Took the local bus at 9.15am from Alajuela station to Poas Volcano for $2.50 each - arrived at 10.30.
There are toilets there - very clean and some on main trail to crater.
There is a small shop selling snacks - expensive as you would expect - we took a picnic.
3 walks - one 15 mins to crater - another 30 mins there to lake and 30 mins back - a last 15 mins to car park.
All very easy.
Lake beautiful and crater too
But I understand what people stay - low cloud and a waste of time.
The local bus leaves at 2.30pm to return at same cost - slightly too long and we waited 1 1/2 hours in the in playing cards.
If I did it again I would go on local bus a splurge on a taxi back at about 12.30 - two girls we meet had paid $30 to get back ( between 4 is not too bad)
