The reservation system is kind of upsetting. You only reserve online and pay there, but if you don't reserve beforehand, you have to drive really far to get reception or annoy a disgruntled lady with Wi-Fi at a campsite. She'll charge 1000 pesos. The online system often gets errors, and you have to redo the whole thing. Also required for each person to fill out separately. It's just for gathering info. We used the same system going into Torres de Paine, but there was WiFi and an attendant to help you fill it out.
The path to the highest and best view would be challenging for some but doable. A decent amount of large or muddy steps. It's a great view of a glacier, but if you've just walked on Exploradores, it's underwhelming. The glacier doesn't hang anymore, so that uniqueness isn't there.
Also, the park closes at 4:30, and they won't let you in after 2. It cost $22 USD for two people.
