Having walked around 70% of the lake path, and visited the steam holes to see the lunch pots, we needed a quick snack before our ill-fated trip to the Dona Beija baths nearby. Had we actually received a timely message about the water contamination on 27 July, we would have entered this park instead. While the 10 euro charge appears steep, the park appeared well laid out and worth visiting. My son actually wants to visit the nearby zip wire place too (is this the same venue or entirely separate?). Me too. In short, loved strong coffee and boiled eggs cooked underground. Both were served with a smile too. The cozido (underground stew) served to the French family looked very appetizing indeed and very good value at 25 euro. Maybe next time........

The park is lush and nicely designed. Worth the €10 per person. We just want to warn patrons of a few things. We ordered the "goat stew" at the small kitchen at the entrance, thinking we'd each get a bowl of something like soup. Instead, we each got a massive many-pound platter of boiled, plain meats and root vegetables. Really, each plate would've been plenty for three people. We worked off a little lunch by climbing the 630 stairs to see a trickle of what would've been a rushing waterfall if it hadn't been at the tail end of a hot summer. Finally, we took a quick dip in the little hot tubs back down at the bottom, mistakenly thinking they might be part of a hot springs related to the nearby fumaroles. They'e not -- and they're not even all hot. Gorgeous forest. Lessons learned.

Beautiful park with dense vegetation. Entry: 10 euros. We went there around noon, but there were so many people at Lake Furnas, we decided to come back around 4pm. It takes more than 600 steps to reach the top of the waterfall. The path is beautiful, some viewpoints beautiful, but the waterfall was disappointing because it consisted of a trickle of water without interest. We were able to swim below, where the water is cold, but refreshing. I highly recommend the ride.

Don’t be surprised, it’s €3 per person to access the car park and the fumaroles, and then you have to fight with a cash machine (€10) and an automatic gate that quickly rejected you (and no agent to help you...) to be able to access the Park proper. But once back, everything is beautiful and you just have to follow the arrow paths (don't forget to take a photo of the card before going home, it will be very useful). We did all the stations except 1 and 2. Note that it goes up and down all the time. Due to the fact that admission is charged, the Park is not overcrowded and you can enjoy nature to the fullest. Do not hesitate to go for a walk to the Casa de Grená, an enchantment.

You come by car to a parking lot that costs 3€, then just behind it are the beautiful lake and the steaming volcano places that you can visit. then a little behind you can buy a ticket in the bar to visit the waterfall 10€ p.p. It is worth seeing it goes about 5 km steeply up through the forest (partly by stairs). There are 4 levels of waterfall however the last the number 1 at the top is very nice.

Beautiful park visited in an afternoon. The park is beautiful streams, waterfalls, heated water tanks, bridges, stairs very well maintained path and I think the most beautiful natural park visited! To pay attention: Entrance fee 10 € per person, there is no ticket office but only an automatic teller machine in my case did not work the POS system and fortunately I had cash notes to enter. Others for this problem failed to enter. The ticket must also be kept to go out otherwise you will remain locked in the park! Good thing I kept the tickets. Unfortunately we did not find staff to turn to in case of need or phone numbers this could become a problem.

At first, we were a bit surprised. On a (probably outdated) wooden sign an entrance fee of 3€ was charged, but in fact it was 10€. however, this park is worth every cent. The park actually consists of a gorge that you go up. There are many branches, otherwise it is already a few steps up. You walk through a veritable jungle from one great waterfall to another. In some cases you can also swim in the pools. Near the exit, bathers with warm thermal water are waiting for you. A great experience.

Grená Park as the first activity in our stay on Sao Miguel, turns out to be one of the highlights. The amazing nature marvels from the first minutes and gets better as the visit progresses. We did the climb to the waterfall, at the top of the park. Despite the fact that the waterfall was barely present due to little rainfall, in early September, we found the walk to it beautiful enough in itself. The route is clearly marked and the roads are well laid out. Definitely recommended for anyone who loves beautiful nature.

A beautiful, well maintained private park. It is open from 9:30am to 6pm (doors close at 5pm). You pay at the gate. I was there early and first checked out the volcanoes and walked around the lake. I was glad to be there by 9:30 as no one else showed up until around 11, so I got the park to myself. The hot tub, heated by a wooden stove was my favorite part.

We loved the visit, from the hot baths of the entrance and the pools of the river, to the climb to the viewpoint. It is a very manicured park with diversity of places to see and trails to discover. The price of 10€ is reasonable. The only thing that disappointed us was the visit to the main waterfall, which involved considerable effort, and was dry. Obviously it's not the park's fault but nature's fault, but maybe they should warn you first...
