I think we laughed the whole time from when we descended into the warm mud "volcano", got manhandled/massaged, bobbed around in the mud, slithered out, and flopped down to the lake where ladies wash you off (take off your suit and everything - don't worry the water is murky enough for modesty - and bath you like a baby including cleaning out your ears, hilarious!). Trust me, you want these ladies washing out your suit after it's been soaked in mud! This is a seriously fun thing to do and the mud is a crazy feeling ... warm, mineral, unsinkable. You leave feeling very invigorated! Getting all the little extras like the massage, wash-off and photos (guy will take photos for you with your camera if you bring it to the top with you ... he's juggling about a dozen cameras at any given time and takes great photos) is totally worth it. The fee is about $1.50 per service, so for two people it was $7.50 total: seriously, why are people complaining about this? These are locals doing the work they can to earn a living.
Yes, the stairs are a bit rickety but nothing dangerous. Just be careful.
There is a little cantina where you can get beer and other refreshments afterwards. Bathrooms are *basic* with no TP ... but you knew that, travelling in Colombia ;)
We went with a tour bus of about 20 people and had lunch included at a local beach cafe on the way back to Cartagena with a few hours to relax on the beach. All in all, it was a very nice way to spend the day for 40,000 pp.
Couple of tips: Wear and old bathing suit and wear it under your clothes there (change rooms are not great) ... I think I washed mine about 15 times when I got home to get the last of the mud out of the lining. We were able to leave our bags on our tour bus which was great. Bring a towel. Take your camera to the top and the guy will take photos for you.
