tired.
After lunch, was a new helmet, and Horseback riding. 20 horses bunched together for a 30 minute ride to a waterfall, quick plunge off the boulders, and 30 minute ride back to the ranchero was more like being part of the wild bunch. My wife was became a victim of "trail rage", getting bit in the leg twice when she refused to let an overly aggressive horse pass her. Didn't even break the skin and she still loved it. (made a great story and we did not press charges against the lady that bit her).
The next day went on nature walking tours in, thru, and above the mountain rain forest, sky bridge and tram. All very informative, (Great Guide) beautiful and scenic. Easy walk.
The next day was the river boat tour where we finally got to see some monkeys, crocodiles, iguanas, bats, and birds in their natural habitat.
The last 3 days were at the resort, where we went kayaking, snorkeling, took non included trips including 3 hour horseback ride and half day un guided motor scooter excursion along the ocean roads and up into the mountains. (you better have some motor bike experience before doing this. 2 in our tour group crashed before even leaving the resort costing $1K each for damages. Fortunately they did not get hurt). The rest of the time was spent relaxing, reading, playing water volley ball (excellent pool) The food at the resort is OK but you can order a pizza locally or get a better meal in the town of Sumara. Town is a 20 minute walk on the beach (at low tide) or a $6 cab ride.
Every hotel was unique and adequate for our needs. (We did upgrade to Ocean View at the resort) I can't rave about the accommodations (if I could the entire package would be 5 stars) but we saw other tourists from other hotels visit ours because ours was so much better.
Unlike Mexico we were able to drink the water and not be worried. I got a tetanus shot before I left. No other shots are necessary for this tour.
The tour guide (Hero ?) and his assistants worked very hard and did a great job.
We purchased this tour on Group-on and it really would have been worth the full price for all that was included. Would recommend this tour to anyone considering a great safe adventure.
