The lower well is open for 2026 and tested clear of bacteria and is potable water.

What is TMLOA – Thunder Mountain Land Owner Association? It is wonderful retreat nestled in the mountains above Lava Hot Springs. Membership is required. There are an estimated 319 lots. Entry, stay, and camping is restricted to association members’ sites only, and their family and friends, and sites may include tents, trailers, and cabins. Membership association dues are $175.00, per lot and for 2025, 2026, and 2027, a road assessment of $300.00, per lot.
A gate to Thunder Mountain allows association members to enter with an assigned fob, a oode entry no longer is available. The fob entry provides more security, with the added camera view at the gate entrance.
All roads are gravel with maintenance overseen in spring and summer months. Water is obtained from a well by the shed and up higher on the mountain is a spring. Water is for use by association members and is tested for bacteria and is potable water. There is a metal shed at the entry where an annual landowners meeting is held the second Saturday every June. When available, there is space inside the shed for association members to rent for recreational vehicles only, i.e. snowmobiles, ATV, or smaller side by sides that will reasonably fit.
Spring and summer has a lot of activity on the mountain. Wild animals are a common sight. Fall is gorgeous with the beautiful colors of autumn leaves. On a crisp winter day a land owner could view the wonder of nature while covered with snow.
Lava Hot Springs is a quaint little town in southeast Idaho, north of TMLOA, with a grocery store, restaurants, hardware, swimming pool, and of course what Lava is famous for, the natural hot pots.
