In Udhewadi, the village at the base camp, some villagers can make delicious home-cooked food for you - mostly egg/chicken curry or usal, dal along with bhakri and rice. You can also opt for snacking options like pohe, bhajis and maggi. Also available are refreshing drinks like kokam sharbat and neebu paani. You might be able to get misal pav and vada pav as well. The food is simple but has an extremely authentic Marathi flavour - a great pit-stop after a tiring trek.
However, for the trek, we recommend that you carry some snacks (dry fruits, apple, biscuits, etc) and plentiful of liquids and glucose because you won't be able to find any food while trekking.
