It is worth going, uber is $35 from CNN here, and there is no ticket for the national park. But there are elderly and children who suggest choosing the cable car to go down, which is more worry-free. If you are still a bit tired to climb by yourself, go up the mountain for an hour. We choose the cable car up the mountain and walk down the mountain. (The cable car is round trip, did not sit down, about $15 a person, friends bought tickets did not remember)
