Weekend drive

I'm going to drive to one of the three famous water falls in Japan with my family this weekend. It takes about a couple of hours.* 
Usually my husband drives but I drive at least once a month in order to not forget how to drive.

After watching the water falls we're going to a hot spring.
There are inside and outside hot springs which are separated by gender. Soaking in an open air bath makes me feel good.**

At some places wild monkeys are relaxing in open air hot springs and we enjoy watching them but at some other places monkeys enjoy watching people who are in the hot springs.***

* "It takes about a couple of hours" In this sense I usually use "about" when I'm giving number ("It takes about two hours.") so since you don't give a number the "about" sounds unnecessary. It sounds better to me as "It takes a couple of hours." or "I takes about two hours."

** I would "Soaking in an open air bath feels good to me." Although it's grammitically correct it's already assumed you're talking about yourself so you could just say "Soaking in an open air bath feels great!"

*** There are a lot of repeated words in this sentece. Try to use some pronouns to make it less "word-y." "At some places you can enjoy watching wild monkeys relaxing in open air hot springs, and sometimes they enjoy watching you back!"
