Ecotermales is a smaller operation than Tabacon and Baldi in La Fortuna. If you want the party, go to Baldi, if you want deluxe with the price to match, go to Tabacon. They are both really nice, just a bit different that Ecotermales.
Ecotermales has a max capacity, so you will never be elbowed out at the bar getting a drink, well maybe, the fresh drinks are super. I made reservations and paid on line, which was really easy. You have the option of purchasing just entry tickets or entry tickets and a meal.
You enter in, get checked in and are given a key for the lockers, a towel and directions to the lockers/shower area. Nothing special there, lockers and hot showers, but clean. I recommend you take a change of clothes and a plastic bag to put your wet clothing in when you change. Wear sandals or flip flops, you will not need any additional footwear. From there you proceed down to the pools, there are only 4 springs, a couple large ones, 1 cold one and 1 that is really hot! They are crystal clear, all done is a grey rock which also surrounds the pools. Day or night, it is beautiful and peaceful.
You can go in the morning or the evening. I have done both, the evening is nice, the lighting in the springs and surrounding grounds is beautiful. I recommend grabbing a lounge chair and staking out a space, it can be difficult to get one if it is busy. Don't take anything you can not live without to the springs, I have never had a problem, but why take a chance.
Now for the important stuff. The drinks are great!! It is a honor bar, you order, drink and then let them know when you check out how many you have had. All the drinks, both alcohol and non alcohol are made fresh with your choice of fruit. Wonderful!!
I have had both lunch and dinner there. I enjoyed both, it is served family style with rice, fresh veggies, salad, juice water or wine if you wish. You may chose either chicken or beef. I recommend the chicken, the beef was not really great. We really enjoyed eating as a family at the large table after soaking in the wonderful springs.
You can not go wrong at any of the hot springs, but Ecotermales is a excellent value, clean, family friendly and the drinks are great! Enjoy
