Yes, there are far more beautiful beaches in Costa Rica, but if you have obligations in San Jose like I did, it makes a nice trip just for a day or two as it’s only a two hour bus ride there, and less than an hour and a half return trip. I found it interesting that on almost all of my excursions outside of San Jose, the return trip was substantially shorter, mostly due to the capability of the bus and the mountainous terrain where you’re always riding on a road at an angle.
This is definitely not the most safe town surrounding a beach in Costa Rica. It’s known for its prostitution and ease of access to these women. To stay safe, I stuck to the bar connected to the hostel we were staying in. The streets aren’t well lit so if I had gone much farther, I may not have found my way back.
