The most incredible hike I have have ever been on! Highly highly recommend. We used google maps to get us to the start of the trail, once we got to the gazebo the trail is very obvious from there to the top (we had to go under a barbed wire fence to find the trail at the start). At the top we had a hard time finding the trail down to the lake. Some hikers leaving the volcano pointed it out to us. It is steep, but if you’re fit it’s very worth it. We came out looking like we rolled around in mud (and at times on this trail we probably did). But one of our favorite days in CR by far. Enjoy!
