El Yunque advice

I’d like to visit El Yunque next week, but I’m a bit concerned with how busy it seems. Would it be better to go later in the afternoon rather than right at opening to avoid crowds? Are there any nearby alternatives? Thanks in advance!

Edit to update: Thank you all for the great advice! It definitely pays to go as early as possible to avoid the chaotic corralling of children, tours taking up every inch of the sidewalk, and hungover people frowning in your photo’s of waterfalls. It was breathtaking and I’m so thankful I went!
